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 5% – 9% | 6.05% |
| Deposit 10% – 14% | 5.60% |
| Deposit 15% – 19% | 5.20% |
| Deposit 20% – 24% | 4.85% |
| Deposit ≥ 25% | 4.85% |
Higher deposit = lower LVR = better rate
About Fixed 18 Month
BNZ's 18-month fixed rate offers slightly more certainty than a 1-year term, paired with BNZ's cashback incentive. It's a solid choice when you want a bit more breathing room before your next refix decision but don't want to commit for two full years.
BNZ often prices the 18-month term competitively relative to other banks. The combination of a mid-length fix and upfront cashback makes this attractive for first-home buyers juggling settlement costs alongside their mortgage.
