A decimal price of $2.10 looks like a clean number. It does not look like the commission a bookmaker keeps out of every dollar bet. A headline price of $3.50 on a roughie looks generous, until the other side of the same market comes in shorter than the tote dividend it is supposed to beat. The odds are the product. The margin is what sits inside it. This page works through both, from how a bet is built and settled to who is allowed to take one and what the return on a winning bet works out to. The frame is New Zealand, where the list of who can lawfully offer a price has been one name long since 28 June 2025.

Since an amendment to the Racing Industry Act 2020 took effect on 28 June 2025, TAB NZ and its online sister brand Betcha are the only operators allowed to take online sports and racing bets in New Zealand.

October 30, 2026 · verified against the Racing Industry Act 2020, section 74AAA (in force 28 June 2025) and the Department of Internal Affairs’ guidance on the offshore prohibition.

How a price becomes a bet: the mechanics of odds and stake

A decimal odds figure is the total return for every $1 staked, including the stake itself. Stake $10 at $2.10 returns $21 if the bet wins: the $10 stake and $11 of profit. That arithmetic is the whole of the payout formula and it never varies, win or lose, multi or single. What varies is the payout share: across the outcomes of one market, the bookmaker sets prices such that the implied probabilities sum to more than 100%. The gap between that sum and 100% is the margin, and it is what the bookmaker keeps of every unit bet.

Reading a single price

A decimal price of $2.10 implies a 47.6% chance of the runner or selection winning (1 ÷ 2.10). That is what the market says the outcome is worth if the bookmaker took no cut. A price of $1.40 implies 71.4%. The shorter the price, the heavier the favourite the bookmaker says the selection is. A price above $10 implies something the firm expects to happen less than once in ten.

On a TAB NZ bet slip, the decimal price sits beside the selection. Underneath, the stake field turns a number into the wager. When the bet settles, the return — not the profit — is what the punter collects. Profit is the return minus the stake. A punter who backs a $5 winner at $4.00 collects $20, of which $15 is profit; the $5 stake came back with it.

Building a multi

A multi (accumulator, parlay) is several legs joined into one bet. The odds multiply: a three-leg multi at $2.00, $3.00 and $1.50 returns $9.00 for a $1 stake (2 × 3 × 1.5). All legs must win or the multi loses, except where TAB NZ’s rules say a leg becomes void (a scratchings rule on racing, for example): a void leg drops out and the multi continues on whatever legs remain.

A Same Game Multi, or SGM, takes every leg from one event — the result, a player to score, the total points. The legs still multiply into one price. The trade is correlation: the legs of a same-game multi are not independent the way a multi spread across fixtures is, and the bookmaker builds that into the price. Punters reading same-game multis treat the multiplied price as the firm’s full quote on the combined outcome, not as the product of three independent quotes.

Cash out and place extra

TAB NZ’s app lets punters lock in a win or cut a loss before the event settles. The cash-out figure is the firm’s live quote on the bet at that moment, and is generally lower than the expected return because the firm is buying the bet off the punter mid-flight. Place Extra extends the standard Place market (first, second or third, depending on field size) to a finish further down the field — up to tenth in selected races. The price shortens accordingly; the rule that matters is the finishing position the punter is asking for.

What the margin does to a price

Take an illustrative two-way market priced $1.90 / $1.90. The implied probabilities are 52.6% and 52.6%, summing to 105.3%. The payout share is the reciprocal: 1 ÷ 1.053 = 95.0% of every dollar staked across the market. The margin — what the bookmaker keeps — is 1 minus 95.0%, which is 5.0%. That gap is the firm’s gross margin on the market before costs and before any deduction for promotional offers.

A more competitive two-way market might come in at $1.95 / $1.95. The implied probabilities sum to 102.6%, the payout share lifts to 97.5%, and the margin falls to 2.5%. A longshot-heavy market, where prices spread from $1.40 to $5.00 across the field, has a payout share closer to 90% and a margin near 10%. The trade the punter is making with the bookmaker is the margin: every dollar staked across all outcomes, the firm expects to keep a share of it. A market with a margin of 5% is a 5% tax on the punter’s turnover, paid before the bet is even placed.

For a multi, the margins of each leg multiply in their effect on the combined price. Two legs at 5% margin compound to roughly 9.75% margin on the multi. Four legs at 5% compound to roughly 18.5%. The longer the multi, the more the margin eats into the headline price, which is why a high-multi “boom or bust” punt is largely a margin play dressed as a selection play.

The arithmetic the page cares about

The result of the worked example is a band, not a single figure: on a two-way market at $1.90 / $1.90, the bookmaker’s margin sits around 5%, with a payout share to punters of roughly 95%. The condition that holds it there is that the example uses equal prices; a market where one side is $1.30 and the other is $3.50 sits at a lower payout share and a higher margin, because the short price carries more of the implied probability than the longshot does. Pinning this to a single number misrepresents the way margins in real markets move with the price spread.

What changes from one bookmaker to another: ranking the comparison set

Ten brands sit on the comparison set. They do not sit on the same field. TAB and Betcha are the two online brands of TAB NZ, the only operator lawfully offering racing and sports bets to people in New Zealand since 28 June 2025. The other eight are overseas brands punters encounter through offshore channels: none of them holds a New Zealand licence, and section 74AAA of the Racing Industry Act 2020 puts the operator, not the punter, on the wrong side of the law for serving a New Zealand resident. Reading them on a New Zealand betting guide is not the same as being able to bet with them from a New Zealand address; the table below is the comparison set, not a sign-up shortlist.

The reviewed bookmakers differ on the bet types they carry, the markets they price, the formats they show odds in and the safer-gambling tools they list. TAB NZ covers horse and harness racing, rugby union and rugby league and other sports, pre-match and live, with same-race multis and same-game multis built into the app and Place Extra extending place-finish positions in selected races. Betcha sits alongside TAB NZ on the legal side and adds a daily Toolbox of odds boosts and insurance tools, a Bet Social section where punters chat and follow tipsters, and a Playbook of match analysis. The offshore brands vary widely: some show decimal odds in six formats, some offer cash out with partial cash out, some carry accumulators and bet builders, a smaller number carry a bet-settlement feature such as boosted odds or copy bets.

A column that lists the firm’s own licence number is not printed because licence authority alone already sits in the second column. The audited point that varies from row to row is the bet-type menu: TAB NZ carries a racing-rich set few offshore brands can match, and Betcha layers community features on top of the same prices. The offshore brands spread more thinly across formats and features, and that is where the difference lives.

Who may take a bet in New Zealand

The frame. Since 28 June 2025, section 74AAA of the Racing Industry Act 2020 states 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 person is resident or incorporated. The Department of Internal Affairs, which monitors compliance, told providers serving New Zealand to withdraw with immediate effect when the section came into force. There is no licence to apply for and no licence register for bookmakers, because there is only one lawful provider. The law does not geo-block offshore websites; it puts liability on the offshore operator that chooses to keep serving New Zealand addresses.

TAB NZ runs as two online brands: TAB and Betcha. They are not rivals and they are not bookmakers a punter chooses between on price; they are two storefronts of the same operator, with different product focuses. The TAB app is the older and broader package, racing-rich and sport-rich, with multi-day and same-game multis, Place Extra, trackside live streaming and a list of safer-gambling tools. Betcha sits on the same lawful base and adds a community layer: a daily Toolbox of odds boosts and insurance on bets that miss, a Bet Social feed where punters chat and follow tipsters, and a Playbook of match previews and tips. Both carry New Zealand harm-minimisation features; both stay under the same complaints framework.

The partner running the technology. Under a 25-year agreement signed in 2023, Entain operates the TAB business in partnership with TAB NZ. The deal gives Entain a 50/50 share of gross profits, with at least NZ$150m a year going to TAB NZ for the first five years, and Entain pledged a one-off payment of NZ$100m to the racing sector. The agreement does not change who takes bets from a New Zealand punter — it changes who builds and runs the platform behind the counter.

Where the offshore brands sit. Since 28 June 2025, an overseas bookmaker taking sports or racing bets from a person in New Zealand is breaking New Zealand law. The Department of Internal Affairs’ stated position warns that overseas operators may be in jurisdictions with minimal consumer safeguards, may not return unspent credits and may not pay out large wins. New Zealand does not block bookmaker sites. A punter is not established by any source to face conviction for placing a bet with an offshore operator: 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; no source states a player penalty. The safe wording for any reader is: TAB NZ and Betcha are the only lawful option; offshore is unlawful for the operator, no New Zealand complaints route reaches it, and the Department of Internal Affairs has flagged the risks in writing.

A note on the casino question

The Online Casino Gambling Act 2026 licenses online casino gambling in New Zealand. TAB NZ won the right to apply for an online casino licence. That licence does not extend the betting monopoly: the casino permit and the betting monopoly are separate regimes under separate statutes. Anyone describing TAB NZ’s casino licence as evidence that other sports and racing bookmakers may apply for a New Zealand betting permit is reading one statute as the other.

A note on greyhound racing

Greyhound racing is closing in stages from 1 August 2026, and from that date offshore operators may not take bets on greyhound races either, because the underlying racing product no longer exists in New Zealand. For a punter, the change removes a racing code entirely from the menu and shifts interest toward harness and thoroughbred racing for the same kind of bet structure.

What a New Zealand bettor can do to manage the risk

New Zealand gambling law puts the weight of harm-minimisation on operators it licenses — and TAB NZ is the only one in this market. The Department of Internal Affairs holds TAB NZ to the requirement to keep the risks of problem and underage gambling minimised. The framework that reaches the punter is the one TAB NZ publishes, plus the free national services that any New Zealand gambler can use.

The tools TAB NZ lists

TAB NZ provides safer-gambling tools in its app: deposit limits, time-outs and self-exclusion. A deposit limit caps what the punter can load into the wallet over a day, week or month; a time-out suspends the account for a chosen period; a self-exclusion closes it for longer, with conditions on re-entry. The exclusion applies across TAB NZ’s brands: TAB and Betcha read from the same account. New customers can receive bonus cash that can be split across multiple bets, and the app lists a Mega Multi bonus of up to NZ$50 in bonus cash when a multi of four or more legs falls short by a set number of legs; the terms on that promo are TAB NZ’s own, and a punter reading it reads those terms before claiming.

The national help lines

The free Gambling Helpline — 0800 654 655, with a text line at 8006 — and Safer Gambling Aotearoa are the national services any New Zealand gambler can call. The helpline is not a TAB NZ service; it is the free national route. A punter dealing with the urge to chase a loss, a bet schedule that is no longer recreational or a household impact has a free line to call at any hour.

Age and identity

The age for TAB NZ betting is 18. The TAB NZ app’s App Store age rating is 17+, but the app’s own statement is that customers must be 18 or over to bet. Betting under 18 is an offence under section 89 of the Racing Industry Act 2020. A TAB NZ account needs a verified New Zealand address and ID — a punt can be refused or the account closed if the verification fails. Land-based casinos in New Zealand are 20; that is a separate permit regime and does not apply to TAB NZ’s sports and racing product. The rule that matters at the counter is the betting age: 18.

Tax

For the punter, Inland Revenue guidance says recreational gambling winnings are generally not taxable and prize money from TAB horse, dog and trotting races is not taxable. A person who bets as a business is a different case. The page describes this as Inland Revenue’s published position, not as tax advice — anyone with gambling income approaching business levels consults Inland Revenue or an accountant. Operator-side, TAB NZ pays the Problem Gambling Levy (0.74% of gambling spend, in force from 1 July 2025 to 30 June 2028); overseas operators supplying New Zealand residents pay online gambling duty (12% of profits since 1 July 2024, 16% from 1 January 2027). Payment of duty does not make an offshore offer lawful in New Zealand. The point-of-consumption charge on offshore racing and sports bets ceased on 30 June 2026.

The operators in detail

Each operator below gets the same treatment: what the firm offers on odds and bet types, what its own terms state about the New Zealand position, and where the firm sits for a punter weighing up the comparison set. The New Zealand wagering regime is the single most important line in every block — TAB NZ and Betcha are the only lawful options, and the offshore brands sit where they sit on the law.

TAB

TAB is the online flagship of TAB NZ, the monopoly sports and racing bookmaker for New Zealand since 28 June 2025. The app covers horse and harness racing, rugby union and rugby league, and a broader menu of other sports, pre-match and live. TAB’s bet-type list is the broadest on the comparison set: Win, Place, Each Way, Quinella, Exacta, Trifecta, First4, Double, Treble, Quaddie and Big6 on racing; Same Race Multis, Same Game Multis and one-tap Popular Multis on the multi side; Place Extra extending place-finish positions up to tenth in selected races. Trackside live race streaming with in-app betting sits inside the app, alongside racing form, Blackbook and Jockey Challenge tools, and a simplified wallet for deposits and withdrawals.

The numbers that matter for a punter weighing TAB against the rest of the set are the licence and the menu. The licence is one of two online brands of TAB NZ, the only operator lawfully offering racing and sports betting to New Zealand residents. The menu is wider than any offshore brand on the comparison set because the racing product in TAB NZ’s terms is built for the New Zealand codes — thoroughbred, harness, greyhound (until 1 August 2026). The safer-gambling tools — deposit limits, time-outs and self-exclusion — sit inside the app and apply across the brand. TAB NZ publishes its betting app under the seller name New Zealand Racing Board; the app first released on 8 September 2014.

The verdict. TAB is the brand for a New Zealand punter who wants the full racing and sports menu under a New Zealand licence, with harm-minimisation tools built into the app and a complaints framework under the Department of Internal Affairs. The trade for the breadth of the menu is that no offshore brand on this comparison set can take a New Zealand punter’s bet lawfully, so breadth is not the only axis TAB wins on — legality is.

Betcha

Betcha is the second of TAB NZ’s two online brands, launched on the same legal base. The product face is younger and community-led than TAB’s: a daily Toolbox with odds boosts and insurance tools for bets that do not land, a Bet Social section where punters chat, follow tipsters and share bets or pools, and a Playbook with match previews and tips. The bet types beneath the surface are the TAB NZ bet types — fixed-odds, multis, racing — built on the same settlement engine. A punter using Betcha is betting with TAB NZ; the wallet and exclusion regime sit under the same TAB NZ account.

The verdict. Betcha is the brand for a New Zealand punter who wants TAB NZ’s prices with a community layer, odds-boost tools and insurance on the legs that lose. The trade against TAB is that the racing-heavy product, the live racing streams and the established multi-day multi package all sit a click away on the same operator. The bettor who picks Betcha picks it for the product surface, not the licence — the licence is shared.

Thunderpick

Thunderpick operates under a Curaçao licence (OGL/2024/677/0722), with the holder Paloma Media B.V. carrying Curaçao company number 146988. The platform is a crypto-led sportsbook focused on esports, with a casino alongside. Curaçao gives no local legal standing; under section 74AAA of the Racing Industry Act 2020, Thunderpick is on the wrong side of the law if it serves a New Zealand address. The Department of Internal Affairs’ stated risks apply: minimal consumer safeguards in some offshore jurisdictions, possible refusal to return unspent credits, possible refusal to pay out large wins, and no New Zealand complaints route reaching the platform.

The verdict. Thunderpick is the platform for a crypto-comfortable bettor using a non-New Zealand address who values the esports-focused menu. Because the licence does not apply here and the New Zealand betting monopoly bars it from taking local bets, the Department of Internal Affairs flags this as an offshore risk.

Rooster

Rooster is operated by Novatrix SRL, incorporated in Costa Rica (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 shows odds in six formats. Tobique is not a New Zealand licence.

The verdict. Rooster is the option for a bettor who prefers a sportsbook with a built-in Predictions section. This platform holds no New Zealand licence and does not reach the local complaints framework.

Winz

Winz’s footer states the operator holds licences delivered by Anjouan and Tobique. Beyond that, the terms describe an operator-level product. Neither licence permits taking local bets under section 74AAA, and the New Zealand complaints framework does not reach the platform.

The verdict. Winz is the choice for a bettor comfortable with an Anjouan-and-Tobique licensed platform. As with the other offshore brands, the licence provides no local coverage.

BetAlright

BetAlright’s home page states that the brand accepts customers over 18 years of age only and runs a separate partners site at partnersbetalright.com. The site names no licence that applies in New Zealand; the brand sits outside the New Zealand framework under section 74AAA.

The verdict. BetAlright is the choice for a bettor where an 18+ gate is the primary regulatory anchor. The operator holds no local licence and is outside the local complaints framework.

Sportaza

Sportaza names an Anjouan licence (ALSI-202606064-FI2) in its terms. The sportsbook offers cash out before an event or market is finalised, a Bet Builder where a void selection voids the whole slip, multiples, Asian lines and interval markets in 1, 5, 10 or 15 minute ranges. Anjouan permits no local wagering.

The verdict. Sportaza is the choice for a bettor who wants Asian lines, interval markets and a Bet Builder with explicit voiding rules. No local licence or complaints route exists for this operator.

FunBet

FunBet’s home page describes a sportsbook offering odds on football, ice hockey, American football, basketball, volleyball, tennis, rugby and baseball, with live betting and a sportsbook described as open 24/7. The site names no licence that applies in New Zealand, and the platform offers accumulators and bet builders at the operator-level product. New Zealand does not licence the brand under section 74AAA.

The verdict. FunBet is the option for a bettor who wants a 24/7 multi-sport sportsbook with accumulators and bet builders. The licence framework does not apply here and the operator’s bets fall outside the local complaints protections.

BillyBets

BillyBets offers three odds formats — Decimal (2.00), American (+100) and Fractional (1/1) — and a sports product with cashback and reload bonuses on sports, a coin shop where coins earned through depositing, betting, tournaments and challenges are exchanged for free bets and free spins, and a five-tier VIP programme. The site names no licence that applies in New Zealand.

The verdict. BillyBets is the option for a bettor who wants a multi-format odds display and a coin-shop loyalty programme. These mechanics carry value only at an operator on the lawful side of the local regime, which BillyBets is not.

BetNinja

BetNinja’s home page states that the platform is licensed to conduct online gaming operations by the Union of the Comoros. The licence is not recognised in New Zealand, and the local complaints framework does not reach the brand.

The verdict. BetNinja is the option for a bettor comfortable with a Comoros-licensed platform. No local licence or complaints route exists, and the Department of Internal Affairs has issued warnings about the risks.

What the odds tell a New Zealand punter, in practice

A punter choosing where to place a bet in New Zealand has the narrowest legal choice of any reader of a sports-betting guide — TAB NZ or Betcha, both under the same licence. The deeper choice is what to do with the price once it is set.

The trade against the offshore set is not really a trade. TAB NZ’s bet-types menu, same-race and same-game multis, Trackside live racing stream and the New Zealand harm-minimisation tools are not features an offshore brand can match for a New Zealand punter. They are the only legally available features. The trade the punter actually makes is with the margin built into every price.

Reading the price the right way

The punter who reads a $2.10 price as a 47.6% chance of winning is reading it correctly, and missing what matters. What matters is the margin on the market. A two-way market at equal prices of $1.90 keeps about 5% of every dollar staked across outcomes. A punter punting $100 on the result and getting it right takes $190 back; the market over the long run pays out $95 of every $100 staked, $5 retained. That is the firm’s take before costs.

A multi compounds the effect. Four legs at a 5% margin per market compounds to roughly 18.5% margin on the combined price. A punter backing a four-leg multi at a headline price of $20 has a compounded-margin headwind the headline price does not show. The dollar return is the dollar return, but the chance of clearing the leg set is what the margin takes.

What the bonus terms cost

TAB NZ’s new-customer bonus cash is split across multiple bets and the app lists a Mega Multi bonus of up to NZ$50 in bonus cash when a multi of four or more legs falls short by a set number of legs. The headline is the dollar amount. The terms behind it are TAB NZ’s own, and a punter claiming it reads the conditions on minimum odds, eligible markets and any deadline before the bonus expires. Betcha’s Toolbox with odds boosts and insurance tools carries the same trade: a boosted price or an insurance leg is a marketing number dressed as a price change, and the conditions on it determine what it actually pays.

The arithmetic is the same across the comparison set. A boosted price is a discounted bet if the conditions swallow the discount. An insurance tool is a free-bet at the back end if the leg misses. Neither is “free” — both are the firm’s marketing expressed in price terms. The punter who reads the small print and treats the boosted price the same way they treat the unboosted price reads it right.

The two genuine levers a New Zealand punter has

The first lever is choosing which market to play. A two-way market with prices close to $1.95 / $1.95 is a low-margin market. A longshot-heavy market with prices spread from $1.40 to $5.00 is a high-margin market. The punter’s preference for short-priced favourites or longshots does not change the margin; the market’s structure does.

The second lever is the length of the multi. A single bet carries the market’s margin. A multi compounds the markets’ margins. The punter’s appetite for the multiplied payout does not change the compounded take. A two-leg multi at 5% per leg is roughly 9.75% margin. A three-leg multi is roughly 14.3%. The numbers are arithmetic, not opinion.

What TAB NZ’s licence gives

TAB NZ accounts are under the Department of Internal Affairs’ monitoring regime, the Problem Gambling Levy funds harm-minimisation services, and a self-exclusion applies across both TAB NZ brands. A punter who sets a deposit limit at TAB NZ has that limit applied across TAB and Betcha. A punter who self-excludes at TAB NZ is excluded from Betcha as well. A punt at an offshore brand carries none of these mechanisms — the offshore firm has its own terms, and the New Zealand framework does not reach them.

The frame that recurs through the comparison set is the divide between what is lawful and what is available. TAB NZ is the only lawfully available sports and racing bookmaker in New Zealand. The offshore brands are available through offshore channels, with the law on the operator’s side and the Department of Internal Affairs’ warnings on the punter’s. The choice is not between two equivalent menus; it is between one menu with full harm-minimisation and others with none.

The betting market in plain terms

The market for sports and racing betting in New Zealand is a single desk. The desk’s prices carry a margin that ranges from roughly 2.5% on a competitive two-way market to roughly 10% on longshot-heavy markets and north of 18% on a long multi. The desk’s safer-gambling tools are inside the app: deposit limits, time-outs and self-exclusion. The desk’s complaints route is the Department of Internal Affairs. The desk’s identity checks are real: a verified New Zealand address and ID are required to open an account. The desk’s age rule is 18 for betting, 20 for casinos.

The punter reading a price under that desk is reading a number with three things already built into it: the firm’s margin, the firm’s view of the outcome’s chance, and the firm’s price for the risk it is taking on. The punter who reads only the headline price reads a third of what is on the page. The punter who reads the price, the margin and the small print reads the full product.

The offshore brands sit at the desk next door. Their prices carry the same kind of margin. Their safer-gambling tools carry the same kind of function. Their identity checks operate under their own jurisdiction. Their age rule is the same 18+ the operator publishes. None of this converts the licence into a New Zealand licence, and none of it converts the Department of Internal Affairs’ warnings into reassurance. A New Zealand punter using a New Zealand address is on the wrong side of section 74AAA of the Racing Industry Act 2020 if the offshore brand takes the bet, and the Department of Internal Affairs has told those brands to withdraw.

What the page has established

The mechanics of odds and stake are settled on the first three sections. The comparison set is laid out by licence status and what each brand’s terms state on bet types, in the table and the operator write-ups. The legal frame is one name since 28 June 2025, with Entain running the platform under a 25-year partnership that keeps at least NZ$150m a year flowing to TAB NZ for five years. The safer-gambling and identity frame is the TAB NZ app’s deposit limits, time-outs and self-exclusion, the 18+ age rule and the verified New Zealand address, with the Gambling Helpline (0800 654 655, text 8006) and Safer Gambling Aotearoa as the national support routes. The arithmetic — the book’s margin inside every price — is the page’s gain in understanding, and the compounded margin of a multi is what a punter carries when a single bet is dressed as a four-leg special.

Frequently Asked Questions

How do betting odds work?

A decimal odds figure is the total return for every $1 staked, including the stake. Stake $10 at $2.10 returns $21 if the bet wins: $10 stake plus $11 of profit. The price implies a probability — $2.10 implies 47.6%. Across all outcomes of a market, the implied probabilities sum to more than 100%; the excess is the bookmaker’s margin. A two-way market at $1.90 / $1.90 has a payout share of roughly 95% and a margin of roughly 5%.

How does odds work with betting horse racing?

The basic bet types on racing are the same arithmetic — decimal odds, stake multiplied by odds — and the bet-types menu widens out: Win, Place, Each Way, Quinella, Exacta, Trifecta, First4, Double, Treble, Quaddie and Big6. Exotics combine the runners and finishing positions; the odds on a quinella or trifecta are the compounded prices of the runner combinations, with the margin the firm builds into those combinations. TAB NZ publishes the rules on each bet type in its betting rules; the punter who wants the full arithmetic reads those rules before staking.

How to bet at horse races odds?

The price on the runner is the total return for every $1 staked: $4.00 returns $4 for a $1 stake, $3 of profit on top. The stake field on the bet slip turns the wager into the punter’s chosen dollar amount. Punters who want a finish position outside the standard Place market use Place Extra, which extends the place finish up to tenth in selected races. The punter’s return on a winning Place Extra bet is the dividend the firm declares at settlement.

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

TAB NZ may, through its two online brands TAB and Betcha. Section 74AAA of the Racing Industry Act 2020, in force since 28 June 2025, makes TAB NZ the sole lawful provider of racing and sports betting to people in New Zealand. There is no licence to apply for and no register of bookmakers, because there is only one lawful provider. The Department of Internal Affairs told unlicensed providers to withdraw with immediate effect.

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

Return = stake × decimal odds; net profit = stake × (decimal odds minus 1). For a multi, the odds of each leg multiply into one combined price. For a same-game multi, the legs come from one event and the prices multiply the same way — the difference is in the selection, not the arithmetic. A bet placed at $10 stake and $4.50 decimal odds returns $45, of which $35 is net profit.
