BNZ Mortgage Products

BNZ Classic (Floating) Standard floating rate mortgage with no break fees. Full prepayment flexibility. Suitable for those who want maximum flexibility or expect to make large extra repayments.

BNZ Fixed Rate Fixed for 6 months to 5 years. Standard break fee structure applies for early exit. BNZ allows 5% of original loan per year as extra repayments without break fees on fixed rate mortgages.

BNZ TotalMoney BNZ’s signature offset mortgage product — and one of the most comprehensive offset solutions in New Zealand. Links up to 10 BNZ accounts (savings, transaction, call accounts) against your mortgage principal for interest calculation.

BNZ Rapid Repay Fixed rate option that accelerates repayment by directing additional income to principal reduction. Suitable for borrowers who want a structured extra-repayment framework.

BNZ TotalMoney: Full Offset Account

Key features of BNZ TotalMoney:

  • 100% offset: Full balance of linked accounts offsets against mortgage principal
  • Multiple accounts: Up to 10 accounts can be linked
  • Fully transactional: No restrictions — withdraw from linked accounts freely
  • Linked account types: Transaction accounts, savings accounts, call accounts
  • Interest calculation: Daily on (mortgage principal − total linked balances)

How the benefit varies: The offset applies automatically to whatever balance is held in linked accounts, so the interest saved is larger when balances are high (for example, variable or lumpy cash flow held temporarily) and close to zero when balances are spent down.

See Offset Mortgage NZ for a full comparison of offset vs redraw.

Where to check the latest data

Rates, fees and returns change often. Before deciding, check current figures yourself:

  • interest.co.nz mortgage rates: tables of current floating and fixed home loan rates.
  • The provider's own website: has its current rates, fees and full terms; these change more often than any comparison page.
  • Financial Service Providers Register: shows whether a provider is registered to offer financial services in New Zealand.
