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% | 6.09% |
| Deposit ≥ 10% | 5.79% |
| Deposit ≥ 15% | 5.34% |
| Deposit ≥ 20% | 4.94% |
| Deposit ≥ 25% | 4.59% |
Higher deposit = lower LVR = better rate
About Fixed 1 Year
BNZ's 1-year fixed mortgage is a competitive offering backed by one of New Zealand's strongest cashback incentives. It's well-suited to first-home buyers and refinancers looking for a sharp rate plus an upfront cash contribution toward moving costs or fit-out.
The 1-year term is New Zealand's most popular, and BNZ consistently prices this term aggressively. With the cashback, your effective first-year cost can be materially lower than the headline rate suggests — just be aware of clawback terms if you refinance away within a set period.
