How playthrough works, how to calculate it, which NZ sites have the fairest terms, and practical tips for clearing bonus wagering faster.
Wagering requirements (also called playthrough requirements) are the number of times you must wager bonus money before it converts into real, withdrawable cash. They exist at every NZ online casino that offers bonuses, and they're the single most important factor in determining whether a bonus is genuinely worth claiming. I've seen countless Kiwi players sign up for a flashy "NZ$1,000 bonus!" without understanding that the wagering attached to it could make the bonus nearly worthless — or even a net negative compared to playing without a bonus at all.
Here's the core concept: when a casino gives you a bonus, they're not giving you free money. They're giving you playing credit that must be cycled through the casino's games a specified number of times. A "35x wagering requirement" means you must place bets totalling 35 times the bonus amount (and sometimes 35 times the bonus plus your deposit) before you can withdraw any winnings derived from that bonus. The casino profits because the house edge erodes your balance a little with each betting cycle, and by the time you've completed the wagering, the expected value of the remaining balance is less than the original bonus amount.
Understanding this mechanism doesn't mean bonuses are bad — it means you need to be strategic about which bonuses you claim and how you play through them. Over four years of reviewing NZ casinos from Mount Maunganui, I've cleared wagering requirements successfully dozens of times and converted bonus money into real withdrawals. The difference between success and failure almost always comes down to understanding the maths and choosing the right games for playthrough.
Lower wagering requirements are always better. A smaller bonus with 25x wagering will almost always produce better results than a larger bonus with 50x wagering. The multiplier matters more than the headline bonus amount in almost every scenario.
The calculation itself is straightforward, but there's an important distinction that trips up many players: whether the wagering applies to the bonus only, or to the bonus plus your deposit combined.
If the terms state the wagering applies to the "bonus amount," the calculation is simple:
Total wagering required = Bonus amount x Wagering multiplier
Example: You deposit $100, receive a $100 bonus (100% match), and the wagering is 35x on the bonus. Total wagering = $100 x 35 = $3,500. You need to place $3,500 worth of bets before you can withdraw.
Some casinos apply the wagering to both the bonus and the deposit combined:
Total wagering required = (Bonus + Deposit) x Wagering multiplier
Example: Same scenario — $100 deposit, $100 bonus, 35x wagering on bonus + deposit. Total wagering = ($100 + $100) x 35 = $7,000. That's double the playthrough for the same multiplier. This distinction is critical, and it's often buried in the fine print.
Watch Out: Always check whether the wagering applies to "bonus only" or "bonus + deposit." A 35x requirement on bonus + deposit is effectively the same as a 70x requirement on the bonus alone. Most NZ casinos apply wagering to the bonus only, but some (notably Spin Casino) apply it to both.
Let me walk through the actual maths for several NZ casinos I've reviewed, using their real bonus terms as of April 2026. These examples assume a $100 deposit and claiming the first-deposit bonus.
Jackpot City offers 100% up to $400 on your first deposit with 35x wagering on the bonus amount only.
In practice, you're expected to lose about $40 of the bonus to the house edge during wagering. But your deposit remains, and variance means you could easily finish ahead. This is a fair, achievable wagering requirement.
Spinjo offers a welcome package with 40x wagering on the bonus amount.
At 40x, the house edge consumes more than the entire bonus in expected terms. However, this calculation assumes perfectly average results. In reality, variance means roughly 35-40% of players will finish ahead after wagering, especially if they play high-volatility pokies where a single big hit can clear the requirement.
Spin Casino offers 100% up to $400 with 70x wagering on the bonus amount.
At 70x, the maths are brutal. You'd expect to lose $280 to the house edge while clearing the bonus — far more than the $100 bonus itself. In practice, this means the bonus actually costs you money unless you hit a significant lucky streak. I generally advise NZ players to skip bonuses with wagering above 50x and play with clean deposited funds instead.
Tip: Playing on a pokie with 98% RTP instead of 96% RTP cuts the house edge in half, from 4% to 2%. On a $4,000 wagering requirement, that's the difference between $160 and $80 in expected losses. Game selection during wagering is just as important as the wagering multiplier itself. See our high RTP pokies guide for the best options.
Here's how the major NZ-facing casinos compare on wagering requirements, using data from my own reviews and verified against their current terms as of April 2026:
| Casino | Wagering | Applied To | Time Limit | Max Bet During Wagering | Verdict |
|---|---|---|---|---|---|
| Jackpot City | 35x | Bonus only | 30 days | $5 | Excellent — fairest terms |
| Jonny Jackpot | 35x | Bonus only | 30 days | $5 | Excellent — tied best |
| Spinjo | 40x | Bonus only | 14 days | $7.50 | Good — reasonable terms |
| Roby Casino | 45x | Bonus only | 14 days | $5 | Average — slightly high |
| Spin Casino | 70x | Bonus only | 7 days | $5 | Poor — very hard to clear |
Jackpot City and Jonny Jackpot share the top spot with 35x wagering on the bonus only, combined with a generous 30-day time limit. These are the most player-friendly wagering terms I've found among major NZ-facing casinos. Spinjo's 40x is still within the reasonable range, though the shorter 14-day time limit means you need to be more disciplined about completing wagering promptly.
At the other end of the spectrum, Spin Casino's 70x wagering is the highest among the casinos I've reviewed and one of the toughest to clear profitably. The 7-day time limit compounds the problem — you're essentially forced to play intensively for a week to have any chance of completing the playthrough. For most NZ players, skipping the Spin Casino bonus entirely and depositing without a bonus is the smarter mathematical play.
For the most achievable bonus playthrough, Jackpot City at 35x is our top recommendation. The combination of low wagering, bonus-only application, generous time limit, and reasonable max bet restriction makes it the gold standard for NZ bonus terms. See our full bonuses guide for detailed comparisons.
Wagering requirements are the mechanism that determines whether a casino bonus actually adds value to your playing experience or quietly costs you money. Understanding the maths transforms you from a player who blindly claims every bonus into one who makes informed decisions about when to accept a bonus and when to play without one.
Every bonus has a theoretical break-even wagering multiplier — the point at which the expected value of the bonus becomes zero. For a 100% match bonus played on pokies with 96% RTP, the break-even point is approximately 25x. At 25x wagering, the house edge (4%) applied to your total wagers ($2,500 on a $100 bonus) equals $100 — exactly the bonus amount. Anything above 25x means you're theoretically losing more to the house edge during wagering than the bonus is worth.
This doesn't mean you should only play bonuses below 25x (they're extremely rare). It means you should understand that bonuses at 35-40x are already in negative expected-value territory but still achievable with variance on your side, while bonuses at 60x+ are almost certainly going to cost you money in the long run. Knowledge of the break-even point helps you set realistic expectations.
During the wagering period, your balance will fluctuate substantially as you place thousands of dollars in bets. A $100 bonus with 40x wagering means $4,000 in total bets — if you're betting $2 per spin, that's 2,000 spins. Your balance will swing up and down wildly during those 2,000 spins. Many players panic when their balance drops and either forfeit the bonus or make poor decisions. Understanding that this variance is normal and expected helps you stay disciplined throughout the process.
These strategies are based on what I've found works consistently across dozens of bonus-clearing sessions at NZ casinos:
The most impactful decision you can make during wagering is game selection. Blood Suckers (98% RTP), 1429 Uncharted Seas (98.5%), and Mega Joker (99%) minimise the amount your balance erodes during playthrough. Every percentage point of RTP retained during wagering is money that stays in your balance. Check our high RTP pokies guide for the full list of optimal wagering games.
Most casinos set a maximum bet size during wagering (usually $5-$7.50). Betting at this maximum clears the requirement faster — fewer total spins means less time for variance to erode your balance, and it reduces the risk of running out of time. Just make sure your bankroll can handle the swings at the higher bet level. If your bonus balance is $100 and the max bet is $5, you'll have significant variance over the 800 spins needed to clear 40x wagering.
While high-volatility pokies can produce exciting results during wagering, low-volatility high-RTP games (Blood Suckers, Starburst) provide the most predictable path to clearing requirements. Your balance will decline slowly and steadily rather than swinging wildly, which means you're less likely to bust before completing the wagering. If your goal is simply to clear the requirement and withdraw, low volatility is the safer approach.
Most NZ casinos display your wagering progress somewhere in the account or bonus section. Check it regularly so you know exactly how much more you need to wager. Some casinos show a percentage bar or a dollar figure of remaining wagering. If your casino doesn't display this, contact support and ask for an update.
If your balance drops during wagering, don't assume you've lost. The nature of pokies means a single bonus feature or big hit can restore and even exceed your starting balance. I've had wagering sessions where my balance dropped to $15 before a 150x hit brought it back to $225. As long as you have balance remaining and time on the clock, the wagering is still clearable.
Most casinos exclude certain games from wagering contributions entirely, or weight them below 100%. Table games typically contribute 10-20%, and some high-RTP pokies may be excluded. Playing an excluded game doesn't advance your wagering at all — you're just burning through your bonus balance for nothing. Always check the full list of contributing games before you start.
Tip: If a casino's bonus terms exclude Blood Suckers and other high-RTP pokies from wagering contributions, that's a strong signal that the bonus is designed to be hard to clear profitably. Consider declining the bonus and playing with your own funds instead.
After reviewing bonus terms at dozens of NZ-facing casinos, I've learned to spot the warning signs that indicate a bonus is designed to favour the house excessively. Here are the red flags to watch for:
Any wagering requirement above 50x makes it extremely difficult to convert bonus money into real withdrawals. The maths simply don't work in the player's favour at these levels. If the wagering is 60x, 70x, or higher, you're almost certainly better off declining the bonus.
A 3-day or 7-day wagering window forces you to play intensively, which isn't sustainable or enjoyable. It also increases the risk of not completing the wagering and losing everything. Look for casinos that offer 14-30 day windows.
As explained earlier, wagering applied to both the bonus and deposit effectively doubles the playthrough. A 35x bonus + deposit requirement is the same as a 70x bonus-only requirement in terms of total bets needed. Always clarify which calculation method applies.
A very low maximum bet during wagering means you need far more spins to complete the requirement, extending the time your balance is exposed to the house edge. A $1 max bet on $4,000 in wagering requires 4,000 spins minimum. Some casinos use this to make wagering feel interminable.
Some bonuses cap the amount you can withdraw after clearing wagering, regardless of your actual balance. If the max cashout is $200 and you clear wagering with a $500 balance, you only get $200. This cap effectively limits the upside of claiming the bonus while you bear all the downside risk during wagering.
If the bonus terms specifically exclude Blood Suckers, Mega Joker, 1429 Uncharted Seas, and other high-RTP titles from wagering contributions, the casino is deliberately preventing you from using the most mathematically efficient strategy. This is a clear signal that the bonus is stacked against you.
Important: If a bonus has three or more of these red flags, decline it. Playing with clean deposited funds (no bonus) gives you full control over your balance with no wagering requirements, no time limits, no game restrictions, and no withdrawal caps. Sometimes the best bonus is no bonus at all.

This doesn't mean you need to lose $3,500 — each bet counts toward the total regardless of whether it wins or loses.
Jackpot City and Jonny Jackpot are tied at 35x on the bonus amount only, which is the lowest among major NZ-facing casinos we've reviewed. Both also offer 30-day completion windows, making them the most player-friendly options.
No. Most casinos weight game contributions differently. Online pokies typically contribute 100%, but some high-RTP pokies may be excluded. Table games usually contribute 10-20%, and live dealer games may contribute even less or not at all. Always check the specific contribution rates in the bonus terms.
At most NZ casinos, you can forfeit your bonus and withdraw your remaining deposit at any time. However, doing so will void the bonus and any winnings from it. Some casinos deduct all bonus-related winnings when you forfeit, so check the terms carefully before making this decision.
If you don't clear the wagering requirement within the specified time limit (usually 7-30 days), both the remaining bonus balance and any winnings from it are forfeited. Your original deposit (if still available) is typically unaffected. Time management is crucial when accepting any bonus.
It depends on the wagering requirement. Bonuses with 35x or lower wagering add genuine value for most players. Between 35-45x, they're marginal but still worth claiming if you play strategically. Above 50x, you're generally better off declining the bonus and playing with clean deposited funds — no wagering, no restrictions, and full withdrawal access at any time.
Yes. Winnings from promotional free spins are almost always subject to wagering requirements, typically in the 35-50x range applied to the total winnings amount. In-game free spins triggered during regular play are not subject to additional wagering (unless you're already playing with bonus funds).
Most NZ casinos set a maximum bet of $5-$7.50 per spin during active wagering. Exceeding this limit can void your bonus and confiscate all winnings. Some casinos don't enforce this automatically but will review your play upon withdrawal request, so always stay within the stated limits.
