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% | 7.64% |
| Deposit ≥ 10% | 7.39% |
| Deposit ≥ 15% | 6.64% |
| Deposit ≥ 20% | 6.14% |
Higher deposit = lower LVR = better rate
About Choices Floating with Offset
Westpac's Choices Floating with Offset lets you reduce mortgage interest by linking savings accounts. Money in your offset accounts reduces the balance on which interest is calculated, potentially saving you thousands over the life of the loan.
This product suits borrowers who maintain significant savings buffers — particularly self-employed individuals or those with lumpy income. The offset rate is the same as the standard floating rate, so the real benefit comes from having meaningful savings to offset. Westpac's cashback provides an additional incentive.
