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% | 7.20% |
| Deposit ≥ 10% | 6.95% |
| Deposit ≥ 15% | 6.20% |
| Deposit ≥ 20% | 5.70% |
Higher deposit = lower LVR = better rate
About Fixed 18 Month
Westpac's standard 18-month fixed rate provides a mid-length fix for borrowers on the standard pricing tier. It offers slightly more certainty than a 1-year fix and bridges the gap to the 2-year term.
The rate is higher than the special 18-month equivalent, but Westpac's cashback and banking services still provide good overall value. As your equity grows, you may become eligible for special pricing at your next refix.
