Public Liability Insurance — NZ Guide
Public liability insurance is the foundation of tradie insurance in New Zealand. It protects you and your business against claims for third-party property damage or bodily injury caused by your work activities. Whether you're working on a residential site or a commercial project, public liability cover is essential—most councils, contracts, and commercial clients require proof of valid cover before work begins. Coverage typically ranges from NZ$1 million to NZ$5 million, with higher limits recommended for larger projects and commercial work. Premiums start from around NZ$30 per month for sole traders but increase based on your trade, business size, and claims history.
What's Covered
Coverage Overview
Public liability insurance covers claims made against you by third parties—your clients, their property, or members of the public—for accidental injury or property damage caused by your work. This includes damage to buildings, vehicles, personal property, and injuries sustained by people on or near your work site. The insurance covers legal costs, court awards, and settlement payments up to your policy limit.
Why Every Tradie Needs It
In New Zealand, public liability insurance is practically mandatory for professional tradies. Building consent authorities, local councils, and commercial clients almost universally require proof of valid cover before awarding contracts. Without it, you could face significant financial exposure—a single major incident could bankrupt an uninsured business. Additionally, many insurance contracts and lease agreements include liability requirements.
Coverage Limits Explained
Public liability policies typically come with aggregate limits of NZ$1 million, NZ$2 million, or NZ$5 million. Small sole traders may start with NZ$1m, but most residential builders and tradespeople use NZ$2m. Commercial projects and larger businesses should consider NZ$5m coverage. Higher limits provide greater protection and are often required by larger clients and councils.

Frequently Asked Questions
Is public liability insurance a legal requirement in New Zealand?
Public liability is not mandated by law, but it is practically required. Most contracts, councils, building consent authorities, and commercial clients require proof of valid cover before awarding work. Without it, you cannot realistically operate as a professional tradie in New Zealand.
What's the difference between NZ$1 million and NZ$5 million cover?
The difference is the maximum amount the insurance company will pay for a single incident. Larger limits protect against major incidents—construction sites and commercial work typically require NZ$5m or higher. For small residential jobs, NZ$1m–2m may suffice, but check your specific contracts.
Does public liability cover subcontractors?
Usually not automatically. Your policy covers your work, but if you hire subcontractors, they should have their own insurance. Some policies allow you to extend cover to named subcontractors—always check your policy wording and discuss with your insurer.
What am I not covered for under public liability?
Public liability typically excludes intentional damage, damage from poor workmanship (unless contractually required), liability arising from deliberate breaches of health and safety law, and certain specific exclusions listed in your policy. Professional indemnity insurance (not public liability) covers errors in design or advice.
How quickly can I claim under public liability?
You should report any incident to your insurer as soon as possible—ideally within 30 days. The sooner you report, the better; insurers can investigate while evidence is fresh. Claims can take weeks to months to settle depending on complexity and dispute.
