Best High-Interest Savings Accounts in NZ (2025)

In a fluctuating economic environment, securing a high-interest savings account can be an effective way to preserve and grow your money. With interest rates changing frequently, it’s important to stay updated on the best options available in 2025. Below, we compare top New Zealand banks, interest rates, and bonus features to help you make a wise choice.

1. Comparing Major NZ Banks

In 2025, several banks are offering competitive rates for savings accounts. Typically, interest rates hover between 2.50% and 3.00% annually, but promotional offers and loyalty bonuses can push these rates higher.

2. Bonus Rate vs. Base Rate

Some accounts provide a base rate, plus a bonus rate if certain conditions are met—like maintaining a minimum balance or making no withdrawals. Always read the fine print to ensure you understand qualification requirements.

3. Fees and Account Conditions

Some high-interest accounts may charge monthly fees, which could eat into your gains. Look for fee-free options or ones where fees are waived if you maintain a set balance. Confirm whether you can withdraw funds without penalties.

4. Online-Only Banks and FinTechs

Beyond traditional banks, online-only institutions often offer superior rates because they have lower overhead costs. If you’re comfortable managing your finances digitally, these options can significantly boost your savings return.
