The 3-year fixed mortgage rate sits above the 1 and 2-year terms in New Zealand’s current rate environment, but offers significantly more certainty — you know exactly what your rate will be for 3 years. Understanding when that certainty is worth the premium is key to the decision.
3-Year Fixed Rates in New Zealand (April 2026)
| Bank | Indicative 3-year fixed rate |
|---|---|
| ANZ | ~5.69% |
| ASB | ~5.69% |
| BNZ | ~5.69% |
| Westpac | ~5.69% |
| Kiwibank | ~5.65% |
Indicative carded rates as at April 2026. Actual rates change frequently.
At April 2026, the 3-year rate (~5.69%) is higher than the 2-year rate (~5.45%). This term premium reflects the market’s view that rates will stabilise — you’re paying a premium for 3 years of certainty vs 2 years.
Rate Comparison Across Terms
| Term | Indicative rate (April 2026) | Difference from 2-year |
|---|---|---|
| 1 year | ~5.55% | +0.10% |
| 2 years | ~5.45% | — (lowest) |
| 3 years | ~5.69% | +0.24% |
| 5 years | ~5.89% | +0.44% |
| Floating | ~7.09% | +1.64% |
The cost of certainty: fixing for 3 years instead of 2 years currently costs approximately 0.24% extra per year on your mortgage.
Annual cost of 3-year vs 2-year (on $600,000 mortgage): 0.24% × $600,000 = $1,440/year — or $120/month extra for 3 years of rate certainty vs 2 years.
Who Should Choose 3-Year Fixed?
Good fit for 3-year fixed:
- Certainty-focused borrowers — you want to know exactly what your mortgage will cost for 3 years and are willing to pay a moderate premium for that
- Borrowers on a tight budget — if your repayment budget is stretched, a rate surprise at rollover could cause real stress; 3 years gives you time to build buffer
- Families expecting one income to drop — parental leave, one partner stopping work to care for children; locking a known rate for 3 years removes one financial uncertainty
- Borrowers who believe rates won’t fall further — if the OCR easing cycle is largely complete, the 3-year rate locks you at a rate that won’t be dramatically lower in 1–2 years anyway
- Property investors — certainty in rental yield calculations
Less suitable for 3-year fixed:
- Borrowers who believe rates will fall significantly in the next 12–18 months (1 or 2-year better)
- Borrowers planning to sell within 3 years (break fees can be substantial)
- Those with high revolving income who can tolerate rate variability
Monthly Repayment at 3-Year Rate
| Loan amount | Monthly repayment at 5.69% (30-year term) |
|---|---|
| $400,000 | ~$2,321 |
| $500,000 | ~$2,901 |
| $600,000 | ~$3,481 |
| $750,000 | ~$4,351 |
| $900,000 | ~$5,221 |
Comparison: On a $600,000 mortgage, 3-year fixed ($3,481/month) vs 2-year fixed ($3,383/month) = $98/month difference.
3-Year Fixed: Break Fees
Breaking a 3-year fixed term early can be expensive, particularly in the first 1–2 years:
- Maximum exposure: A break in month 1 of a 3-year fixed on a $600,000 loan, if market rates have fallen 1% since you fixed, could cost approximately $17,000
- Typical mid-term break: $2,000–$10,000 depending on remaining term, loan size, and rate movement
- Late-term break: Much lower, as remaining time diminishes
Warning: If you’re unsure whether you’ll stay in the property for 3 years, a 3-year fixed is riskier than a 1 or 2-year. Always assess your probability of early sale before choosing a longer term.

Rolling Over from 3-Year Fixed
When your 3-year fixed expires, you have the same refixing options as any other term. Because rates in New Zealand’s current environment may be different in 3 years (depending on OCR direction), your best move at that point depends on the market at the time.
Tip: When you fix for 3 years, calendar a review point at 2 years 6 months (6 months before expiry). This gives you:
- Time to assess rate trends
- Time to negotiate without pressure
- Time to arrange an alternative lender if switching
3-Year Fixed as Part of a Split Strategy
A common approach: split your mortgage between a 2-year and 3-year term.
Example ($700,000 mortgage):
- $350,000 at 2-year fixed (5.45%) — refixes in 2 years
- $350,000 at 3-year fixed (5.69%) — refixes in 3 years
This staggers your exposure so you’re never refixing your entire mortgage at once — reducing risk. See Split Mortgage NZ.
