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% | 5.79% |
| Deposit 5% – 9% | 5.79% |
| Deposit 10% – 14% | 5.79% |
| Deposit 15% – 19% | 5.79% |
| Deposit 20% – 24% | 4.99% |
| Deposit ≥ 25% | 4.99% |
Higher deposit = lower LVR = better rate
About Fixed 18 Month
TSB's 18-month fixed rate gives you a slightly longer horizon than a 1-year fix, providing more certainty without the full commitment of a 2-year term. It's a practical mid-point option for borrowers who like to time their refixing thoughtfully.
TSB's community banking ethos means a more personal service experience, and the bank has invested in digital channels to match larger competitors. The 18-month term is less commonly offered across the market, so TSB's pricing here can offer relative value.
