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% | 7.29% |
| Deposit ≥ 10% | 6.99% |
| Deposit ≥ 15% | 6.54% |
| Deposit ≥ 20% | 6.14% |
| Deposit ≥ 25% | 5.79% |
Higher deposit = lower LVR = better rate
About Fixed 5 Year
BNZ's 5-year fixed rate offers maximum certainty — five years of unchanging repayments regardless of where the OCR goes. With BNZ's cashback included, it's an option worth considering during periods when longer-term rates are priced attractively.
Historically, 5-year fixes tend to cost more than rolling shorter terms over the same period. But for borrowers who simply cannot tolerate payment variability — or who expect a sustained rate increase cycle — this term removes all guesswork.
