Builder Insurance
Building is one of the highest-risk trades in New Zealand, and insurance costs reflect that. Builders need comprehensive coverage: public liability (protecting against injury and property damage on site), tools and equipment insurance, commercial vehicle cover for transport, and often statutory liability and professional indemnity if offering design services. The NZ building industry requires compliance with Building Information Memoranda (BIMs), council regulations, and WorkSafe requirements. A single incident on a building site—someone injured, property damaged, or tools stolen—can cost tens of thousands. Most councils require proof of public liability insurance before issuing building consents, making insurance not just smart business but a legal prerequisite for work. Premiums for builders typically range from NZ$150–400 per month depending on business size, claim history, and project types.

Building Consent and Insurance Requirements
Most NZ councils require proof of public liability insurance—typically minimum NZ$1 million—before issuing a building consent. Without valid insurance, you cannot legally obtain consent for most residential or commercial projects. This requirement applies to owner-builders as well as professional building firms. Always ensure your insurance is active before submitting consent applications.
Subcontractor Liability
When hiring subcontractors (plumbers, electricians, etc.), responsibility for their actions on your site can fall to you. Your public liability policy may not automatically cover their work. Best practice: ensure each subcontractor has their own valid public liability insurance and is named as insured on your certificate. Some policies allow you to extend cover to named subcontractors—discuss this with your insurer.
Contract Works Cover
Contract works insurance covers the building under construction against damage during the building process. It protects materials, temporary structures, and the building itself until handover. This is often a requirement of your client's mortgage lender or contract terms. It's separate from your general public liability and should be discussed with your broker.

Frequently Asked Questions
What insurance do I need to get a building consent?
Most councils require proof of public liability insurance—typically at least NZ$1 million—before issuing a building consent. Without valid insurance, you cannot proceed. Check your local council's requirements, but insurance is almost universally mandated for building work.
Do I need to cover subcontractors on my public liability?
Not automatically. Your policy covers your own work, but if you hire subcontractors, they should have their own insurance. You may want to extend your policy to cover named subcontractors, or ensure they're insured under their own policies. Always check your contract requirements.
What happens if someone is injured on my building site?
Report the incident to your insurer immediately and to WorkSafe if it's a serious injury (notifiable event). Your public liability insurance covers medical costs, legal defence, and settlements. Your insurer will investigate and manage the claim.
Is contract works insurance included in public liability?
No—contract works (cover for the building under construction) is separate from public liability. It's often a contract requirement. Discuss this with your broker to ensure you have adequate cover.
What's the average insurance cost for a building business?
Premiums typically range from NZ$150–400/month depending on business size, project types, location, and claims history. Larger builders with commercial projects pay more; small residential builders pay less. Get quotes from multiple providers to compare.
