What is builders’ insurance?
Business insurance helps builders protect their growing businesses. Depending on the types cover you choose, it could help manage claims costs like client property damage, a third-party injury, design defects, and stolen or damaged tools.
Situations like these (and many others) could create unplanned expenses for your business. If paying legal costs out of pocket for investigating, defending, and settling claims would rock the foundations of your business, it may be time to consider business insurance to protect your business and your reputation.


Why might builders need insurance?
Business insurance isn’t mandatory in NZ for most businesses, but as part of the New Zealand New Building Act builders are required to declare details of the insurance they hold to their customers.
You may be required to have a policy to do things like:
Enter a jobsite.
Pay legal costs if you face a claim.
Work as a contractor or subcontractor
Lease a worksite

Unsure how much to choose? Think about:
Underinsurance
We know it’s tempting to select a lower level of cover to reduce premiums, but this can leave businesses shocked and insufficiently covered when making a claim.
Ways underinsurance catches business owners out:
Inflation
With inflation, the cost of living and doing business increases. Remember to cover you, your tools and assets for the rising costs of replacing or covering them, not what you paid for them – you may be surprised at the difference.
Not covering the full cost of your risks
If you select cover levels for less than the value you may be found liable – left out of pocket when it comes to claims time. It’s important to review your risks and determine how much you will need to cover any claim that may come your way.

Builders claims examples
Could this happen to your business?
Here are some examples of real BizCover customers who had to make a claim.
What went wrong
A builder was grinding steel near their clients’ windows, they covered the windows with fire-rated building wrap, but the wind lifted the wrap resulting in sparks damaging the glass.
Outcome
The builder made a Public Liability claim with their insurer, who assessed the builder had made reasonable steps to avoid the damage, and paid $5,300 to cover the costs of repairing the windows.
What went wrong
A builder was repairing a deck, they poured concrete to secure posts, but the weight of the concrete crushed part of an underground drainage pipe which was not visible. The drainage system later overflowed with greywater.
Outcome
The builder made a Public Liability claim with their insurer who agreed to pay $560 to cover the cost of hiring a plumber to repair the damage.
These builders had both covered their third-party property damage risk with Public Liability insurance, which covered them financially when a situation occurred where they had to make a claim.
The provision of the claims examples are for illustrative purposes only and should not be seen as an indication as to how any potential claim will be assessed or accepted. Coverage for claims on the policy will be determined by the insurer, not BizCover.
