What's the big deal about home insurance then?

There are some important things you need to know about


This site is brought to you by IAG New Zealand Limited (IAG), the country's largest provider of general insurance, with the aim of helping New Zealanders to understand key aspects of home insurance underwritten by IAG and what you may need to know or do when renewing or taking out a home policy with us.

IAG is the owner of the AMI, State, NZI, Lumley and Lantern Insurance brands and underwriter for most of the home insurance offered by ASB, BNZ, Westpac and The Co-operative Bank, as well as the underwriter for many home policies offered by Aon, Crombie Lockwood and many other New Zealand insurance brokers.

If your home isn't insured with IAG, this site will still help you understand some aspects of the home insurance offered by other New Zealand insurers and you may still use the calculator to estimate the likely cost of rebuilding your home.

For convenience, all references to 'IAG' on this website mean IAG business divisions operating in New Zealand.

If you own a home or are thinking of buying one, it's important to understand how home insurance works for many of us.

What you'll find here

This site provides resources to help you understand what you need to know and what you need to do and direct you to places where you can get support. It also provides an easy-to-use online calculator that can help you estimate the potential cost of rebuilding your home, so you can be better placed to make decisions about the level of cover that you think is right for your home.
