You can often buy with a 10% deposit, or even 5% if you qualify for the First Home Loan. The [first home buyer guide](https://buyingahouse.co.nz/buying/first-home-grant) explains how lower deposits work and what they cost.

Repayments are based on a 30-year term at 4.95% a year, which was the Reserve Bank's average advertised 1-year special rate at the end of October 2026. Special rates often need a 20% deposit, and banks may charge a low equity margin or fee if your deposit is smaller, so you might pay more.

## Choosing a mortgage broker

The FMA suggests talking to more than one adviser and asking each of them:

- what licence they have, or whose licence they work under
- which lenders and products they can advise on
- how they are paid, and whether you will pay any fees
- how you can complain, and which dispute resolution scheme they belong to.

You can check a broker's licence on the Financial Service Providers Register. Ask for any fees in writing.
