How to Use the NZ Mortgage Market Monitor

This page tracks rate movements and competitive positioning across the major banks that most New Zealand borrowers compare when they refix. Use it to see what changed recently, who's been most competitive, and how wide the pricing gaps are.

Why market context matters

If one bank is clearly leading the 1-year or 2-year term, that tells you where price pressure sits right now. If several banks are tied, it usually means pricing is clustered and the decision comes down more to your own break-even than to chasing one standout offer.

What to do next

Once you find the terms you care about, run them through the MyRefix calculator to see how the repayment and break-even trade-offs look on your own mortgage. If you want a raw rate table first, head to Compare Rates.
