The Split Mortgage Strategy

Many borrowers choose a split mortgage - part fixed and part floating. This gives you the best of both worlds.

Example: $600,000 Mortgage

Fixed 2-Year

$400,000

67% of loan

Floating

$200,000

33% of loan

Benefit

Extra repayments + certainty

Pro Tip: Laddering Strategy

Split your fixed portions across different terms (e.g., 1-year, 2-year, 3-year). This means you're always reviewing part of your mortgage annually, reducing the risk of being locked into unfavorable rates.

Fixed vs Floating FAQs

Should I fix my mortgage rate in NZ?

Fix if you want certainty and rates are likely to rise. In 2026, with rates potentially falling, shorter fixed terms (1-2 years) or a split mortgage (part fixed, part floating) may be optimal.

What is the difference between fixed and floating rates?

Fixed rates stay the same for a set period (1-5 years), giving payment certainty. Floating rates move with market conditions, currently higher but offering flexibility and no break fees.

Can I switch from fixed to floating?

Yes, but you'll pay a break fee if you exit a fixed term early. Break fees can be substantial depending on how much rates have moved since you fixed.

What is a split mortgage?

A split mortgage has part of your loan on fixed rates and part on floating. This gives you certainty on some payments while maintaining flexibility on others.

How long should I fix my mortgage for?

Consider fixing for 1-2 years if rates are expected to fall, 3-5 years if they may rise. Most borrowers choose 2-year fixed as a balance of rate and flexibility.
