Current as of October 30, 2026, against the Racing Industry Act 2020 (section 74AAA, in force since 28 June 2025) and TAB NZ’s published betting rules.

If you have placed a bet in New Zealand before, you have placed it with TAB NZ — either at a retail outlet, on tab.co.nz, or on the TAB app. That is the entire domestic market, by law, since 28 June 2025. Two brands cover it, TAB and Betcha, and both belong to the same operator. Everything else a New Zealand punter sees advertised — the offshore bookmakers with crypto deposits, the apps with twenty-eight odds formats, the sites pushing boosted odds and accumulators — sits outside the law that the Department of Internal Affairs enforces.

This page walks through the choices that decision opens, and the price of each one. It explains what decimal odds say, what a margin takes off the top, how a multi is built and settled, and how TAB NZ’s two brands and a shelf of unlicensed offshore bookmakers compare on the criteria that matter to a New Zealand punter. The angle throughout is choice: which path exists, what it costs, who it suits.

The statute that closes the market to one provider

New Zealand’s betting law does not regulate a market — it closes one. Section 74AAA of the Racing Industry Act 2020, inserted by the Racing Industry Amendment Act 2025 and in force since 28 June 2025, says that no person other than TAB NZ may offer racing betting, sports betting or other racing or sports betting to a person in New Zealand, regardless of where that operator is resident or incorporated. The Department of Internal Affairs told providers serving New Zealand to withdraw with immediate effect.

The change is not the kind that leaves room for licence applications: there is no licence route for another bookmaker and no register of licensed bookmakers, because there is only one lawful provider. What the law does, in plain terms, is assign liability to the offshore operator. It does not block bookmaker websites; it puts the offence on the side offering the bet.

Two things follow for a New Zealand punter. First, the lawful option is narrow and is the same operator twice: TAB and Betcha, both run by TAB NZ. The Racing Industry Act names TAB New Zealand as the holder; Entain runs the business under a 25-year partnership signed in 2023 that gives Entain a 50/50 share of gross profits, with at least $150m a year going to TAB NZ for the first five years, and a one-off $100m payment to the racing sector. Betcha is the younger of the two brands, the online sister that adds the social features TAB does not lead with. Second, an offshore bookmaker advertising to New Zealand punters is, in DIA’s reading, breaking section 74AAA. Whether a player gets prosecuted for using one is a different question — section 19(4) of the Gambling Act 2003 (inserted in 2025) says an individual cannot be convicted simply for placing a bet with an offshore operator in breach of section 74AAA — but the operator’s risk is the operator’s, and the player’s risk is the player’s.

That split matters because the rest of this page turns on it. TAB NZ and Betcha are subject to New Zealand’s harm-minimisation framework: deposit limits, time-outs, self-exclusion across both brands, a Problem Gambling Levy, an independent regulator. An offshore bookmaker is subject to its own jurisdiction. The offshore sites this page reviews have Curaçao, Anjouan, Tobique or Comoros licensing — those licences do not reach into New Zealand and give no New Zealand complaints route.

What a New Zealand punter can legally bet on

TAB NZ offers racing and sports betting, fixed-odds and pool (tote). Its published betting rules define the bet types a New Zealand punter has used for years: Win, Place, Each Way, Quinella, Exacta, Trifecta, First Four, Double, Treble, Daily Double, Running Double, Quaddie and Big6 on the racing side; Multis, Same Game Multis and head-to-head lines on the sports side. Live betting appears in the TAB NZ apps; whether the law restricts in-play markets the way some other countries do is not settled, so live betting is on the menu without a clear statutory ceiling.

What is not available from a lawful New Zealand source: a betting exchange, spread betting, politics markets, novelty markets. The racing codes TAB takes bets on are thoroughbred, harness and, until greyhound racing closes in stages from 1 August 2026, greyhounds. From 1 August 2026 offshore operators may not take bets on greyhound races either.

The operator, the regulator and the levy

The Department of Internal Affairs monitors compliance with the betting prohibition under section 92A of the Racing Industry Act 2020. The Racing Integrity Board runs the racing side — whip use, swabbing, race-day integrity. Inland Revenue handles tax: recreational gambling winnings are generally not taxable for a New Zealand player, prize money from TAB horse, dog and trotting races is not taxable, and a punter whose betting counts as a business is in different territory altogether.

TAB NZ pays the Problem Gambling Levy, set at 0.74% and in force from 1 July 2025 to 30 June 2028. Offshore operators supplying New Zealand residents pay an online gambling duty (12% of profits since 1 July 2024, rising to 16% from 1 January 2027), but the duty being payable does not make the offer lawful — paying tax is not the test that section 74AAA sets. The point-of-consumption charge on offshore racing and sports bets ceased on 30 June 2026.

The Advertising Standards Authority’s Gambling Advertising Code applies to the ads a New Zealand punter sees from the lawful market: no targeting of children (under 14) or young people (14 to under 18), judged by context, appeal and expected audience (25% or more of the audience counts as significant where accurate data exists); no encouragement of harm; truthfulness with terms available. There is no New Zealand equivalent of a “whistle-to-whistle” broadcast ban.

What a decimal odds figure actually says

A decimal odds figure is the multiple of the stake that comes back if the bet wins. Read at face value, $2.10 means a $10 stake returns $21, of which $11 is net profit; $1.50 means a $10 stake returns $15 with $5 of net profit. The stake is always returned on top of the net profit, which is the difference between decimal odds and the fractional odds written on British slips.

New Zealand bookmakers write odds in decimal form by convention, and TAB NZ does the same — the slip says $2.10, not 11/10. The same stake on a $10.00 line returns ten times the stake because the probability the operator has priced in is small, and a $1.02 line returns the stake and almost nothing else, because the outcome is treated as near-certain. The lower the odds, the more the bookmaker thinks it knows.

What a decimal odds figure does not say is how much of the stake the bookmaker keeps on average. That is the margin, and the odds are quoted before it is taken out. A two-way market at $1.90 on each side pays back $0.95 for every $1 bet across the two outcomes combined — a 5% margin. The maths is straightforward: the implied probabilities of $1.90 are 1/1.90 + 1/1.90, or 52.63% + 52.63%, which is 105.26%, and the gap between that 105.26% and the 100% of a “fair” book is the margin. The bettor loses 5¢ on every dollar over many bets, before any individual bet is settled. Worked at the level of a single illustrative example, the band on a two-way market is what the page uses as a reference, not a quoted price: a market at $1.90 / $1.90 keeps 5% on average, a market at $1.85 / $1.85 keeps around 8%, a market at $1.95 / $1.95 keeps roughly 2.5%. The narrower the spread on the two prices, the smaller the margin and the closer the bookmaker is paying out close to a “fair” 100%.

What a margin costs in dollar terms

A 5% margin is small by the standards of betting markets, but it compounds. A punter betting $50 a week at an average 5% margin loses about $130 over a year before the bets are settled — and that is before a losing streak is even started on. A 2.5% margin halves that figure, an 8% margin nearly doubles it. The market a punter picks matters less than the margin a bookmaker charges on it; a 1X2 market at 5% costs less than a same-game multi at 8% even though both markets look like “the same bet” to a casual reader.

How odds and probability connect

The implied probability of a decimal price is the reciprocal: 1 divided by the odds. $2.00 implies 50%, $3.00 implies 33.3%, $10.00 implies 10%. Adding the implied probabilities of every outcome in a market is how the margin is read: a sum over 100% means a “fair” book with no margin; a sum over 100% means the bookmaker’s edge. The market a punter chooses is partly a choice of which margin they will pay.

The bet types TAB NZ’s rules cover, and how each is settled

TAB NZ’s betting rules cover the racing bet types a New Zealand punter has used for decades and the sports bet types the apps now lead with. The shapes differ — racing pays on finishing order, sports pays on a single outcome — and the bet construction that sits behind each one is the same.

Win, place and each way

A Win bet pays if the selection finishes first. A Place bet pays if the selection finishes in the place positions the race declares — typically first, second and third in field sizes of eight or more, fewer places in smaller fields. An Each Way bet is two bets of equal stake: one Win and one Place. The stake on an Each Way bet is doubled for the purposes of the payout, because the punter is placing two bets through one transaction.

Quinella, Trifecta, First Four

These are exotic bets. A Quinella pays if the punter picks the first two finishers in either order. A Trifecta pays if the punter picks the first three in order. A First Four pays if the punter picks the first four in order. The odds on these markets are not a simple multiple — TAB NZ runs pool betting on the more popular exotics, with the dividend declared after the race settles, and the payout to a winning unit depends on the pool size and the number of winning units.

Doubles, Trebles, Quaddies and Big6

A Double pays if two named races are picked correctly; a Treble adds a third. A Quaddie is a TAB NZ staple — pick the winner of four nominated races at a meeting, usually the last four, and the dividend is paid from a pool with no fixed odds. Big6 is the same shape with six races. A Daily Double is the first and a specified later race; a Running Double is two consecutive races.

Multis, Same Game Multis and Popular Multis

A Multi is several selections combined into one bet — the prices multiply, the stake is multiplied by the combined price if every leg wins, and one losing leg voids the whole bet. A Same Game Multi (SGM) is the same construction with the legs all drawn from one event: a rugby match with head-to-head, total points and first try-scorer combined into one slip. The TAB NZ app lists one-tap Popular Multis — pre-built combinations the app surfaces — and the operator’s own data shows the bonus attached to a multi that falls short by a set number of legs can return some bonus cash (terms and conditions apply on the specific offer, not the multi itself).

Place Extra

Place Extra lets a punter back a runner to finish up to 10th in selected races. It is the longer-tail version of a Place bet — the same bet type, a wider place range, a smaller price per unit.

Cash out before settlement

Cash out lets the punter lock in a win or a loss before the bet is settled, at a price the bookmaker offers at the moment of the cash out. TAB NZ’s apps support it; offshore brands’ terms say it is “not guaranteed to be available” and exclude free bets and risk-free bets. The price the bookmaker offers at the moment of cash out is its own price, not the original odds, and the punter is accepting whatever the live market shows.

TAB and Betcha: the same operator, two brands

TAB and Betcha are not rival bookmakers. They are the two online brands of TAB NZ. A punter who opens a TAB account and a punter who opens a Betcha account are customers of the same operator, with the same harm-minimisation tools reaching both accounts (self-exclusion applies across both brands), the same betting rules underneath, and the same New Zealand regulator and complaints framework above. Treating them as rivals is a marketing line, not a feature difference.

What differs is the framing. TAB is the established brand — the retail outlets, the racing heritage, the app a New Zealand punter opens first. Betcha is the social, sports-led brand: a daily Toolbox with odds boosts and insurance tools, a Bet Social section where punters chat and follow tipsters, a Playbook with match analysis. The same operator group, two surfaces, the same legal and harm-minimisation envelope around both.

TAB (tab.co.nz)

TAB is the senior brand and the one a New Zealand punter reaches first. The app — TAB – Racing & Sports Betting, listed on the New Zealand App Store under the seller name New Zealand Racing Board and first released on 8 September 2014 — covers horse and harness racing, rugby union and rugby league, and other sports pre-match and live. New customers can receive Bonus Cash that can be split across multiple bets. The app carries a 17+ App Store age rating while stating that customers must be 18 or over to bet, which is the legal threshold under section 89 of the Racing Industry Act 2020.

Trackside live race streaming runs in the app with in-app betting alongside it. Racing form, Blackbook and Jockey Challenge are the racing-only tools. The app’s same-race multis, same-game multis, one-tap Popular Multis and Place Extra options are the sports and racing bet constructors that make the difference between a casual slip and a structured multi. Deposits and withdrawals flow through a simplified wallet inside the app.

What a punter needs to know before they open an account: TAB NZ accounts need a verified New Zealand address and ID; deposit limits, time-outs and self-exclusion are in the app; the free Gambling Helpline (0800 654 655, text 8006) and Safer Gambling Aotearoa sit alongside the app as the help routes. The terms of any bonus offer are TAB NZ’s own — no New Zealand rule caps a bonus size or a wagering multiple, so what the app’s offer page says is the offer’s shape.

The verdict: TAB is the only choice in the New Zealand market for a punter who wants the lawful option, the New Zealand regulator’s protection and the New Zealand harm-minimisation framework behind the same account. The brand is the senior surface; the betting catalogue is the one the Racing Industry Act authorises. For a punter who wants the racing heritage and the retail-outlet integration that comes with it, TAB is the only address.

Betcha (betcha.co.nz)

Betcha is the second brand of the same operator group, the younger one, and the one a sports-led punter opens first. The app — listed on the New Zealand App Store under the name betcha | Sports Betting — layers the same TAB NZ betting rules with a social surface and a daily Toolbox that bundles odds boosts with insurance tools for bets that do not land. The Bet Social section is where punters chat, follow tipsters and share bets or pools; the Playbook carries tips and previews that point at specific events.

The legal position is identical to TAB: a brand of TAB NZ, the only provider lawfully offering racing and sports betting to people in New Zealand since 28 June 2025. The harm-minimisation framework is identical, the New Zealand complaints route is identical, the self-exclusion that applies across the operator group covers a Betcha account in the same way it covers a TAB account.

The verdict: Betcha is the same operator as TAB with a different surface — sports-led, social, with the daily Toolbox the senior brand does not lead with. For a punter who wants the lawful New Zealand option and prefers the social framing and the boosted-odds rhythm of the Toolbox, Betcha is the relevant brand of the same operator group. For a punter who wants the racing heritage and the retail-outlet integration, TAB is the relevant brand of the same operator group. The choice between them is a choice of surface, not a choice of operator.

The offshore shelf: ten brands, none of them licensed in New Zealand

Everything that follows the first two brands is an offshore bookmaker. None of them holds a licence that reaches into New Zealand — section 74AAA of the Racing Industry Act 2020 forbids it, and the Department of Internal Affairs told providers serving New Zealand to withdraw with immediate effect. The licences these brands do hold (Curaçao, Anjouan, Tobique, Comoros) authorise them in their own jurisdictions; they do not give them a New Zealand complaints route, a New Zealand harm-minimisation framework, or a regulator who answers to Inland Revenue. The point is not that they are scams; the point is that the law treats the offer as unlawful from the operator side, and the player side has no New Zealand backstop.

This page reviews them on the same criteria as TAB and Betcha: licence, bet types, live betting, cash-out terms, the odds formats the site offers, and what the operator’s own terms say. None of these criteria make an offshore brand lawful in New Zealand. The rating is descriptive, and the reader is the one choosing whether the offshore shelf fits their situation at all.

The table below sets the landscape. The columns are: the brand, whether it is licensed in New Zealand, and what the operator’s own terms say on the key features the rest of this section covers. The rows are the ten brands research routes onto the page; the operator’s own terms are the source for every cell that is not the New Zealand status.

The pattern underneath the table: TAB and Betcha are the only entries on the shelf that are not offshore. Of the remaining eight, two name Curaçao or Tobique licences, one names Anjouan, one names the Union of the Comoros, and four name no licence that applies in New Zealand. The bet catalogue on the offshore shelf tends to be wider than what TAB NZ covers — multiple odds formats, accumulators and bet builders, interval markets, esports, virtual sports — but the wider catalogue sits on top of a narrower legal envelope.

Thunderpick

Thunderpick is owned and operated by Paloma Media B.V., a Curaçao company (company number 146988), licensed by the Curaçao Gaming Authority under licence OGL/2024/677/0722. The brand positions around crypto esports betting, which sits across the line TAB NZ’s catalogue draws — esports is not settled as “sports betting” under the Racing Industry Act, so a New Zealand punter reaching for Thunderpick is reaching outside the law the Department of Internal Affairs enforces. This licence is valid in Curaçao; the brand has no New Zealand complaints route.

The verdict: Thunderpick suits punters seeking esports and crypto betting. It operates outside the New Zealand framework, relying on a Curaçao licence that holds no local weight.

Rooster.bet

Rooster.bet is operated by Novatrix SRL, a Costa Rica company (registration number 3-102-893958), under an e-gaming licence (No. 0000002) issued by the Tobique Gaming Commission. The sportsbook carries Live, Sports Promotions, Results, Schedule, E-sports and Predictions sections, and the site shows odds in six formats. This licence is valid in Tobique; the brand has no New Zealand complaints route.

The verdict: Rooster.bet provides a broader menu of sports sections (Live, Promotions, Results, Schedule, E-sports, Predictions) than domestic apps. It operates without a local licence, which is the primary drawback.

Winz.io

Winz.io states in its footer that it holds licences delivered by Anjouan and Tobique. This operator lacks any permit for New Zealand, and there is no local complaints route. Anjouan and Tobique licences are ineffective locally.

The verdict: Winz.io appeals to those seeking Anjouan- or Tobique-licensed services. These jurisdictions are valid where they apply, but carry no weight in New Zealand.

BetAlright

BetAlright accepts customers over 18 years of age only and runs a separate partners site. It lacks a locally recognised licence and provides no New Zealand complaints route.

The verdict: BetAlright is an option for a smaller-scale offshore experience. While it enforces an 18+ age gate, it lacks a New Zealand-recognised licence.

Sportaza

Sportaza offers cash out before an event or market is finalised, Bet Builder (one void leg voids the whole slip), multiples, Asian lines, and interval markets in 1, 5, 10 or 15 minute ranges. The brand names an Anjouan licence (ALSI-202606064-FI2), which is valid in its jurisdiction; there is no New Zealand complaints route.

The verdict: Sportaza targets punters interested in Asian lines and short-interval markets. It provides a deeper catalogue than local options but functions outside the domestic regulatory environment.

FunBet

FunBet’s sportsbook offers odds on football, ice hockey, American football, basketball, volleyball, tennis, rugby and baseball, with live betting and an open-24/7 framing. It lacks a locally recognised licence and provides no New Zealand complaints route. The brand offers accumulators and bet builders.

The verdict: FunBet provides an eight-sport catalogue featuring live betting and bet builders. Its operations are offshore and do not align with local licensing.

BillyBets

BillyBets offers three odds formats (Decimal, American, Fractional), cashback and reload bonuses on sports, a coin shop where coins collected by depositing, betting, tournaments and challenges can be exchanged for free bets and free spins, and a five-level VIP programme. It lacks a locally recognised licence and provides no New Zealand complaints route.

The verdict: BillyBets draws punters with its multi-format odds, coin-shop rewards and VIP structure. These features exist entirely offshore, outside New Zealand oversight.

BetNinja

BetNinja states it is licensed to conduct online gaming operations by the Union of the Comoros. This licence is valid in Comoros; there is no New Zealand complaints route.

The verdict: BetNinja holds a Comoros licence. This is valid in the Comoros but provides no legal standing for serving customers in New Zealand.

How the operator-level choices stack up

A New Zealand punter comparing the shelf above is not comparing ten equivalent options — the comparison is between two lawful New Zealand brands and eight offshore brands, with a hard legal line between the two groups. The line is the New Zealand regulator and the New Zealand harm-minimisation framework. TAB NZ and Betcha are subject to both; the offshore shelf is subject to its own jurisdiction and the warnings the Department of Internal Affairs publishes about overseas operators.

The features that travel across the shelf

Cash out is on TAB NZ’s apps and on several offshore brands. Sportaza’s terms describe cash out as fixed at the moment it is accepted and not guaranteed to be available; Alawin’s terms note cash out excludes free bets and risk-free bets. Across the offshore shelf, the cash-out price is the bookmaker’s live price, not the original odds.

Bet builders are on Sportaza and FunBet. Sportaza’s terms are explicit that one void leg voids the whole slip. Bet builders multiply the leg prices into one combined price; the margin on a multi is the compounded margin of each leg.

Live betting is in the TAB NZ apps, on FunBet, on 22Bet’s real-time odds and score updates, on Rooster.bet’s Live section, and on the other offshore sportsbooks that list Live Betting as a top-level menu item. The TAB NZ framing lists live betting without a clear statutory ceiling on in-play markets.

Odds formats are decimal on TAB NZ and on the New Zealand-facing side of the offshore shelf. Rooster.bet shows six formats. RoyalistPlay shows European, British, Hong Kong, American, Indonesian and Malaysian, and has an English – NZ version of the site. BillyBets offers Decimal, American and Fractional. The format a punter sees is the format the operator chooses to surface; the underlying number is the same.

The features that sit on the offshore shelf only

Coin-shop mechanics, VIP tier structures, accumulator insurance, bet builders, Asian lines, short-interval markets and six-format odds displays tend to live on the offshore shelf. The wider catalogue is the upside an offshore brand offers for the narrower framework it sits in. A New Zealand punter comparing one feature at a time ends up with a wide catalogue and a narrow envelope; the catalogue and the envelope are not separable.

What a New Zealand punter needs to know about the offshore shelf

DIA warns that overseas operators may be in jurisdictions with minimal consumer safeguards, may not return unspent credits and may not pay out large wins. None of that is certain for any one operator on the shelf; all of it is what DIA publishes about the offshore shelf as a category. A punter who has decided to bet offshore is the one paying the costs DIA describes, and TAB NZ and Betcha remain the alternative they chose not to take.

How the lawful and the offshore paths suit different readers

A punter who wants the New Zealand regulator and the New Zealand harm-minimisation framework behind their bets is on the TAB NZ path — TAB or Betcha, by surface preference. The catalogue is narrower than the offshore shelf; the framework is wider.

A punter who wants the wider catalogue — Asian lines, short-interval markets, six odds formats, bet builders across multiple sports, esports, coin-shop mechanics, VIP tiers — is on the offshore shelf. The law reads the offer as unlawful from the operator side; the player is not prosecuted for placing a single bet, but the New Zealand backstop is absent.

The grey area is the punter who wants one feature on the offshore shelf without losing the New Zealand framework. Same Game Multis are on TAB NZ and Betcha. Live betting is on TAB NZ’s apps. Cash out is on TAB NZ’s apps. The features a New Zealand punter most often reaches offshore for — bet builders across multiple sports, Asian lines, six-format odds, esports, the coin-shop mechanic — are features TAB NZ does not lead with, and the gap is the reason an offshore brand reaches a New Zealand punter in the first place.

How a multi is built, and what it costs

A multi is several selections combined into one bet. The prices multiply into one combined price; the stake is multiplied by that combined price if every leg wins; one losing leg voids the whole bet. The maths is straightforward: a three-leg multi at $1.50, $1.80 and $2.00 has a combined price of $1.50 × $1.80 × $2.00 = $5.40; a $10 stake returns $54 with $44 of net profit if all three legs win. The same $10 stake returns nothing if any one leg loses.

The cost of a multi is the compounded margin of each leg. A three-leg multi at $1.50, $1.80 and $2.00 has leg margins of 11.11%, 5.56% and 0% — the $2.00 line is a “true” 50/50 — and the compounded margin on the multi is the gap between the combined implied probability and 100%. The implied probabilities are 1/1.50 + 1/1.80 + 1/2.00 = 66.67% + 55.56% + 50.00% = 172.22%, and the gap from 100% is the compounded edge. The same three legs in a single-bet accumulator cost more than three singles on the same events because the margin compounds. A punter who wins a multi wins more per dollar staked than three singles; a punter who loses pays more per dollar staked than three singles.

A Same Game Multi takes all its legs from one event — a rugby match with head-to-head, total points and first try-scorer combined into one slip. The construction is the same; the legs come from correlated outcomes of a single event, which is why SGMs are bookmaker-built categories and why bookmakers price them the way they do.

The numbers behind an odds display

The marginal value of a price improvement depends on the price itself. A move from $2.00 to $2.10 is worth more than a move from $1.10 to $1.20, because the higher the price, the more a one-tick move adds in dollar terms. A $10 stake at $2.00 returns $20; at $2.10, $21; the $10 stake at $1.10 returns $11; at $1.20, $12. The same absolute tick is worth more at the higher price.

For a multi, the marginal value compounds. A move from $2.00 to $2.10 on one leg of a three-leg multi is worth more than the same move on a single, because the new leg price feeds into the combined price. The compounding is the punter’s upside on a multi; the compounding is also the margin compounding, and the two move together.

The implied probability of a multi leg

The implied probability of a multi leg is the same reciprocal as a single: 1 divided by the leg’s decimal odds. The implied probability of the multi is the product of the leg probabilities, which is the same calculation as the price multiplication. A $1.50 / $1.80 / $2.00 multi has a combined implied probability of 66.67% × 55.56% × 50.00% = 18.52%; the combined price of $5.40 is the reciprocal of that 18.52%. The same numbers give the same answer both ways; the audit reads them as one calculation, not two.

Where the margin bites hardest

The margin bites hardest on markets with the most outcomes — a horse race with twelve runners has twelve implied probabilities, and the gap between the sum and 100% is the bookmaker’s edge. A multi of three legs from three different races compounds the three margins into one number, and that compounded number is the punter’s effective margin on the multi.

A punter reading odds as probabilities reads them with a haircut. A $2.00 line is not 50/50 — it is whatever the bookmaker’s pricing model says, minus the margin. A punter who knows the margin has a sharper read than a punter who reads the odds at face value, and the margin is the line between the two reads.

What a New Zealand punter can do before they bet

A punter on TAB NZ or Betcha has the New Zealand harm-minimisation framework behind them: deposit limits, time-outs and self-exclusion in the apps, with self-exclusion applying across both brands. The Gambling Helpline (0800 654 655, text 8006) and Safer Gambling Aotearoa are the help routes a punter who needs them reaches for. The Problem Gambling Levy (0.74%) is what TAB NZ pays for that framework.

A punter on the offshore shelf has the operator’s own tools — deposit limits, time-outs, self-exclusion where the operator offers them — and no New Zealand backstop. The Department of Internal Affairs’s warning about overseas operators is the published description of what an offshore shelf looks like from the regulator’s side.

The accounts a New Zealand punter can open

TAB NZ accounts need a verified New Zealand address and ID; the age gate is 18. Offshore accounts need what the operator’s own sign-up flow asks for, which may or may not include a New Zealand address. The point that does not change: TAB NZ and Betcha are the lawful options; the offshore shelf is not, and the punter’s account sits on the side they chose.

What a punter needs to read before they claim a bonus

TAB NZ’s app lists a Bonus Cash offer for new customers; the offer’s terms are the offer’s own. The Mega Multi bonus of up to $50 in Bonus Cash when a multi of four or more legs falls short by a set number of legs is the same — terms and conditions apply. No New Zealand rule caps the size of a bonus or the shape of a wagering requirement, so what the app’s offer page says is the offer’s shape. Offshore brands’ terms describe reloads, cashback, accumulator boosts and coin-shop mechanics in their own words; the punter reading the terms is the one deciding whether the offer is worth the conditions.

A punter who treats the marketing line as the offer’s price is the punter who pays for the gap between the marketing line and the offer’s terms. The arithmetic is what closes the gap: turnover, minimum price, deadline, cap on free-bet winnings. The operator’s terms carry the numbers; the punter reads them, or pays the gap.

What a punter needs to know about a same-game multi

A Same Game Multi takes its legs from one event. The combined price is the product of the leg prices; one void leg voids the whole slip. The same-game multi is bookmaker-built, with the bookmaker pricing the legs and the multi; the punter reads the combined price and the leg prices, and decides.

What a punter needs to know about cash out

Cash out locks in a win or a loss at the moment the punter accepts it, at a price the bookmaker offers at that moment. The cash-out price is not the original odds and is not guaranteed. On free bets and risk-free bets the feature is excluded. A punter who cashes out a $10 stake at $1.50 for $14 has locked in a $4 profit before the bet settles; the locked-in profit is smaller than the upside of waiting for settlement, and the punter chose certainty over the unsettled upside.

What the offshore shelf’s catalogue buys, and what it costs

A punter on the offshore shelf buys a wider catalogue than TAB NZ’s apps lead with. The catalogue is real: Asian lines, six odds formats, bet builders across multiple sports, short-interval markets, esports, virtual sports, coin-shop mechanics, VIP tier structures, accumulator insurance, copy-bet features, boosted odds menus. The wider catalogue is the upside; the narrower framework is the cost.

The cost of the narrower framework

The narrower framework means: no New Zealand regulator, no New Zealand complaints route, no New Zealand harm-minimisation guarantee, no Inland Revenue backstop on payouts, no Gambling Helpline referral, no self-exclusion that applies across the New Zealand market. A punter who has self-excluded from TAB NZ and Betcha can still open an account on the offshore shelf and bet from it. The offshore shelf’s harm-minimisation tools are the operator’s own, and the operator’s tools are what they are.

The cost of a payment-method mismatch

No statutory payment rule for New Zealand betting accounts was found — card, bank, credit, prepaid, crypto are operator-level, not law-level. TAB NZ’s deposit methods are its own; an offshore brand’s deposit methods are its own. No payment-blocking order or bank obligation was found. Nothing states a rule on crypto or VPN use; account opening at TAB NZ requires a verified New Zealand address.

A punter using crypto on an offshore brand is using the payment method the offshore brand offers, on the framework the offshore brand sits in. The payment method is not the legal question; the legal question is the operator, and the operator’s lawfulness is settled by section 74AAA.

How the betting prohibitions extend

The Racing Industry Act 2020 section 74AAA covers racing betting, sports betting and other racing or sports betting — three categories the law names separately. The change took effect on 28 June 2025, and DIA told providers serving New Zealand to withdraw with immediate effect. Greyhound racing is closing in stages from 1 August 2026, and from that date offshore operators may not take bets on greyhound races either. The Online Casino Gambling Act 2026 licenses online casino gambling only and does not license sports betting — TAB New Zealand winning the right to apply for a casino licence does not extend the betting monopoly.

The penalty question

The penalty for breaching section 74AAA is not stated in the section; no prosecution of an offshore bookmaker was found. New Zealand does not block bookmaker sites. Section 19(4) of the Gambling Act 2003 (inserted in 2025) says an individual may not be convicted for placing a bet with an offshore betting operator in breach of section 74AAA. The point that holds: the operator carries the legal risk, the player carries the framework risk, and the punter’s choice is the one that decides which side they are on.

How a punter reads a price in practice

A punter who reads $1.90 as “slightly worse than 50/50” is reading the price at face value; the implied probability is 52.63%, and the price is below 50/50. A punter who reads $1.90 as “the operator’s edge plus the probability they have priced in” is reading the margin. The difference is one calculation: the reciprocal, and the gap between the sum of reciprocals and 100%.

Reading a single price

A single price is one number. The punter’s read is the implied probability, the operator’s edge, and the punter’s own estimate of the true probability. The three numbers together are the bet’s expected return. The math is not optional; it is what the price says.

Reading a market

A market is several prices on one event. The punter reads the sum of reciprocals, the gap to 100%, and the per-leg implied probability against their own estimate. The market a punter picks is a choice of margin, and the margin is the line between a stated price and a true probability.

Reading a multi

A multi is several markets combined into one bet. The punter reads the leg prices, the combined price, the compounded margin, and the correlation between the legs. A same-game multi has legs from one event; the correlation between the legs is the bookmaker’s pricing tool and the punter’s pricing tool. A multi across events has legs from independent events; the correlation between the legs is zero, and the compounding is the punter’s only pricing tool.

How TAB NZ and Betcha fit a punter’s catalogue

A punter who bets mostly on New Zealand racing — thoroughbred, harness, the Melbourne Cup, the Cup Day calendar — is on TAB NZ’s home ground. The racing catalogue is wide: Win, Place, Each Way, Quinella, Exacta, Trifecta, First Four, Double, Treble, Daily Double, Running Double, Quaddie, Big6, Same Race Multis, Place Extra. The pool dividends on the exotics are the New Zealand market’s speciality.

A punter who bets mostly on New Zealand and Australian sport — NRL, Super Rugby Pacific, All Blacks, the Black Caps, AFL — is on TAB NZ and Betcha’s shared ground. The sports catalogue is the one the apps lead with: head-to-head, line betting, total points, Same Game Multis on rugby and league matches, live betting on the bigger fixtures.

A punter who bets mostly on North American sport — NBA, NFL, MLB, NHL, the US college markets — is on the offshore shelf. TAB NZ covers the major North American leagues; the depth and the market variety is thinner than the offshore shelf’s. The depth is the gap; the offshore shelf is the place a North American sports punter reaches.

A punter who bets on esports is on the offshore shelf. Whether esports betting counts as “sports betting” under the Racing Industry Act is not settled; TAB NZ does not lead with esports; the offshore shelf does.

How a punter chooses the right path

The choice is between TAB NZ (TAB or Betcha, by surface) and the offshore shelf. The choice turns on three questions: what catalogue the punter wants, what framework the punter wants behind the catalogue, and what the punter is willing to give up.

Catalogue

TAB NZ’s catalogue is wide on New Zealand and Australian racing and sport, narrower on North American leagues and esports. The offshore shelf is wider on North American leagues and esports, narrower on New Zealand racing. A punter whose betting is mostly New Zealand racing and sport is on TAB NZ. A punter whose betting is mostly North American leagues or esports is on the offshore shelf. A punter whose betting straddles the two groups splits the difference, and the split is the catalogue cost.

Framework

TAB NZ’s framework is the New Zealand regulator, the New Zealand harm-minimisation tools, the Gambling Helpline, the Problem Gambling Levy. The offshore shelf’s framework is the operator’s own jurisdiction and the warnings DIA publishes. A punter who wants the New Zealand framework behind their bets is on TAB NZ. A punter who wants the wider catalogue and is willing to give up the New Zealand framework is on the offshore shelf.

The trade-off

The trade-off is catalogue against framework. TAB NZ’s narrower catalogue sits inside a wider framework; the offshore shelf’s wider catalogue sits inside a narrower framework. The punter who picks catalogue is paying for the gap with framework; the punter who picks framework is paying for the gap with catalogue. The choice is the punter’s; this page describes it.

A practical view of the calculation the page uses as a reference

The arithmetic on which the page leans is the margin on a two-way market. The illustrative example uses decimal odds of $1.90 / $1.90 — a symmetric bookmaker’s view of a 50/50 outcome. The implied probabilities are 1/1.90 on each side, summing to 105.26%; the payout share is 1/1.0526 = 95.00%; the margin is 1 – 95.00% = 5.00%.

The same shape, different prices: $1.85 / $1.85 gives an implied probability of 1/1.85 + 1/1.85 = 108.11%, a payout share of 92.50%, and a margin of 7.50%. $1.95 / $1.95 gives an implied probability of 102.56%, a payout share of 97.50%, and a margin of 2.50%. The narrower the spread on the two prices, the smaller the margin and the closer the bookmaker is paying out close to a “fair” 100%. The result on the page is stated as a band, not as a single figure, because the band is what holds across the range a punter actually meets: a market at $1.90 / $1.90 keeps around 5% on average, a market at $1.85 / $1.85 keeps around 7-8% on average, a market at $1.95 / $1.95 keeps around 2-3% on average.

The band serves as a reference for the margin that a market carries. It is not a quoted price; it is the shape that lets a punter read the price they meet on a real slip.

The punter’s checklist before they place a bet

A punter’s checklist, before they place a bet, is the question that turns the catalogue and the framework into a single decision. The question is not “which brand is best” — the question is “which path matches the punter’s situation.”

The path a New Zealand punter can walk

A punter whose betting is mostly New Zealand racing and sport, who wants the New Zealand framework behind their bets, and who is willing to give up the offshore catalogue is on TAB NZ. TAB or Betcha, by surface; the betting rules are the same. A punter who wants the racing heritage and the retail-outlet integration chooses TAB; a punter who wants the social framing and the daily Toolbox chooses Betcha. The choice between TAB and Betcha is a choice of surface, not a choice of operator.

A punter whose betting is mostly North American leagues or esports, who wants the wider catalogue, and who is willing to give up the New Zealand framework is on the offshore shelf. The brand on the shelf is the brand whose catalogue matches the punter’s sport and whose terms match the punter’s read on bonus conditions. The framework is offshore; the catalogue is wide.

A punter who straddles the two groups splits the catalogue across the two paths, with TAB NZ as the racing and Australasian-sport bookmaker and the offshore shelf as the North American and esports bookmaker. The split is the cost of straddling; the punter decides whether the split is worth the wider catalogue.

The single question the punter answers

The single question is: which path matches the punter’s situation. The catalogue and the framework are the inputs; the choice is the output; the audit is the terms the punter reads, the margin they pay, and the framework they sit in. The rest of the bet — the price, the stake, the multi, the cash-out — is the bet itself, and the punter reads the price the way the rest of this page has described.

Frequently asked questions

How do betting odds work?

A decimal odds figure is the multiple of the stake that comes back if the bet wins. A $10 stake at $2.10 returns $21, with $11 of net profit on top of the $10 stake. The stake is always returned alongside the net profit; that is the difference between decimal odds and the fractional odds written on British slips. The implied probability of a decimal price is the reciprocal: 1 divided by the odds. A punter reading odds as probabilities is reading them with the bookmaker’s margin still inside, and the margin is the gap between the sum of reciprocals across a market and 100%.

How does odds work with betting horse racing?

A Win bet pays if the selection finishes first. A Place bet pays if the selection finishes in the place positions the race declares, typically first, second and third in field sizes of eight or more. An Each Way bet is two bets of equal stake: one Win and one Place, with the stake doubled for the payout. Quinella pays on the first two finishers in either order. Trifecta pays on the first three in order. First Four pays on the first four in order. Doubles, Trebles, Quaddies and Big6 combine several races into one bet, with the dividend declared from a pool after the race settles. The odds on exotics are not a simple multiple — TAB NZ runs pool betting on the more popular exotic markets, and the dividend depends on the pool size and the number of winning units.

How do you bet at horse races with odds?

TAB NZ’s apps cover thoroughbred and harness racing pre-match and live, with Trackside live race streaming in the app alongside in-app betting. The app lists racing form, Blackbook and Jockey Challenge tools. A punter opens a TAB NZ account with a verified New Zealand address and ID, sets a deposit limit, and uses the bet types listed in the betting rules — Win, Place, Each Way, Quinella, Exacta, Trifecta, First Four, Double, Treble, Quaddie, Big6, Same Race Multis, Place Extra. Place Extra lets a punter back a runner to finish up to 10th in selected races. The age gate is 18, set by section 89 of the Racing Industry Act 2020; betting under 18 is an offence.

Which bookmaker may lawfully take sports and racing bets in New Zealand?

TAB NZ is the only provider lawfully offering racing and sports betting to people in New Zealand since 28 June 2025, under section 74AAA of the Racing Industry Act 2020. The two online brands of TAB NZ are TAB (tab.co.nz) and Betcha (betcha.co.nz); they are not rival bookmakers, they are the same operator group. There is no licence route for another bookmaker and no register of licensed bookmakers, because there is only one lawful provider. Offshore bookmakers that take bets from people in New Zealand are breaking section 74AAA on the operator side. The Department of Internal Affairs monitors compliance with the betting prohibition under section 92A of the Racing Industry Act 2020.

How is the return on a bet worked out from the stake and the odds?

A single bet’s return is the stake multiplied by the decimal odds. A $10 stake at $2.10 returns $21, with $11 of net profit on top of the $10 stake. The stake is always returned on top of the net profit. A combination bet’s return is the stake multiplied by the product of the leg prices; a three-leg multi at $1.50, $1.80 and $2.00 has a combined price of $5.40, and a $10 stake returns $54 with $44 of net profit if all three legs win. One losing leg voids the whole multi. The compounding is the punter’s upside on a multi; the compounding is also the margin compounding.

What is the bookmaker’s margin and how can it be seen in the odds?

The margin is the gap between the sum of the implied probabilities of every outcome in a market and 100%. A two-way market at $1.90 / $1.90 has implied probabilities of 52.63% on each side, summing to 105.26%; the gap from 100% is the margin, which is 5.00% on this market. The same calculation gives a 7.50% margin on $1.85 / $1.85, a 2.50% margin on $1.95 / $1.95, and a higher margin on a market with more outcomes. The margin is what the bookmaker keeps on every dollar bet on the market, on average across many bets. A punter reading the margin reads the gap between the stated price and the true probability; a punter reading the price alone reads the marketing line, not the bet.
