Every online casino in New Zealand offers deposit bonuses, promising players extra funds to spend on pokies, roulette, blackjack and more. But are these offers as generous as they seem? Under the surface, wagering requirements play a key role in determining how much a bonus actually costs.
It's a simple trade: the casino gives a player bonus money, and the player must spend a specified multiple of it - the "wagering requirement" - before withdrawing any of the bonus balance. A 20× bonus means the player has to wager 20 times the deposit and bonus. But that multiplier alone doesn't show the full picture of how much a bonus will cost.
At first glance, a 35× requirement appears huge. But does that mean a $100 bonus costs $3,500 to clear, or $7,000? The difference comes down to how the turn over is calculated. Bonus-only requirements, which many players assume, are far less costly than deposit-plus-bonus.
In practice, players' actual losses end up much higher than either of those figures. To work out the expected cost, multiply the total wagering by the house edge of the games played. A pokie machine with a 4% segment, typical for the casino online games that count most toward meeting wagering, would cost a player $140 to turn over a $100 bonus on a bonus-only offer at 35×. They lose $280 at the same wagering on a $100 deposit if that $100 bonus also counts.
Game weighting is the final multiplier that most players never factor in. Strip away even a portion from a game like blackjack, and you've added to the total wagering required. A 10% weighting on blackjack, not unusual, would make meeting a $100 bonus at 35× cost the player $3,500. They need to spend 10 times as much to clear the requirement.
The bottom line is that a bonus is not free money
Perhaps nowhere is the full cost of wagering clearer than when payments from operators keep people gambling who have promised themselves they will not. A 2025 study by Health New Zealand found that more than a third of the gamblers and more than half of the group of mixed gambler-free-to-play gamers resumed betting.
The experts have their own calculus. Introducing progression in paygaming in Australia starts with protecting the consumer, and that starts with understanding wagering requirements. For any buyer-client seeking to offer bonus payments to New Zealand customers, concluded one study, the only question to ask is: "What does this mean for the consumer?"
