A prop bet – short for proposition bet – is a wager on something that happens within a match rather than on who wins it. Instead of backing a team to win or covering a handicap, you are betting on a specific event: whether a named player scores, how many runs a batter makes, or whether a game goes to extra time. Props have grown from a novelty attached to big events into a core part of most sportsbooks, and this guide explains what they are, the main types, how they are priced, and how they work for punters in New Zealand.
Key Points
- A prop bet (proposition bet) is a wager on a specific event within a match, not on who wins.
- Four broad groups: player, team, game/match and novelty/special props.
- Most props are priced as an over/under total or a yes/no binary, often near decimal odds of 1.90 each side.
- Prop margins are usually wider than main markets, so long-run value is harder to find.
- In New Zealand, TAB NZ is the only legal domestic operator for online sports and racing bets; you must be 18+.
What a prop bet actually is
In a standard market you bet on the result of the whole contest – the match winner (head-to-head), the handicap, or the total points scored. A proposition bet steps away from the final result and isolates a single occurrence that may or may not happen during play. The outcome of your prop can be completely separate from who wins: a player can score a try in a losing team, and a “yes” bet on that try still pays.
Because props sit outside the main result, they let you bet on the parts of a game you find most interesting or think you understand best, such as an individual’s form or a team’s scoring pattern. That same freedom is why there are often dozens of prop markets on a single fixture. If you are new to how prices and lines are set, it helps to first understand how sports betting works in New Zealand before adding props on top.
How prop bets are priced
Almost every prop is offered in one of two formats:
- Over/under (a total). The sportsbook sets a line – for example, a batter’s runs at 49.5 – and you bet whether the real figure will be over or under it. The half-point (the “.5”) removes the chance of an exact tie.
- Yes/no (a binary). A single event either happens or it does not – for example, “Will there be a try in the first 10 minutes?”
In New Zealand, prices are shown as decimal odds, where the number is your total return per $1 staked (including your stake). A two-way prop is often priced near 1.90 on each side. Two sides at 1.90 add up to more than a “fair” 50/50 market, and that extra slice is the bookmaker’s margin, sometimes called the overround – the built-in edge that lets the book profit over time. Props frequently carry a wider margin than main markets, so the same $10 bet gives you worse long-run value on a prop than on a head-to-head. If decimal pricing and lines are new to you, our guide to reading betting lines covers handicaps and totals in detail.
Prop Bet Types
| Type | What it covers | Example | Typical format |
|---|---|---|---|
| Player prop | One athlete’s performance | A named player to score a try; a batter over 49.5 runs | Yes/No or Over/Under |
| Team prop | One team’s output | Total team tries over 3.5; team to score first | Over/Under or Yes/No |
| Game / match prop | Events across the whole contest | First scoring play; match to go to extra time; total combined points | Over/Under or Yes/No |
| Novelty / special | Outcomes outside normal play | Coin toss; season award winner; ceremonial results at a final | Yes/No or multiple choice |
The main types of prop bets
Props are usually grouped into four broad families. The labels vary between sportsbooks, but the categories below cover almost everything you will see.
Player props
Player props are the most popular group. They track one athlete’s performance regardless of the result – a player to score a try at any time, a batter to make over 49.5 runs, a bowler to take the most wickets, or a footballer to have a shot on target. Try-scorer and top-scorer markets are player props, and they are central to rugby betting and most team sports. One caution worth knowing: there is usually far less public data on an individual’s output than on team results, so these markets can be harder to judge than they look.
Team props
Team props focus on one team’s output rather than the match result – total team tries over 3.5, which team scores first, or whether a side keeps a clean sheet. They are popular in cricket betting through markets such as a team’s total runs in the first six overs or the highest opening partnership.
Game and match props
Game props cover events across the whole contest without being tied to one competitor – the first scoring play, the total combined points, the method of the first score, or whether a match goes to extra time or a draw. In league, markets like the time of the first try or the winning margin band are game props, and they feature heavily in NRL betting.
Novelty and special props
Novelty props – often called specials – sit outside normal play and appear mostly around marquee events. Think the result of a coin toss, who wins a season award, or ceremonial outcomes at a final. These are essentially coin-flips with no reliable way to gain an edge, and the range offered depends on what the operator and regulator allow.
Prop bets and the New Zealand rules
Where you can place a sports prop in New Zealand changed in 2025. Under the Racing Industry Amendment Act 2025, which received Royal Assent on 27 June 2025, TAB NZ became the only legal domestic operator permitted to take online racing and sports bets from people in New Zealand, and offshore bookmakers are barred from accepting those bets. In practice that means legal sports props for Kiwi punters come through the TAB, which offers player-performance and match markets across rugby union, league, cricket and football, with depth that varies by sport and fixture.
A common point of confusion is the Online Casino Gambling Act 2026, which came into force on 1 May 2026 and set up a Department of Internal Affairs licensing regime for online casinos, phased towards full operation in 2027. That law covers online casino games – it does not change sports and racing betting, which stay under the racing and gambling legislation administered through the TAB.
Combining props: same-game multis
Many punters link several props from one fixture into a single bet, often called a same-game multi or bet builder – for example, a team to win plus a named player to score plus over a certain number of total points. Combining prices multiplies the potential return, but two things catch people out. First, player legs usually only stand if that player actually takes part in the match; if they are a late scratching, the rules set out how the leg is settled. Second, the outcomes are often correlated (a high-scoring game makes several “over” legs more likely at once), and sportsbooks price that correlation into the combined odds, which trims the value. Dead-heat rules can also reduce a payout when two players tie for a market such as top scorer.
Common mistakes to avoid
- Ignoring the margin. Props often carry a wider overround than main markets, so they cost more in the long run for the same stake.
- Over-trusting a hunch. Player props have less public data behind them, which makes them easy to misjudge and easy to over-bet.
- Treating novelty specials as skill. Coin tosses and ceremonial markets are pure chance – no research changes the odds.
- Chasing big multi payouts. Each extra leg lowers the real chance of the whole bet landing, even when the advertised return looks large.
- Skipping the market rules. Settlement, late-withdrawal and dead-heat terms differ by market and operator; read them before you stake.
None of these are solved by a “system” or tip – no betting approach can turn a negative-margin market into a reliable profit. A clear plan for stakes and record-keeping, covered in our guide to building a betting strategy, matters more than any individual pick.
Who prop bets suit
Props suit punters who follow a sport closely enough to have a view on individual players or scoring patterns, and who treat betting as paid entertainment rather than income. They are not a shortcut to winning: the wider margins and thinner data make them harder, not easier, than main markets. If you mainly want the simplest, best-value way to bet, head-to-head and handicap markets are usually the sharper choice, and keeping stakes small and using the available responsible gambling tools keeps props in the “for fun” column where they belong.

Frequently asked questions
What is a prop bet in simple terms?
A prop bet, or proposition bet, is a wager on a specific thing happening during a match rather than on the final result. Examples include a player scoring, a team’s total points going over a set line, or a game going to extra time. The outcome can be completely separate from who wins.
Are prop bets legal in New Zealand?
Yes, when placed with the legal domestic operator. Since the Racing Industry Amendment Act 2025, TAB NZ is the only operator allowed to take online sports and racing bets – including sports props – from people in New Zealand, and offshore bookmakers are barred from accepting those bets. You must be 18 or over.
What is the difference between a player prop and a game prop?
A player prop is about one athlete’s performance, such as a try-scorer or a batter’s run total. A game prop is about events across the whole contest, such as the first scoring play, the total combined points, or whether the match goes to extra time. Neither depends on the overall winner.
Why are prop bets harder to win than they look?
Props usually carry a wider bookmaker margin than main markets, so they offer poorer long-run value, and there is often less reliable data on an individual player than on team results. Novelty specials such as a coin toss are pure chance. Together these make props easy to misjudge.
Can you combine prop bets into one wager?
Yes. A same-game multi or bet builder links several props from one fixture into a single bet for a larger potential return. Be aware that each added leg lowers the chance of the whole bet landing, that correlated outcomes are priced in, and that a player leg generally only stands if that player takes part in the match.
