Public Liability Insurance
Protect your business from third-party injury and property damage claims. Essential coverage for New Zealand businesses operating in public spaces or on client premises.
What Is Public Liability Insurance?
Public liability insurance protects your business when a third party — a customer, a supplier, a member of the public, or anyone who is not your employee — suffers an injury or has their property damaged as a result of your business activities.
If that person makes a claim against your business, your public liability policy covers the cost of compensation payments and the legal fees involved in defending the claim, up to your policy limit.
In New Zealand, this is one of the most common forms of business insurance. Whether you operate from a fixed premises, travel to client sites, or work in public spaces, there is always a risk that someone could be injured or have their property damaged because of something your business does or fails to do.
Public liability insurance is sometimes referred to as "general liability" or "third-party liability" insurance. Regardless of the name, it covers the same core risk: your legal liability for bodily injury or property damage to people outside your business.
What Does Public Liability Insurance Cover?
Third-Party Bodily Injury
Compensation and medical costs if a customer, visitor, or member of the public is injured because of your business operations. Illustrative example: a customer trips over an extension cord in your workshop and breaks their wrist.
Third-Party Property Damage
Covers damage you cause to someone else's property during your work. Illustrative example: a painter accidentally spills a bucket of paint on a client's expensive carpet.
Legal Defence Costs
Solicitor fees, court costs, and expert witness expenses if a claim goes to court — even if the claim turns out to be unfounded. Legal defence can be expensive on its own, often running into tens of thousands of dollars.
Products Liability
Many public liability policies include cover for injury or damage caused by products you sell, supply, or distribute. Check your policy wording — this is sometimes a separate section or optional extension.
Advertising Injury
Some policies extend to cover claims of defamation, libel, or slander arising from your business advertising or promotional activities.
Tenant's Liability
If you lease your business premises, many policies cover accidental damage you cause to the landlord's property beyond normal wear and tear.
What's NOT Covered by Public Liability Insurance
- Professional advice errors — mistakes in your professional advice or services require professional indemnity insurance
- Employee injuries — injuries to your own staff are handled by ACC and employer's liability insurance
- Intentional or criminal acts — deliberate damage or illegal activity is excluded from all insurance policies
- Your own property or assets — damage to your own tools, equipment, or premises requires separate material damage cover
- Faulty workmanship (the work itself) — the cost to redo or repair your own defective work is typically excluded, though resulting damage to other property may be covered
- Motor vehicle incidents — these are covered by motor vehicle insurance, not public liability
How Much Does Public Liability Insurance Cost in NZ?
The cost of public liability insurance depends on your industry, revenue, and the level of cover you need. Below are indicative monthly premium ranges for common business types. Actual premiums vary — your insurer will assess your specific circumstances.
| Industry | Indicative Monthly Cost | Typical Cover Level |
|---|---|---|
| Tradies (builders, plumbers, electricians) | $15 - $40/month | $1M - $2M |
| Retail shops | $20 - $50/month | $1M - $5M |
| Consultants and office-based businesses | $15 - $35/month | $1M - $2M |
| Hospitality (cafes, restaurants, bars) | $25 - $60/month | $2M - $10M |
| Cleaners | $12 - $30/month | $1M - $2M |
| Personal trainers and fitness | $15 - $35/month | $1M - $2M |
| Event organisers | $30 - $80/month | $5M - $10M |
Factors That Affect Your Premium
- - Industry and risk level: A roofer pays more than an office-based consultant because the physical risk is higher
- - Annual revenue: Higher revenue generally means higher premiums, as it indicates more business activity and greater exposure
- - Number of employees: More staff typically means more potential for incidents
- - Coverage limit: A $5M policy costs more than a $1M policy
- - Claims history: Previous claims or a history of incidents may increase your premium
- - Excess (deductible): Choosing a higher excess reduces your premium, but means you pay more out of pocket per claim
Who Needs Public Liability Insurance?
Any business that has contact with the public, visits client sites, or sells physical products should consider public liability insurance. Even if you work from home, you may have clients visit or you may attend meetings at other premises.
The following types of businesses commonly carry public liability insurance in New Zealand:
Is Public Liability Insurance Compulsory in NZ?
Public liability insurance is not legally required for most businesses in New Zealand. Unlike some countries, there is no general law mandating that all businesses carry this cover.
However, there are many situations where it is effectively required:
Government and council contracts
Most central government agencies and local councils require contractors to hold a minimum level of public liability insurance (often $1M to $5M) before awarding contracts.
Commercial leases
Many landlords include a requirement for public liability insurance in the lease agreement before tenants can occupy commercial premises.
Client and principal contractor requirements
Subcontractors working for larger firms are commonly required to provide a certificate of currency for public liability insurance before starting work.
Real estate and property access
Property managers and real estate agents may require tradespeople and service providers to show proof of public liability before allowing access to properties.
ACC vs Public Liability — What's the Difference?
New Zealand's ACC scheme covers personal injury costs (medical treatment, rehabilitation, lost wages) for the injured person. All businesses contribute to ACC through levies.
However, ACC does not cover:
- - Compensation for pain and suffering beyond what ACC provides
- - Property damage claims (ACC only covers personal injury)
- - Your legal defence costs
- - Claims for economic loss arising from the incident
While ACC significantly reduces the personal injury litigation environment in NZ compared to countries like the US or Australia, it does not eliminate your business's liability exposure entirely. Public liability insurance fills the gap that ACC does not cover.
Coverage Levels — How Much Do You Need?
Public liability insurance in NZ is typically available in coverage levels from $1 million to $20 million. The right level depends on your industry, client requirements, and risk profile.
$1 Million
Entry levelSuitable for sole traders and very small businesses with low foot traffic and minimal physical risk — such as home-based consultants or freelancers who occasionally visit client sites.
$2 Million
Most commonThe most commonly selected level for small businesses in NZ. Appropriate for tradies, cleaners, small retailers, and service businesses. Meets most standard contractual requirements.
$5 Million
Growing businessesAppropriate for businesses with higher public exposure — retail shops with significant foot traffic, hospitality venues, or contractors working on mid-size commercial projects. Often required for government contracts.
$10 Million
Medium businessesFor established businesses with multiple employees, larger commercial contracts, or higher-risk activities. Common for construction companies, event organisers, and businesses working in hazardous environments.
$20 Million
High risk / large contractsFor businesses involved in major infrastructure projects, high-risk construction, large public events, or those required by major clients or government agencies to carry higher limits.
If you are unsure what level to choose, check the contracts you hold or plan to bid on — many specify a minimum coverage level. Your insurance adviser can help you assess the appropriate limit for your situation.
How to Claim on Public Liability Insurance
If an incident occurs that may result in a claim, follow these steps. Acting promptly is important — most policies require you to notify your insurer as soon as reasonably practicable.
Ensure safety and document the incident
Make sure everyone is safe. Take photos of the scene, note the date, time, and circumstances. Collect contact details of any witnesses. Do not admit fault or liability at the scene.
Notify your insurer or broker
Contact your insurer or insurance broker as soon as possible. Most policies have a notification timeframe, and late notification can affect your cover.
Complete the claim form
Your insurer will provide a claim form. Fill it out accurately and completely, attaching all supporting documentation — photos, witness statements, invoices, and any correspondence from the claimant.
Cooperate with the investigation
Your insurer may appoint a loss assessor or investigator. Cooperate fully, provide any additional information they request, and do not negotiate directly with the claimant unless your insurer instructs you to.
Resolution and settlement
Your insurer will manage the claim through to resolution — whether that is a negotiated settlement, mediation, or court proceedings. Your legal defence costs are covered under the policy.
Public Liability vs Professional Indemnity Insurance
These two policies protect against different types of risk. Many businesses need both.
| Public Liability | Professional Indemnity | |
|---|---|---|
| Covers | Physical injury and property damage | Financial loss from professional errors |
| Triggered by | Physical incidents | Advice, services, or design errors |
| Policy type | Occurrence-based (usually) | Claims-made |
| Typical cost | $15 - $60/month | $25 - $120/month |
| Best for | Tradies, retailers, hospitality | Consultants, advisers, designers |

Frequently Asked Questions
How much does public liability insurance cost in NZ?
Public liability insurance in New Zealand typically costs between $15 and $60 per month for small businesses. Actual premiums vary based on your industry, revenue, number of employees, claims history, and the level of cover you choose.
Is public liability insurance mandatory in New Zealand?
Public liability insurance is not legally required for most NZ businesses. However, it is often contractually required by clients, landlords, and government agencies before you can work on their premises or win contracts.
What is the difference between public liability and ACC?
ACC covers personal injury costs for the injured person (medical bills, rehabilitation, lost wages). Public liability insurance covers your business's legal liability — the compensation you may owe to the injured party above and beyond what ACC provides, plus property damage claims and legal defence costs that ACC does not cover at all.
Does public liability insurance cover my employees?
No. Public liability insurance covers claims from third parties — customers, members of the public, and other people who are not your employees. For employee-related claims, you would need statutory liability insurance or employer's liability insurance.
Can I get public liability insurance with no claims history?
Yes. New businesses and sole traders can obtain public liability insurance. Insurers will assess your industry, projected revenue, and the nature of your work rather than requiring an existing claims history.
How quickly can I get public liability insurance?
Many standard public liability policies can be arranged within 24 to 48 hours. More complex businesses or higher coverage levels may take longer as the insurer assesses your specific risk profile.
