But I don't know anything about building houses

Don't worry, you only need to know about your own home

Estimate your potential rebuilding cost

Ready to estimate what it could cost to rebuild your home? Depending on how well you know your home, the easy-to-use calculator on this site may take just a few minutes to complete or a little longer if you take more time over some of the questions.

How reliable is the calculator?

The calculator is intended to provide a free, easy-to-use way of estimating the potential cost of rebuilding a home. While reasonable care is taken by the provider, Cordell, to maintain the data it draws on, the estimated rebuilding cost it produces is intended as a guide only. It does not substitute an insurance valuation provided by a registered valuer or any other kind of home valuation provided by a building expert.

Note that the calculator is not suitable for extremely large homes (in excess of 700 square metres) or high value homes where the likely cost of rebuilding would exceed $2 million.

Using the right information

The accuracy of the information you enter in the calculator has a bearing on its estimate of the likely cost of rebuilding your home. It's important to enter the best information you can so the estimate is as representative of your home as it can be.

How the calculator works

This calculator draws on data from around New  Zealand about many aspects of home construction and reconstruction. The information is updated regularly.

The amount produced by the calculator includes anticipated construction costs and allowances for professional fees, demolition, removal of debris and GST - things people often don't consider when thinking about the cost of rebuilding their home.

Does it allow for Recreational Features and retaining walls?

The calculator identifies the potential costs associated with rebuilding retaining walls and Recreational Features like swimming pools separately. If your home has any of these features, the calculator will help you identify whether you need to purchase cover or additional cover for them under your policy. However, depending on the nature and extent of the particular features in your home, you may choose to check the estimated rebuilding cost the calculator produces for these features to decide if it is sufficient.

Does it allow for Special Features?

The calculator does not estimate the cost of rebuilding Special Features (as defined in IAG home policies). If you require cover for any of these items you'll need to talk to your insurance provider and purchase additional cover.

What doesn't the calculator allow for?

The amount produced by the calculator does not include fixed floor coverings such as carpets. It also makes no allowance for changes in building costs over the policy period, or the period of repair or rebuilding that would take place following damage to your home. If you wish to include an allowance for these items in your Sum Insured you will need to add them to the amount produced by the calculator.

What happens to your information

The information you enter into the calculator is not stored or passed on to your insurer. It's used solely for the purposes of estimating the likely cost of rebuilding your home.

When you've completed your calculation you can print out a PDF of the result or save a copy of it on your computer. That way you'll have a record of the information your estimate is based on.
