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% | 6.49% |
| Deposit ≥ 10% | 6.49% |
| Deposit ≥ 15% | 6.49% |
| Deposit ≥ 20% | 6.49% |
| Deposit ≥ 25% | 5.69% |
Higher deposit = lower LVR = better rate
About Fixed 5 Year
TSB's 5-year fixed mortgage provides the longest period of rate certainty available, locking your repayments for five full years. It suits the most stability-focused borrowers who want absolute certainty in their budgeting.
TSB's 5-year rate is typically competitive with or below the Big Four banks on this term. As with all long-term fixes, the risk is overpaying if rates fall — but the reward is complete peace of mind in a rising-rate environment.
