Mortgage Types Compared — New Zealand 2026

Choosing the Right Mortgage in New Zealand

Selecting the right mortgage type is one of the most important financial decisions in the buying process. The wrong choice can cost you tens of thousands over the life of the loan. This guide explains every mortgage type available in New Zealand and helps you choose.

Types of Mortgages Available

New Zealand offers several rate structures. Fixed rate locks your rate for 6 months to 5 years — the 1-2 year fixed is the most popular choice. Floating rate moves with the OCR — typically the highest rate but fully flexible. Offset mortgage reduces interest by offsetting savings held in a linked account against the mortgage balance — floating rate but effectively lower cost. Revolving credit works like an overdraft secured against your property. Most Kiwi borrowers use a split strategy — dividing the mortgage across multiple fixed terms to manage renewal risk

Head-to-Head Comparison

The split strategy (multiple fixed terms) is uniquely New Zealand — it hedges renewal risk by ensuring portions come up for renewal at different times. 1-year fixed is cheapest but requires annual attention. 2-3 year fixed offers a balance of cost and stability. 5-year fixed provides maximum certainty at a premium. Floating is flexible but expensive. Offset suits those with significant savings they want to keep accessible

Which Type Is Right for You?

Your ideal mortgage type depends on your risk tolerance, financial stability, and market outlook.

Choose fixed rate if you value payment certainty, are on a tight budget with little room for payment increases, or believe rates will rise. Choose variable rate if you can absorb payment increases, want the lowest possible initial cost, or believe rates will stay stable or fall.

Consider your loan term carefully. Shorter terms mean higher monthly payments but dramatically lower total interest. Our mortgage guide provides a detailed analysis of how term length affects total cost.

Expert Tips for New Zealand

Split your mortgage across 2-3 different fixed terms (e.g. one-third on 1-year, one-third on 2-year, one-third on 3-year) to hedge renewal risk. Use KiwiSaver for your deposit — it is one of the most powerful first-home tools in the world. Always negotiate at refix time — banks have discretion to offer below-advertised rates

Refinancing Between Types

If you chose the wrong type, or if market conditions change, refinancing is always an option. Read our refinancing guide for a step-by-step walkthrough of switching products or lenders.
