| $588,000 (avg) | ~$3,450 | ~$1,725 | ~$865 |

2026 mortgage rates
As at mid-September 2026, carded rates at the big five are 4.59% – 4.69% for 1-year fixed and 6.14% – 6.34% floating (interest.co.nz). The longer terms are not listed here because we do not have a current source for them; check interest.co.nz rather than trust a figure from a blog.
The mid-year snapshot this section used to carry (floating ~5.7%, 1-year ~5.0–5.5%) was already a point out by September, which is how quickly this moves.
If you fixed at the 2023–24 highs, renewing still drops your repayment, but note that floating is now well ABOVE short fixed rates and the OCR is rising again, so floating is no longer the cheap option it was mid-cycle.
