What You Should Know About 400% Bonuses: Features & Tips
That “400%” number is eye-catching for a reason — it’s a huge bonus. But there are other important details to keep in mind:
- Bonus cap. There’s usually a maximum bonus amount, often NZ$800 or NZ$1,000.
- Wagering requirements. These can range from x30 to x60, so make sure you read the terms.
- Bonus validity. Most offers expire within 7 to 14 days.
- Betting limits. Some casinos restrict bets to around NZ$7.50 while a bonus is active.
Use these offers wisely — start with lower stakes to test the waters and focus on high-RTP slots to improve your chances of meeting wagering goals.
Something Extra to Consider
While the 400% casino bonus is definitely impressive, it’s not your only option. Some New Zealand casinos also offer 250% casino bonus or 300% casino bonus deals, which may come with easier wagering terms and lower overall risk. These offers are perfect for players who prefer a more balanced and steady approach to online gambling.
