Fixed vs Floating Mortgage Rates in NZ: Which Is Right for You in 2026?

Fixed vs floating mortgage rates in NZ for 2026 - current rates, how each works, and which suits different borrower situations.

Tom - Proply Editorial Team 9 May 2026

Quick Answer: As of mid-2026, the lowest fixed rates sit around 4.49% for 6 months and 5.19-5.39% for 2-4 years, with floating rates typically higher but more flexible - fixed suits borrowers who want payment certainty, while floating suits those expecting to sell, refinance, or make lump-sum repayments soon.

Where Rates Sit Right Now

The Official Cash Rate is currently 2.25%, with the Reserve Bank expected to lift it toward 3% over the next six months. Against that backdrop, the lowest 6-month fixed rate available is around 4.49% (ASB and Kiwibank), the lowest 1-year rate is 4.65% (ANZ and ASB), 2-year rates are around 5.19% (Westpac), and 3-4 year rates sit between 5.29% and 5.39%.

Longer-term fixed rates are edging up while shorter-term rates hold near recent lows - a shift that's made fixing at least part of your loan for a shorter term more appealing to many borrowers this year.

How to Choose Between Them

Fixed rates lock in your repayment amount for a set term, giving certainty but limited flexibility - break fees can apply if you repay early or refinance mid-term. Floating rates move with the market and usually sit a little higher, but let you make extra repayments or repay the loan in full without penalty at any time.

  • Choose fixed if budget certainty matters most, or you expect rates to keep rising
  • Choose floating if you plan to sell, make lump-sum repayments, or want maximum flexibility
  • Consider splitting your mortgage between fixed and floating portions for a mix of certainty and flexibility
