Should You Fix or Float a Mortgage in NZ?

If your home loan is coming up for renewal, you are stepping into a changing and uncertain interest rate environment. In September 2026, the Reserve Bank of New Zealand (RBNZ) increased the Official Cash Rate (OCR) to 2.75%. The RBNZ expects inflation to remain elevated through the rest of 2026 before returning towards its 2% target during 2027.

For Kiwi homeowners and property investors alike, deciding how to structure your loan right now is critical. Getting your mortgage structure right can save you thousands in interest and protect your cash flow against the rising cost of living.

Should I fix or float my mortgage right now?

There is no one-size-fits-all answer. Currently, floating rates are generally higher than the shorter fixed rates available from major lenders, making fixing an option worth considering for borrowers who want greater repayment certainty. For property investors in particular, fixing ensures your rental yield remains predictable, protecting your cash flow against the rising costs of rates and insurance.

However, the smartest strategy is often a hybrid approach: splitting your mortgage so a large chunk is fixed, while a smaller, manageable portion remains floating.

Is a floating rate better than fixed in a shifting market?

When people ask, “is a floating rate better than fixed,” they are usually thinking about flexibility, not just the headline rate.

The major advantage of a floating mortgage is absolute freedom. If you have extra cash – perhaps from a work bonus, an inheritance, or selling off an investment property, a floating rate allows you to aggressively pay down your debt immediately without being hit by early repayment penalty fees.

If your income fluctuates or you plan to sell your house in the near future, leaving a portion of your mortgage floating gives you the tactical flexibility you need.

Another consideration could be a revolving credit/offset facility. It would be a good idea to talk to a mortgage adviser to compare those options and find out which path is right for you.

Should I fix my mortgage for 1 or 2 years in NZ?

If you decide to fix, the next major hurdle is choosing the term. In the current 2026 landscape, shorter fixed terms are proving incredibly popular. With the RBNZ forecasting that inflation might spike slightly in the short term before settling back down to the 2% target by mid-2027, many borrowers are avoiding long-term fixed rates (like the 3-year or 5-year options).

• The 1-Year Fix: This is ideal if you want a “wait-and-see” approach. It gives you immediate relief from higher floating rates but allows you to renegotiate in 12 months, just in case rates start dropping again.
• The 2-Year Fix: This provides a bit more stability and is often priced very competitively by the major banks. It allows you to ride out the current economic uncertainty without locking yourself in for half a decade.

For property investors, a mix of 1-year and 2-year terms across different properties can prevent all your debt from renewing at the exact same time, effectively spreading your risk.
