Public Liability Insurance NZ: What It Covers, Who Needs It, and What It Costs
Public liability insurance covers a New Zealand business when it is legally liable for injuring a member of the public or damaging property belonging to someone else, paying legal defence costs and any compensation awarded. It is not required by law. Cover levels run from $1,000,000 for low-risk sole traders to $5,000,000, which is increasingly the standard minimum for construction subcontractors, and $10,000,000 or more on some government contracts.
In short
- No New Zealand law requires public liability insurance, but clients, landlords and main contractors routinely ask for proof of cover before they will engage you.
- Cover levels run from $1,000,000 for low-risk sole traders and $2,000,000 for most small businesses to $5,000,000 for tradies, builders and event organisers.
- Public liability excludes professional advice errors, which fall to professional indemnity, and injuries to your own employees, which sit with ACC.
Public liability insurance is the third-party cover a New Zealand business holds against claims for injury to the public and damage to property it does not own, from a customer tripping on a loose cable to a marquee collapsing across $15,000 of AV equipment. There is no statutory requirement to hold it, yet main contractors, landlords and clients routinely want a current certificate before work starts, and in construction $5,000,000 is increasingly the standard minimum.
Public liability insurance exists to cover the financial consequences when your business activities cause injury to a third party or damage to their property. It is one of the most common forms of business insurance in New Zealand, and for many trades and industries, it is effectively a requirement to operate.
This guide covers what public liability insurance actually protects, which businesses need it, what drives the cost, how to choose the right level of cover, and how it differs from other types of liability insurance.
What Does Public Liability Insurance Cover?
Public liability insurance covers legal defence costs, compensation payments, accidental damage to third-party property, bodily injury to people who are not your employees, products liability in some policies, and tenant's liability for premises you rent, when your New Zealand business is legally liable for injury or damage caused during its activities.
- Legal defence costs. If a claim is made against you, the policy pays for legal representation, even if the claim is ultimately unsuccessful.
- Compensation payments. If you are found liable, the policy pays the damages awarded to the claimant.
- Property damage. Accidental damage to a client's or member of the public's property caused by your business operations.
- Bodily injury. Physical injury to a person who is not your employee, caused by your business activities.
- Products liability. Some public liability policies include cover for injury or damage caused by products you sell, supply, or manufacture.
- Tenant's liability. Damage to premises you rent or lease for business purposes.
The key word throughout is "third party." Public liability insurance protects you against claims from people outside your business: customers, clients, members of the public, and visitors to your premises.
What Public Liability Insurance Does NOT Cover
Public liability insurance in New Zealand excludes professional advice errors, which fall to professional indemnity, injuries to your own employees, which sit with ACC, statutory liability and employers liability, intentional acts, damage to your own property, motor vehicle incidents, and cyber incidents such as data breaches, which need a dedicated cyber policy.
Professional advice errors
If a client suffers financial loss because of incorrect advice, a design error, or a professional oversight, that is not a public liability claim. That is a professional indemnity claim. An architect whose building design is structurally flawed, an accountant who provides incorrect tax advice, or a consultant whose recommendations lead to financial loss would need professional indemnity insurance, not public liability.
Employee injuries
New Zealand's ACC scheme covers personal injuries sustained by employees at work. Beyond ACC, employers may need statutory liability insurance (which covers fines and penalties under the Health and Safety at Work Act 2015) and employers liability insurance (which covers claims that fall outside ACC). Public liability insurance specifically excludes injuries to your own employees.
Intentional acts
Deliberate damage or intentional wrongdoing is excluded from all liability policies. The act must be accidental or negligent for a claim to be valid.
Damage to your own property
Public liability covers damage to other people's property, not your own. Your own tools, equipment, and premises would be covered under material damage or contents insurance.
Motor vehicle incidents
Damage or injury caused by the use of motor vehicles is generally excluded from public liability policies and handled by motor vehicle insurance and ACC.
Cyber incidents
Data breaches, cyber attacks, and related liabilities are excluded. These require a dedicated cyber insurance policy.
ACC and Public Liability: Understanding the Difference
ACC and public liability insurance serve different purposes in New Zealand. ACC is a no-fault scheme covering personal injury regardless of fault, funded by the levies every business pays, while public liability covers property damage, legal defence costs and exemplary damages that ACC does not touch. A plumber who floods a kitchen has no ACC cover for that loss.
What ACC covers: ACC covers personal injury to any person in New Zealand, regardless of fault. If a customer is injured on your premises, ACC will cover their medical treatment, rehabilitation, and a portion of lost earnings. This is funded by the levies every business pays.
What ACC does not cover:
- Property damage. If your business damages a client's property, ACC has nothing to do with it. A plumber who floods a kitchen, an electrician who causes a fire, or a cleaner who stains an expensive carpet has no ACC cover for those costs. That is a public liability claim.
- Claims from overseas visitors. While ACC covers visitors to New Zealand in many circumstances, claims from people injured by your business operations overseas, or claims made under foreign jurisdictions, are not covered by ACC.
- Pain and suffering. Under New Zealand law, individuals generally cannot sue for compensatory damages for personal injury (this is the "ACC bar"). However, there are exceptions, and the legal costs of defending such claims can still be substantial.
- Exemplary damages. Courts can award exemplary damages for egregious conduct, and ACC does not cover these.
The bottom line: ACC levies and public liability insurance serve completely different purposes. ACC is a no-fault personal injury scheme. Public liability insurance covers property damage claims, legal defence costs, and the gaps that ACC does not fill.
Which Businesses Need Public Liability Insurance?
Almost any New Zealand business that interacts with the public, visits client premises or provides physical services should carry public liability cover. Tradies, construction, hospitality, retail, event organisers and fitness operators face the highest exposure, and many main contractors will not allow subcontractors on site without a current public liability certificate.
High-risk industries (public liability is essential)
- Tradies and construction. Builders, electricians, plumbers, painters, roofers, landscapers. Working on client property creates constant exposure to property damage and injury claims. Many main contractors will not allow subcontractors on site without a current public liability certificate.
- Hospitality and food service. Restaurants, cafes, caterers, bars. Slip-and-fall claims, food-related illness, and damage to event venues are common.
- Retail. Any business with a physical shopfront where customers enter. Trip hazards, falling displays, and product-related injuries are standard risks.
- Event organisers. Concerts, markets, festivals, corporate events. Large gatherings create significant liability exposure.
- Fitness and recreation. Gyms, personal trainers, yoga instructors, adventure tourism operators. Physical activity increases the likelihood of injury claims.
Moderate-risk industries (strongly recommended)
- Cleaners and maintenance. Working inside client homes and businesses. Risk of property damage (chemical stains, broken items) and slip-and-fall claims.
- Photographers and videographers. Working at events and on client premises with equipment that could cause injury or damage.
- Hairdressers and beauty therapists. Chemical reactions, burns, and allergic responses can trigger claims.
- Tutors and coaches. Anyone working with children or in client homes.
Lower-risk but still advisable
- Home-based businesses. If clients visit your home office, or you visit client premises, you still have exposure.
- Market stall operators. Even a weekend market stall creates liability. A display falls on a customer, a product causes an allergic reaction, or a tent blows over in the wind.
If you are unsure whether your business needs public liability cover, ask yourself: could my business activities injure someone or damage their property? If the answer is yes, even occasionally, you should have cover in place.
How Much Does Public Liability Insurance Cost in NZ?
Public liability insurance is one of the more affordable business insurance products available, and what you pay is driven by four things: your industry, your annual turnover, the cover level you select, and your claims history. Industry is the dominant factor, which is why a graphic designer and a builder holding identical cover pay very different amounts. The table below ranks common business types against each other so you can see roughly where you will sit before you request a quote.
| Business Type | Annual Revenue | Cover Level | Relative premium level |
|---|---|---|---|
| Sole trader (low risk, e.g., graphic designer) | Under $100,000 | $1,000,000 | Lowest |
| Cleaner or home services | $50,000 to $150,000 | $1,000,000 | Low |
| Personal trainer or fitness instructor | $50,000 to $150,000 | $2,000,000 | Low to moderate |
| Electrician or plumber | $100,000 to $500,000 | $2,000,000 | Moderate |
| Builder or construction subcontractor | $200,000 to $1,000,000 | $5,000,000 | High |
| Retailer with physical premises | $200,000 to $500,000 | $2,000,000 | Moderate |
| Event organiser | Varies | $5,000,000 | Highest of this group |
These rankings are relative rather than absolute, and your own price will vary by insurer, claims history, location, and the specific activities your business carries out.
Factors that affect your premium
- Industry and occupation. A builder pays more than a bookkeeper because the risk profile is fundamentally different.
- Annual revenue or turnover. Higher revenue generally means greater exposure and higher premiums.
- Cover level (sum insured). Moving from $1,000,000 to $5,000,000 of cover does not increase your premium fivefold. The incremental cost of higher cover is often modest.
- Claims history. Previous claims or a pattern of incidents will increase premiums.
- Number of employees. More people working under your business creates greater exposure.
- Business activities. The specific nature of your work matters. A painter faces different risks than a scaffolder, even though both are tradies.
How Much Cover Do You Need?
Public liability cover levels in New Zealand generally run from $1,000,000 for low-risk sole traders and home-based businesses, to $2,000,000 for most small businesses, $5,000,000 for tradies, builders, hospitality and event organisers, and $10,000,000 or more for larger construction firms. In construction, $5,000,000 is increasingly the standard minimum.
| Cover Level | Suited To |
|---|---|
| $1,000,000 | Low-risk sole traders, home-based businesses, market stall operators |
| $2,000,000 | Most small businesses, cleaners, personal trainers, small retailers |
| $5,000,000 | Tradies, builders, hospitality businesses, event organisers |
| $10,000,000+ | Larger construction firms, businesses working on high-value properties, those with contractual requirements for higher cover |
Many commercial contracts and tender documents specify a minimum level of public liability cover. In the construction sector, $5,000,000 is increasingly the standard minimum. Some government contracts require $10,000,000 or more.
If you work as a subcontractor, check the main contractor's requirements before selecting your cover level. Being underinsured is only marginally better than being uninsured if a claim exceeds your policy limit.
Public Liability vs Professional Indemnity vs Statutory Liability
Public liability covers injury to third parties and damage to their property, professional indemnity covers financial loss caused by professional errors, advice or omissions, and statutory liability covers fines, penalties and legal costs from regulatory breaches prosecuted by bodies such as WorkSafe. Many New Zealand businesses need more than one of the three.
| Public Liability | Professional Indemnity | Statutory Liability | |
|---|---|---|---|
| What it covers | Injury to third parties, damage to third-party property | Financial loss caused by professional errors, advice, or omissions | Fines, penalties, and legal costs from regulatory breaches |
| Typical claimant | Customer, member of the public | Client | Government regulator (e.g., WorkSafe) |
| Example | Customer slips on wet floor in your shop | Accountant provides incorrect tax advice costing client $50,000 | WorkSafe prosecutes you for a health and safety breach |
| Who needs it | Almost all businesses with public contact | Professional service providers, consultants, advisers | All employers (protects against H&S fines) |
Many businesses need more than one type of liability cover. A building consultancy, for example, would typically carry public liability (for site visits), professional indemnity (for design and advice work), and statutory liability (as an employer). These can often be bundled into a single business insurance package.
Real-World Claim Examples
Public liability claims in New Zealand commonly involve property damage and injury to members of the public. Typical scenarios include a failed plumbing fitting that floods a commercial kitchen and destroys $12,000 of stock and equipment, a market gazebo blown into a passer-by, a slip at a bootcamp that damages a participant's laptop, and overspray that ruins a neighbour's car.
Scenario 1: The leaking pipe. A plumber installs a new fitting in a commercial kitchen. Three days later, the fitting fails, flooding the kitchen and destroying $12,000 worth of stock and equipment. The restaurant owner claims against the plumber's public liability policy. The insurer covers the $12,000 property damage plus $3,500 in legal costs. Without cover, the plumber pays out of pocket.
Scenario 2: The market stall collapse. A vendor's gazebo at a weekend market is caught by a gust of wind and strikes a passer-by, causing a head injury. While ACC covers the person's medical costs, the vendor faces a claim for $8,000 in exemplary damages and legal defence costs of $15,000. Their public liability policy covers both.
Scenario 3: The gym floor. A personal trainer running a bootcamp session in a rented hall fails to clean up a water spill. A participant slips and damages their laptop and phone, totalling $4,500. The trainer's public liability policy covers the property damage claim.
Scenario 4: The painting contractor. A painter accidentally sprays exterior paint across a neighbour's car, causing $6,000 in damage. The neighbour claims against the painter's business. The public liability policy covers the cost of repainting the vehicle.

Tips for Managing Your Public Liability Insurance
Managing a public liability policy well means reviewing cover annually as turnover grows, telling the insurer about changes such as new services, new industries or new staff, since failing to disclose material changes could void cover, documenting incidents with photographs and witness details, understanding the excess you pay, and reading the exclusions in the policy wording.
- Review your cover annually. As your business grows, your exposure changes. A policy that was adequate when you were turning over $100,000 may not be sufficient at $500,000.
- Keep your insurer informed. If your business activities change, for example you start offering a new service, working in a new industry, or hiring staff, let your insurer know. Failing to disclose material changes could void your cover.
- Document everything. If an incident occurs, photograph the scene, collect witness details, and report it to your insurer promptly. Even if no claim is made immediately, having a record is valuable.
- Understand your excess. Most public liability policies have an excess (the amount you pay before the insurer covers the rest). Know what yours is and factor it into your financial planning.
- Read the exclusions. Every policy has them. Make sure you understand what is not covered so there are no surprises at claim time.
Frequently Asked Questions
Is public liability insurance a legal requirement in New Zealand?
No. There is no law in New Zealand that requires businesses to hold public liability insurance. However, it is a practical necessity for most businesses. Many clients, landlords, and main contractors require proof of public liability cover before they will work with you. Without it, you are personally or corporately liable for the full cost of any claim.
Does ACC replace the need for public liability insurance?
No. ACC covers personal injury to individuals, but it does not cover property damage, legal defence costs, or exemplary damages. If your business damages a client's property or you face legal action, ACC will not help. Public liability insurance and ACC levies serve entirely different purposes. For more on how ACC works alongside private insurance, see our guide on ACC vs private insurance.
How much public liability cover do I need as a tradie?
Most tradies in New Zealand carry between $2,000,000 and $5,000,000 of public liability cover. If you work as a subcontractor on construction sites, $5,000,000 is increasingly the standard minimum required by main contractors. For tradies working on high-value residential or commercial properties, $10,000,000 may be appropriate. Your business insurance adviser can help you assess the right level based on your specific trade and contracts.
Can I get public liability insurance as a sole trader?
Yes. Public liability insurance is available to sole traders, partnerships, companies, and trusts. As a sole trader, you are personally liable for claims against your business, which makes public liability cover particularly important. Low-risk sole trader occupations sit at the cheapest end of the public liability market, well below what a tradie or an event organiser pays for the same cover level.
What is the difference between public liability and general liability insurance?
In the New Zealand market, these terms are often used interchangeably. "General liability" is more common in the United States. In NZ, the standard term is "public liability." Some insurers package public liability together with products liability and call it "general liability" or "broadform liability." The underlying cover is similar, but always check the policy wording to understand exactly what is included.
Does public liability insurance cover me if I work at a client's home or premises?
Yes. Public liability insurance covers your business activities regardless of where they take place, whether at your own premises, a client's home, a construction site, or a public venue. This is one of the primary reasons the cover is so important for self-employed tradespeople and service providers who regularly work on other people's property.
Next Steps
Public liability insurance is a foundational piece of business protection in New Zealand. For most businesses, it is affordable, straightforward to arrange, and essential for protecting against claims that could otherwise cause serious financial harm.
If you are starting a business or reviewing your existing cover, take the time to assess your exposure. Consider the nature of your work, the value of the property you interact with, and any contractual requirements from clients or main contractors.
