Sole Trader Insurance NZ: What a One-Person Business Needs

Sole trader insurance is not one product. It is a set of business covers, usually public liability, professional indemnity, tools and equipment, and a vehicle policy, chosen to suit what you do. No general law requires a sole trader to hold any of them. Clients, landlords and platforms often ask for a current certificate, and without a company between you and a claim, the loss lands on you personally.

In short

What clients and landlords ask sole traders for

  • A minimum limit named in the contract or tender
  • A certificate of currency for the lease or venue
  • Cover that matches the rules of your platform or franchise
  • Rules from your licensing or membership body, if you have one

Damage on a client site

With no company in between, the claim lands on you personally.

Advice that cost a client

Public liability does not respond to a bad recommendation.

Stolen or dropped gear

Your laptop or toolkit is not covered by liability insurance.

Work in a personal car

A personal policy may not respond to business use.

What these covers do not pay

  • Redoing your own faulty work. Damage it causes to someone else's property may be a different matter.
  • Your own laptop or toolkit under a public liability policy.
  • Advice or design errors under a liability policy. That is professional indemnity territory.
  • Your own time off if you are sick. ACC covers injury within limits, not illness.
  • Health and safety fines, which can never be insured (Health and Safety at Work Act 2015, s 29).

General information only. Whether a cover responds depends on the policy wording.

Which clause is in your contract?

  • Professional standard

    You agree to work with reasonable skill and care, or to a named industry standard. If the work falls short, that is the test a client may use against you.

    Covers to raise: Professional indemnity

    What it does not decide: It does not decide whether a claim for falling short is covered. Professional indemnity wordings differ on what is excluded, such as guarantees, fee disputes and known issues.

  • Own tools and plant

    The contract says you bring and look after your own tools, equipment or machinery, so damage or theft of them sits with you rather than the client.

    Covers to raise: Tools and equipment, Business vehicles

    What it does not decide: It does not decide whether those items are insured, on site or in a vehicle, or hired in. Contract works and public liability policies usually do not pick up your own tools.

  • Limitation of liability

    A cap on what you could owe the client if something goes wrong, often tied to your fees or a set figure. It can also exclude certain losses such as lost profit.

    Covers to raise: Professional indemnity, Public liability

    What it does not decide: It does not decide what your insurance pays. A cap in the contract may sit below or above your policy limit, and some claims, such as personal injury, may fall outside it.

General information, not legal advice. The full clause and the policy wording decide how it applies.

Check your certificate of currency against the contract

Check the insured name, limit and dates match the contract. The policy wording, not the certificate, decides what is covered. How a certificate of currency works

If something goes wrong

  • A hidden pipe

    A sole trader drilling into a client's wall hits a concealed water pipe and floods the room below.

    May respond: Public liability

    Have ready

    • Photos of the damage and the site
    • The job quote and invoice
    • Your policy schedule
    • The name and contact of the client
  • A report that cost a client

    A consultant's report contains an error, and the client says it led to a costly decision.

    May respond: Professional indemnity

    Have ready

    • The signed brief or contract
    • The report and any drafts
    • Emails with the client
    • The date you first heard of the complaint
  • Gear taken from the van

    A tradesperson's toolkit is stolen from a parked van overnight.

    May respond: Tools and equipment, Business vehicles

    Have ready

    • A police report
    • Receipts or a list of the tools
    • Photos of the vehicle and any forced entry
    • Where the van was parked and whether it was locked
  • A phishing payment

    A fake email changes a supplier's bank details and one payment goes to the wrong account.

    May respond: Cyber

    Have ready

    • The original and fake emails
    • Your bank's records of the transfer
    • Screenshots of anything unusual
    • A note of who had access to the account

Typical examples, not real claims. ACC deals with most injuries, so an injury claim is mostly about property and legal costs. Whether a claim is paid depends on the policy wording and the facts.

Why working alone changes the question

A sole trader and the business are the same legal person. If a client claims against the business, they are claiming against you. Our business insurance guide covers how structure affects it.

So the question is "what could one bad job cost me, and who pays?" A bookkeeper in a spare room and a mobile mechanic with a van are very different answers.

Working from home does not make the risk smaller. A home and contents policy usually excludes business equipment and client liability, so tell your insurer, and see home business insurance.

Do sole traders have to be insured?

Not by a general rule. Check these instead:

Being self-employed does not remove your health and safety duties. The Health and Safety at Work Act 2015 covers a person conducting a business "alone or with others" (section 17), and fines under the Act cannot be insured (section 29).

The covers a sole trader usually looks at

Public liability

Pays when you are legally liable for damage to someone else's property, or injury to a member of the public, plus legal defence costs. Because ACC bars most compensation claims for personal injury, NZ claims are mostly about property. See the public liability guide.

Professional indemnity

Responds when a client says your advice, design, report or error cost them money. Check the claims-made wording. See the professional indemnity guide.

Tools and equipment

Liability insurance does not cover your own laptop, camera or toolkit. See tool insurance, and ask about theft from an unattended vehicle.

Vehicle, cyber and the rest

A personal car policy may not respond to business use: business vehicle insurance. If you hold client data or pay by bank transfer, see cyber insurance. Statutory liability can contribute to defence costs but not health and safety fines, and business interruption has a narrow trigger.

What is usually not covered

Policies vary, so read the wording. Common exclusions:

Your income if you are sick or hurt is a separate decision: income protection for the self-employed, contractor insurance and business protection.

Starting points by type of sole trader

If you are Questions to start with
A tradesperson on client premises Public liability limit in the subcontract, tools, van. See tradie insurance
A consultant, designer or IT contractor Professional indemnity wording and limit, cyber, laptop cover
A mobile service such as cleaning or grooming Public liability at client sites, equipment, vehicle
A stallholder or market seller Venue certificate, stock and stall equipment
A gig or platform worker What the platform covers. See gig economy insurance

Getting a certificate your client will accept

Clients want a certificate of currency showing the policy type, limit and period. Have ready the insurance clause from the contract, a plain description of what you do, your turnover estimate, whether you use subcontractors, and any previous claims. Send the clause early, because underwriting time depends on the insurer.

Frequently Asked Questions

Do I need insurance as a sole trader in NZ?

No general law says so. Contracts, landlords, venues and some professional bodies often do, and a claim would fall on you personally.

Is public liability or professional indemnity better for a sole trader?

They cover different claims. Public liability is for property damage and injury to others. Professional indemnity is for financial loss from your advice or errors. Some businesses need both.

Can I insure myself as a sole trader if I work from home?

Home-based work can still need liability and equipment cover, especially if clients visit or you hold their data. Your home and contents policy may not cover business use, so ask your insurer.

Can I claim sole trader insurance as an expense?

Generally, liability and property covers are treated as business running costs, but life-type cover is treated differently. Check with your accountant or Inland Revenue.
