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% | 6.35% |
| Deposit ≥ 10% | 6.15% |
| Deposit ≥ 15% | 5.60% |
| Deposit ≥ 20% | 5.15% |
| Deposit ≥ 25% | 4.85% |
Higher deposit = lower LVR = better rate
About ASB Fixed 18 Month
The ASB 18-month fixed term sits between the standard 1-year and 2-year options, offering a useful middle ground. It's a good choice when you want slightly more certainty than a 1-year fix but aren't ready to commit for a full two years.
This term is less widely promoted across the market, so ASB's offering can stand out during periods when the 18-month rate is priced attractively relative to 1-year and 2-year alternatives. It's particularly popular with those who time their refixing cycles around personal milestones.
