The risks of not having business insurance in NZ (and what it really costs)

Find out what really happens when a NZ business has no insurance - realistic dollar figures, concrete examples, and the cover that fixes each risk.

Running a business without insurance feels fine - right up until the moment it is not. The risks of not having business insurance are real, specific, and often far more expensive than a premium would have cost. Here is what those risks actually look like, in plain New Zealand terms.

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.

What "uninsured" really means

When people ask "do I need business insurance", they often assume someone else will pick up the tab if things go wrong. In New Zealand that is rarely true. There is no general law forcing most businesses to hold cover, but that does not mean you are protected if you skip it - it means the financial pain lands directly on you.

Types of business insurance range from public liability through to professional indemnity, tools cover, and cyber protection. Each one takes a specific risk off your plate. Without them, you carry every one of those risks yourself.

Risk 1 - A customer's property is damaged

You are a plumber finishing a bathroom refit. A fitting fails overnight and water floods the client's kitchen below - ruining cabinetry, flooring, and appliances. The repair bill lands at $28,000.

Without public liability insurance, that invoice is yours. You drain your business account, take on debt, or face debt collection. If you operate as a sole trader, your personal assets can be exposed too - there is no corporate veil protecting you.

Public liability insurance typically costs a few hundred dollars a year and covers exactly this kind of third-party property damage. Most commercial leases and main-contractor agreements in NZ require you to hold at least $1 million of cover, so skipping it may also block you from working with larger clients.

Risk 2 - A client sues you over bad advice

You are an accountant, consultant, or designer. A client acts on your work and loses money - or decides to blame you for a project gone sideways. They engage a lawyer and file a claim for $80,000.

Even if you did nothing wrong, defending yourself costs real money. A simple commercial dispute in NZ can rack up $15,000 to $40,000 in legal fees before any resolution. Without professional indemnity insurance, every dollar comes from your pocket.

Professional indemnity insurance covers your legal defence and any damages or settlement - which is why it is close to standard practice for anyone who sells expertise or advice for a living.

Risk 3 - Your tools are stolen

A tradie's ute broken into overnight is not a rare story in NZ. A full kit of power tools, laser levels, and specialist gear can represent $10,000 to $25,000 in value - most of it gone the moment someone smashes a window.

Without tools insurance, you replace everything out of pocket. And because you cannot work without your gear, the real cost is the replacement bill plus the income you lose while you wait.

Risk 4 - A fire or accident on a job site

You are a builder or electrician. An accident on site damages a structure, or a fire spreads from your work area. The damage runs to $120,000. WorkSafe may investigate too, adding legal and compliance costs on top of the repair bill.

A public liability policy - combined with contract works cover on larger projects - wraps both the property damage and the legal exposure into one package.

Risk 5 - A cyber breach leaks client data

You hold client names, email addresses, and payment details. A phishing email gets through and that data is exposed. Under the Privacy Act 2020, you may be required to notify affected individuals and the Privacy Commissioner. The cost of notifying clients and engaging an IT forensics firm can easily reach $20,000 to $50,000 for a small business.

Cyber liability insurance covers breach response costs, client notification, and business interruption from a cyber event.

What about ACC?

This is the most common misunderstanding for NZ business owners. ACC covers personal injury to people - if you or a worker gets hurt on the job, ACC helps with medical costs and lost earnings. That is genuinely valuable, and unique to New Zealand.

But ACC does not cover damage to someone else's property, theft of your tools, a client suing you for negligent advice, or your own business income if you cannot operate. An uninsured business in NZ pays for all of those things directly from its own pocket - the ACC safety net simply does not apply to them.

Is it a legal requirement?

There is generally no single NZ law that forces most businesses to hold insurance. But in practice, you often have little choice. Commercial leases routinely require public liability cover - commonly $1 million to $2 million. Main contractors on building sites require subcontractors to show proof before stepping on site. Client contracts in professional services often specify minimum indemnity limits.

Frequently asked questions

Is business insurance a legal requirement in New Zealand?

There is no single law requiring most NZ businesses to hold insurance. However, commercial leases, main-contractor agreements, and client contracts often require specific cover - such as public liability - before you can operate or sign. In practice, many businesses find they cannot work without it even if the law does not technically require it.

Doesn't ACC cover me?

ACC covers personal injury to people - a worker hurt on site, for example. It does not cover damage to someone else's property, theft of your tools, legal claims about your advice or services, or your own business income if you cannot operate. If you are wondering what happens if you don't have business insurance in NZ, these are the gaps that come back to hurt you.

How much does it cost to be uninsured?

It depends on what goes wrong. Realistic NZ scenarios include $28,000 for water damage to a client's property, up to $40,000 in legal fees defending a negligence claim, or $25,000 to replace stolen tools. In a worst case - a major fire or a significant liability claim - an uninsured business can face six-figure losses that are simply unrecoverable.

What is the single most important cover to have?

For most NZ businesses, public liability insurance is the foundation. It covers you when something you do causes damage to a third party - and it is the cover most commonly required by contracts and leases. If you sell advice or professional services, add professional indemnity alongside it.

Can I be sued personally if my business is not insured?

Yes. If you operate as a sole trader or in a partnership, there is no legal separation between you and your business. Personal assets including your home can be exposed to business debts and claims. Even operating as a company does not always protect directors if a court finds personal liability. Insurance is the practical protection against that exposure.
