Quick answer
A wagering requirement tells you how much you must stake before withdrawing bonus winnings. Multiply the bonus by the multiplier to get the total staking required. A NZ$100 bonus at 40x means NZ$4,000 of staking, which at 96% RTP carries an expected cost of about NZ$160 — more than the bonus itself.
The five numbers that decide everything
Ignore the headline amount. These are the terms that matter:
- Wagering multiplier — and what it applies to.
- Maximum bet while wagering — breach it and the bonus and its winnings usually go.
- Expiry window — how long you have to complete wagering.
- Maximum win cap — the total the bonus can ever pay.
- Game weighting — how much each game type contributes.
Doing the maths
The formula is simple:
required staking = bonus amount x wagering multiplier
Then estimate the cost at the game's RTP:
expected cost = required staking x house edge
| Bonus | Multiplier | Required staking | Expected cost at 96% RTP | Verdict |
|---|---|---|---|---|
| NZ$50 | 30x | NZ$1,500 | NZ$60 | Close to break-even, plausible |
| NZ$100 | 40x | NZ$4,000 | NZ$160 | Bonus is worth less than the cost |
| NZ$200 | 50x | NZ$10,000 | NZ$400 | Only worth it at very low volatility |
| NZ$3,000 (max) | 50x | NZ$150,000 | NZ$6,000 | Effectively unattainable for most players |
Two conclusions follow immediately.
First, the headline total is marketing. A "up to NZ$22,500 plus 350 spins" package spread across four deposits with a 50x multiplier asks you to stake NZ$1.1 million to clear the whole thing. Nobody does that. What you actually experience is the first deposit.
Second, a smaller bonus with fairer terms is worth more. A NZ$50 bonus at 30x with 30 days to clear and no win cap is a better offer than NZ$3,000 at 50x with a 7-day window and a 10x cap.
The maximum-bet trap
Almost every bonus restricts how much you can stake per spin while wagering. Reported caps around NZ$5 and NZ$7.50 are common. Exceeding the cap typically voids the bonus and any winnings from it.
This catches players who do the sensible thing — raise their stake to clear the requirement faster. It does not work that way. If you raise your stake above the cap, you usually lose everything.
Expiry windows
Seven days is standard. Some brands use a three-day window, which is genuinely tight if you have a job. If you cannot realistically play within the window, skip the bonus and deposit without it — your money then has no strings attached at all.
Maximum-win caps
Some offers cap total winnings from bonus funds, often around 10x the bonus. That means a NZ$3,000 bonus can never pay more than about NZ$30,000 from bonus play, no matter what happens. Caps are legal and disclosed in the terms, but they change the value of the offer substantially.
Game weighting
| Game type | Typical contribution |
|---|---|
| Slots (most) | 100% |
| Some slots, depending on the operator's exclusions | Reduced or excluded |
| Live dealer tables | 10% or less |
| Roulette and blackjack | Often 0–10% |
| Video poker | Usually excluded |
If live dealer is what you want to play and it counts 10%, a NZ$100 bonus at 40x requires NZ$40,000 of live staking. That is not a realistic target. Read the weighting table first.
When to take a bonus and when to decline
Take it if:
- you were depositing that amount anyway
- the multiplier is 30–40x with at least 7 days, preferably 30
- there is no maximum-win cap
- you enjoy slots rather than live tables
Decline it if:
- the multiplier is 50x or more with a short window
- there is a low maximum-win cap
- the terms require live games to clear it
- you wanted to withdraw quickly
A bonus you cannot clear is worse than no bonus, because it locks your own deposit behind the same terms.
A quick reality check for NZ players
Every operator we review runs a multi-deposit welcome package with a large headline number. That is the format now. The useful comparison is not the total, it is the first-deposit terms: how much you have to stake, whether there is a cap, and how long you have. Read those three lines and you will know more about the offer than 95% of players who click the button.
