Rates by deposit sizeLVR — Loan-to-Value Ratio
The percentage of the property value you're borrowing. A lower LVR means a bigger deposit and usually a better interest rate.
Example: Property NZ$800k, deposit NZ$160k → LVR = 80% (borrow 80%, own 20%).
| Deposit < 5% | 7.44% |
| Deposit 5% – 9% | 7.14% |
| Deposit 10% – 14% | 6.69% |
| Deposit 15% – 19% | 6.29% |
| Deposit 20% – 24% | 5.94% |
| Deposit ≥ 25% | 5.94% |
Higher deposit = lower LVR = better rate
About Mortgage One
BNZ Mortgage One combines your home loan, transaction account, and savings into a single facility. Your income reduces the mortgage balance as soon as it's deposited, lowering the interest calculated daily — ideal for high-income earners who can keep the balance consistently low.
This all-in-one structure can save significant interest over time, but it requires disciplined financial management. The rate is higher than a standard fixed mortgage, so the real value depends on how effectively you channel cash flow through the account.
