Running a business in New Zealand means managing real financial risk - from client disputes to damaged equipment to a slip-and-fall on your premises. The right business insurance puts a financial safety net under those risks so a single claim does not derail what you have built. This guide walks through each major cover type and helps you work out what you actually need.
This guide is general information for NZ businesses, not financial or insurance advice. Cover, limits and exclusions vary between insurers - always read the policy wording and consider talking to a licensed insurance broker or financial adviser before you buy.

Public liability insurance
Public liability insurance covers you if a third party - a client, a member of the public or their property - suffers loss because of your business activities. It pays for compensation claims and your legal defence costs. A concreter who damages a neighbour's fence, a cleaner who breaks a client's ornament, or a consultant whose visitor trips on a power cord - public liability responds to all of these. Most NZ contracts and commercial leases require it, with common minimums ranging from $1 million to $5 million. Small businesses of almost every type should hold it as a baseline cover.
Professional indemnity insurance
Professional indemnity insurance covers claims that your professional advice, design or service caused a client a financial loss. It is not just for doctors and lawyers - it matters for accountants, IT consultants, engineers, marketers, architects and many tradespeople who specify products or provide design input. Defence costs alone in a professional dispute can reach tens of thousands of dollars, even when you have done nothing wrong. Most professional bodies and many client contracts require it as a condition of engagement.
Tools and portable equipment insurance
Your tools are your livelihood. Tools insurance covers loss, theft or accidental damage to hand tools, power tools, test equipment and other portable gear while on site, in your vehicle or in storage. Tradies who rely on specialist equipment - electricians, plumbers, builders, mechanics - are the core market, but any contractor who carries gear to client sites benefits. Some policies extend to hired-in plant and equipment as well. Note that ACC covers you if you are personally injured on the job, but it does not replace your tools.
Business contents and property insurance
This cover protects the physical assets inside your business premises - office furniture, computers, stock, fit-out and fixtures - against fire, water damage, theft and other insured events. If you lease a commercial space, the building itself is usually the landlord's responsibility, but everything inside is yours. A break-in that clears out your retail stock or a burst pipe that soaks your server room can mean five- or six-figure replacement costs. Check whether the policy covers contents at replacement value or depreciated value - the difference matters at claim time.
Commercial vehicle insurance
Personal car insurance typically does not cover your vehicle when it is being used for business purposes. Commercial vehicle insurance fills that gap, covering your vehicle for physical damage and third-party liability while you are on the job. It can cover cars, utes, vans, trailers and trucks. If you or your team drive to client sites, carry goods or tow equipment, you need a policy that explicitly includes business use. Some insurers also offer fleet policies that bundle multiple vehicles under one premium.
Business interruption insurance
If a fire, flood or other insured event forces you to close temporarily, business interruption cover replaces the income you lose while you cannot trade. It can also cover increased operating costs - for example, hiring temporary premises while your own are being repaired. It generally only pays out where there is also a claim under your property or contents policy, because it is triggered by a covered physical event. Businesses with employees on salary, ongoing rent commitments or loan repayments benefit most, because those fixed overheads keep running whether you can trade or not.
Statutory liability insurance
Statutory liability covers fines, penalties and defence costs if your business unintentionally breaches an NZ statute - the Health and Safety at Work Act, the Fair Trading Act, the Resource Management Act and others. It does not cover deliberate breaches or criminal fines, but it does cover the cost of defending an allegation even if you are ultimately found to have done nothing wrong. The risks of not having business insurance in this area can be significant - WorkSafe investigations and prosecutions are not cheap to defend.
Employers liability insurance
In New Zealand, ACC covers employees for personal injury at work - you do not need a separate employers liability policy for physical injury claims the way some overseas jurisdictions require. However, NZ employers can still face claims under employment law: personal grievances, unjustified dismissal, discrimination and harassment allegations. Employers liability insurance (sometimes called employment practices liability) covers your legal costs and any awards in those cases. Any business with staff - including part-time or casual workers - should consider it.
Cyber liability insurance
Cyber liability covers the costs of a data breach or cyber attack - notifying affected customers, forensic investigation, regulatory response, business interruption caused by a system outage, and third-party claims if your breach compromises client data. The Privacy Act 2020 puts real obligations on NZ businesses to protect personal information, and a breach response can quickly outpace what most small businesses can absorb from cash flow. Any business that holds customer records, processes payments or stores data online carries meaningful cyber exposure.
Income protection insurance
Income protection is personal cover for you as a business owner or sole trader - if illness or injury stops you working, it pays a monthly benefit to replace a portion of your income. ACC covers accidents, but it does not cover illness or non-accident conditions that keep you away from work for months. If your business depends on your personal labour and you have no sick leave or employees to carry the load, an extended period without income can be devastating. This cover is typically taken out in your personal name rather than the business name.
How to choose the right cover for your business
There is no single answer to what insurance you need - it depends on your industry, the contracts you sign, whether you have staff, and what assets or income you need to protect. A good starting point is to think about your three or four biggest financial risks: losing a key piece of equipment, a client suing over a mistake, a fire shutting your premises, or a serious illness. Match covers to those risks rather than buying everything at once.
Read the business insurance by profession guide to see what cover is typical for your trade or role. If you are in construction or project-based work, contract works insurance may also belong on your list. When comparing policies, pay close attention to limits, excesses and exclusions - not just the premium. A cheap policy with a high excess and a long list of exclusions may leave you exposed at the exact moment you need cover most. The business.govt.nz website also has useful general guidance on managing business risk.

Frequently asked questions
What business insurance do most NZ businesses start with?
Public liability is the most common first policy for NZ businesses, because many clients and commercial leases require it and the risk it covers - injuring someone or damaging their property - applies to almost every type of work. Tradespeople typically add tools insurance at the same time. Professional services businesses usually prioritise professional indemnity alongside public liability.
Do I need professional indemnity if I give advice?
If you charge for advice, design, recommendations or professional services of any kind, professional indemnity is worth serious consideration. A client who suffers a financial loss because of something you told them can claim against you - and defending that claim, even if you win, costs money. Many professional associations and government contracts require it as a condition of membership or engagement.
Is public liability compulsory in NZ?
There is no general law in New Zealand that requires businesses to hold public liability insurance. However, many commercial leases, client contracts and industry registrations require it as a condition, so in practice most businesses cannot operate without it. Minimum limits commonly required by contracts range from $1 million to $5 million depending on the work involved.
Can I bundle covers into one policy?
Yes - many insurers offer combined business insurance packages that roll public liability, contents, business interruption and other covers into a single annual premium. This is often more cost-effective than buying separate policies and means one renewal date and one insurer to deal with at claim time. Online comparison platforms let you see both individual and bundled options side by side so you can weigh up the cost difference.
Does ACC replace business insurance in NZ?
ACC only covers personal injury from an accident - it pays for medical treatment and some loss of earnings for the injured person. It does not cover damage to property, loss of tools or equipment, liability claims from clients, or income lost due to illness. New Zealand businesses still need commercial insurance for all of those risks, and ACC cover for injuries does not reduce your need for statutory liability or public liability policies.
