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

BNZ TotalMoney is the most well-known offset mortgage in NZ. Key features:

  • 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)

Who it suits: Business owners, contractors, and anyone with variable or lumpy cash flow who naturally holds large balances at certain times. The offset works automatically — no action required.

Who it doesn’t suit: Borrowers who consistently spend up to their balance — the offset benefit requires you to maintain savings.

BNZ’s key differentiator over ANZ, ASB, and Westpac is the TotalMoney offset. If offset functionality is important to you, BNZ is typically the first bank to consider.

Negotiating with BNZ

  1. Compare with other banks first — bring a written competing offer
  2. Ask your mobile mortgage manager — BNZ’s MMMs typically have more rate flexibility than branch staff
  3. Mention TotalMoney — if you value the offset feature, use it as a negotiating point (you’re giving them more linked deposits)
  4. Use a broker — brokers often have wholesale rates and can compare BNZ vs all other major banks
