Public Liability Insurance

What Is Public Liability Insurance for Sole Traders?

Public liability insurance protects you when a third party — a client, member of the public, or bystander — suffers bodily injury or property damage because of your business activities. As a sole trader, you have no corporate shield between you and a claim: if you're sued, your personal assets are at risk. Public liability insurance steps in to cover legal costs and compensation, so a single accident doesn't wipe out everything you've built.

Why Sole Traders Need Public Liability Cover

Unlike employees, sole traders carry full personal liability for their work. If a tradie accidentally damages a client's new kitchen, or a cleaner knocks over an expensive sculpture, the client can sue directly. Even a claim you successfully defend can cost tens of thousands in legal fees — money most small operators simply don't have.

Public liability is also increasingly a commercial requirement. Local councils, large contractors, and property managers regularly ask for proof of $1 million to $2 million in cover before they'll award contracts or let you on site. Without it, you lose work.

What Does Public Liability Cover?

Third-party bodily injury: A client trips over your gear and breaks their wrist. Your insurer covers their medical costs, lost earnings, and any compensation awarded.

Third-party property damage: You're waterblasting a deck and the pressure strips paint off an adjacent fence. Your policy covers repair or replacement.

Products liability: If you supply goods as part of your work — a plumber fitting a hot water cylinder, a food truck selling meals — and those products cause harm, this extension covers the resulting claims.

Legal defence costs: Even spurious claims must be defended in court. Your insurer pays solicitor and barrister fees, expert witnesses, and court costs regardless of the outcome.

How Much Cover Do You Need?

Most sole traders in NZ choose between $1 million, $2 million, and $5 million of cover. The right level depends on your work:

- $1 million: Suitable for low-risk sole traders such as consultants who meet clients in offices, market stall operators, and low-hazard service providers.
- $2 million: The standard for most tradies, cleaners, personal trainers, and anyone working in or around residential or commercial properties.
- $5 million: Required when working for large commercial clients, government contracts, or in high-risk environments such as construction sites or public events.

What Is the Cost of Public Liability Insurance?

Premium pricing varies significantly based on your trade, revenue, number of years in business, and claims history. As a rough guide for NZ sole traders:

- Consultants and office-based professionals: $300–$500 per year
- Cleaners, gardeners, low-risk tradies: $400–$600 per year
- Builders, electricians, plumbers: $600–$1,200 per year
- High-risk or specialist trades: $1,000–$2,000+ per year

These are indicative ranges. An adviser can shop across multiple NZ insurers — Vero, NZI, QBE, Delta Insurance, and others — to find the most competitive rate for your specific situation.

NZ-Specific Considerations

New Zealand's ACC scheme covers personal injury from accidents, but it doesn't cover the legal costs or compensation if you injure someone else. If you're liable for a third party's injury, ACC may cover their treatment but you're still exposed to a civil claim for their lost income, pain and suffering, and other damages. Public liability insurance covers that exposure.

Health and Safety at Work Act 2015 (HSWA) also places duties on businesses that could be a client or PCBU in your context. While HSWA enforcement typically results in WorkSafe NZ fines (not civil claims), the culture of safety accountability it creates makes public liability more important than ever.

Getting Covered

The process is straightforward. A licensed NZ insurance adviser will ask about your trade, annual turnover, the nature of your work, and any prior claims. They'll then compare quotes from multiple insurers and present the best options. Cover can often be bound within 24 hours.
