The 5-year fixed mortgage rate offers the maximum certainty of any standard fixed term in New Zealand — but comes at a meaningful rate premium. In the current environment (April 2026), a 5-year fix means accepting a rate considerably above the lowest available terms. Understanding when this trade-off is worthwhile is the key question.
5-Year Fixed Rates in New Zealand (April 2026)
| Bank | Indicative 5-year fixed rate |
|---|---|
| ANZ | ~5.89% |
| ASB | ~5.89% |
| BNZ | ~5.89% |
| Westpac | ~5.89% |
| Kiwibank | ~5.85% |
Indicative carded rates as at April 2026. Rates change frequently.
The Rate Premium vs Other Terms
| Term | Indicative rate (April 2026) | Premium vs 2-year |
|---|---|---|
| 2 years | ~5.45% | — |
| 3 years | ~5.69% | +0.24% |
| 5 years | ~5.89% | +0.44% |
| Floating | ~7.09% | +1.64% |
Annual cost of 5-year vs 2-year (on $600,000 mortgage): 0.44% × $600,000 = $2,640/year — or $220/month extra for 5 years of rate certainty.
Over the full 5-year period, this premium is approximately $13,200 in additional interest vs having fixed at 2-year rates for the same period (holding rates constant — which they won’t be).
This premium is only worthwhile if you genuinely need 5 years of certainty, or if you believe the 2-year rate in 2 years will be significantly higher than today’s 5-year rate (i.e., rates are about to rise sharply).
Who Should Consider 5-Year Fixed?
Good fit for 5-year fixed:
- Businesses and investors with fixed income needs — if your rental income budget or business plan requires a known financing cost for 5 years, the premium buys planning certainty
- Single-income households at borrowing capacity — if you’re borrowing at or near your limit and a rate increase at rollover would cause financial hardship, 5 years of certainty could be worth the premium
- Borrowers who hate managing their mortgage — some people genuinely don’t want to think about their mortgage for 5 years; if that’s you, the premium is the cost of peace of mind
- Rate rise scenario — if you believe interest rates are about to rise significantly and the OCR is heading higher, locking at current rates for 5 years could save money. (Note: As at April 2026, the consensus expectation is rates will be relatively stable or slightly lower — not materially higher.)
Not suitable for 5-year fixed:
- Borrowers who may sell in the next 5 years (break fees can be very large)
- Borrowers expecting rate falls (the 2-year rate will likely be lower than today’s 5-year if rates drop)
- First home buyers who may upsize within 5 years
Monthly Repayments at 5-Year Rate
| Loan amount | Monthly repayment at 5.89% (30-year term) |
|---|---|
| $400,000 | ~$2,369 |
| $500,000 | ~$2,961 |
| $600,000 | ~$3,553 |
| $750,000 | ~$4,441 |
| $900,000 | ~$5,330 |
5-Year Fixed: Break Fee Warning
The break fee risk on a 5-year fixed mortgage is the largest of any standard term. In year 1 of a 5-year fix, breaking early with significant remaining term and a meaningful rate movement could result in fees of $20,000–$50,000+ on a large mortgage.
Example: $700,000 mortgage, fixed at 5.89% for 5 years. You break in month 18. Bank’s current 3.5-year rate is now 4.5%. Simplified break fee: ($700,000 × (5.89% − 4.5%) × (3.5/12)) ≈ approximately $28,000.
This is a simplified illustration — actual calculations are more complex. The key point: never fix for 5 years if there is any realistic chance you will sell or need to break the mortgage in the next 3–4 years.

Historical Context
When 5-year fixed was popular: During periods of very low rates (e.g., 2020–2021 when rates were 2.5%–3.5%), the 5-year rate represented exceptional value — locking in cheap money for a long period. Many borrowers who fixed at 3% for 5 years in 2020 are still enjoying those rates in 2025.
Current context (April 2026): At ~5.89%, the 5-year rate is materially above the 2-year rate. The value proposition is primarily about certainty, not rate bargaining — unlike the 2020–2021 scenario.
Alternatives to 5-Year Fixed
If you want more certainty than 2 or 3-year fixed but don’t want the full 5-year premium and break risk:
- 3 + 2 split: Fix half for 3 years, half for 2 years — staggered refixing reduces rollover risk without locking the full premium
- Revolving credit: For borrowers who can build significant cash reserves, a revolving credit facility gives flexibility without a break fee
- Longer amortisation review — changing your repayment term rather than your rate doesn’t incur a break fee
