Should I be a guarantor for someone's loan?

Common question · Banking & Finance Law · New Zealand · 23 October 2026

General information from Lawmateanz

Being a guarantor means you're promising to repay a loan if the borrower doesn't. In New Zealand, if they default, the lender can come after you for the full amount, including interest and costs, and may be able to take security over your assets.

Before signing, read the guarantee, understand the loan amount, and consider whether you could afford to pay it.

Many lenders require you to get independent legal advice before signing, which is a good idea anyway.

Ending a guarantee later can be difficult, so ask whether it can be limited in amount or time.
