Is business insurance required by law in New Zealand?

Most business insurance is not legally mandatory in New Zealand. The exceptions are motor vehicle third-party cover (compulsory under the Land Transport Act) and ACC levies (paid via Inland Revenue). Public liability, professional indemnity, statutory liability and employer liability insurance are all voluntary, but client contracts, landlords and licensing bodies frequently require them. WorkSafe duties under HSWA 2015 apply regardless of whether you carry insurance — insurance does not satisfy the duty, it covers the financial consequences of breach.

Does insurance cover WorkSafe NZ fines under HSWA 2015?

Statutory liability insurance can cover the legal defence costs and (where insurable) reparation orders made by the District Court following a HSWA prosecution. Fines for reckless conduct under section 47 of the Act are generally not insurable in New Zealand because allowing insurance to absorb a regulatory penalty would defeat the deterrent purpose of the penalty. The defence costs alone can run into six figures, which is why statutory liability cover exists separately from public liability and professional indemnity.

What is a PCBU under the Health and Safety at Work Act 2015?

A PCBU is a Person Conducting a Business or Undertaking. The term captures sole traders, companies, partnerships, and most other forms of business in New Zealand. WorkSafe NZ summarises PCBU duties at worksafe.govt.nz. The primary duty under section 36 of HSWA 2015 is to ensure, so far as is reasonably practicable, the health and safety of workers and other people influenced by the work.

Do sole traders have HSWA duties?

Yes. A sole trader is a PCBU under HSWA 2015. The scope of duties scales with the risk of the work, not the size of the business. A sole-trader builder on a residential site has the same primary duty as a large construction firm — to ensure work is done so far as is reasonably practicable without exposing anyone to risk. Sole traders also have a duty to themselves under section 36(2).

What is the difference between public liability, employer liability, and statutory liability insurance?

Public liability covers civil claims by third parties (members of the public, customers, other businesses) for injury or property damage. Employer liability covers civil claims by your own workers for harm not fully addressed by ACC — for example exemplary damages or stress-related claims. Statutory liability covers regulatory consequences (legal defence, reparation orders, some fines) under acts like HSWA 2015. A workplace incident can trigger all three depending on who is hurt and who brings the claim.

Where do I find official WorkSafe NZ guidance on PCBU duties?

WorkSafe NZ publishes its primary guidance at worksafe.govt.nz. The PCBU duties page is at worksafe.govt.nz/managing-health-and-safety/businesses/general-requirements-for-workplaces/pcbu/. The legislation itself sits on the Parliamentary Counsel Office website at legislation.govt.nz/act/public/2015/0070/latest/.

WorkSafe NZ Health & Safety + Business Insurance — How HSWA 2015 Interacts With Your Cover

The regulator and the statute, in one paragraph

WorkSafe New Zealand is the workplace health and safety regulator established under the WorkSafe New Zealand Act 2013. The substantive duties WorkSafe enforces sit in the Health and Safety at Work Act 2015 (HSWA), in force since 4 April 2016. HSWA replaced the old Health and Safety in Employment Act 1992 with a broader duty model: it doesn't only apply to "employers" with "employees", it applies to any Person Conducting a Business or Undertaking (a PCBU) and to all workers, however engaged. WorkSafe's operational guidance for PCBUs lives at worksafe.govt.nz. Read these primary sources alongside this guide — they are the source of truth, this page is a navigation aid.

The primary duty (section 36)

Section 36 of HSWA imposes the primary duty of care: a PCBU must ensure, so far as is reasonably practicable, the health and safety of:

Workers engaged or caused to be engaged by the PCBU, while they are at work
Workers whose activities in carrying out work are influenced or directed by the PCBU
Other persons (members of the public, visitors, contractors' workers) who could be put at risk by the work

"Reasonably practicable" is defined in section 22 — it weighs the likelihood and severity of harm against the availability and cost of ways to eliminate or minimise it. The Act explicitly says cost cannot be the only reason for not eliminating a risk where the risk is serious. WorkSafe's enforcement decisions consistently treat documented risk assessment plus implemented controls as the evidence that a PCBU has met its section-36 duty.

Officers' due diligence (section 44)

If you are an officer of a PCBU — a director, partner, or someone exercising significant influence over management — section 44 of HSWA imposes a personal due-diligence duty. Officers must take reasonable steps to acquire and keep up-to-date knowledge of work health and safety matters, gain an understanding of the operations and hazards involved, ensure appropriate resources and processes are in place, ensure there are processes for receiving and considering information about incidents, and verify the resources and processes are being used. WorkSafe has prosecuted officers personally; this is not a vicarious-liability shortcut.

What WorkSafe enforces, and how

WorkSafe has a graduated enforcement toolkit:

Improvement notice / prohibition notice — issued on inspection; requires action or stops work until risk is addressed
Infringement notice — administrative penalty for specified breaches, no court
Enforceable undertaking — alternative to prosecution where the PCBU commits to specific corrective measures, often community benefit projects
Prosecution — for the more serious offences under sections 47, 48 and 49

The prosecution offences are tiered by mental state: section 47 covers reckless conduct exposing a person to risk of death or serious injury (the most serious); section 48 covers failure to comply with a duty that exposes a person to risk of death or serious injury; section 49 covers any other failure to comply with a duty. The maximum penalties scale up sharply between tiers. The current statutory maxima are set out in HSWA itself — see sections 47-49 for the current figures.

How business insurance interacts with HSWA

This is the part most NZ business owners get wrong. Insurance does not discharge the section-36 duty. Insurance covers the financial consequences of an incident — it does not replace controls, training, risk assessment or supervision. With that framing fixed, three insurance products commonly come into play after a workplace incident:

1. Public liability insurance

Covers civil claims by third parties (members of the public, customers, other businesses) for personal injury or property damage caused by your business activity. In New Zealand, ACC absorbs most personal-injury compensation, so public liability claims tend to involve property damage, economic loss, or harm where ACC's no-fault scheme doesn't fully apply (overseas claimants, mental injury without physical cause, etc.). A workplace incident that injures a visitor or contractor on your site can trigger a public liability claim.

2. Employer liability insurance

Covers civil claims by your own workers for harm that falls outside ACC's no-fault cover. ACC covers personal-injury treatment and rehabilitation, but workers can still sue for exemplary damages (where conduct was outrageous), and for stress, harassment or gradual-process injuries that ACC declines. The Employment Court's exemplary-damages awards in workplace-harm cases sit alongside, not instead of, ACC. Employer liability fills this civil-claim gap.

3. Statutory liability insurance

Covers the regulatory consequences of a HSWA breach: legal defence costs in the WorkSafe prosecution, reparation orders made by the court under section 152, and (in some policies) the insurable portion of fines. The defence-cost line is the most material — even an enforceable-undertaking outcome can require six figures of legal advice to reach. The general principle in NZ law is that fines for reckless or deliberate conduct are not insurable (allowing insurance to absorb the penalty would defeat its deterrent purpose); reparation orders to victims, and defence costs, generally are insurable. Always check the wording.

The one incident, three policies problem

A single workplace incident can simultaneously trigger:

A WorkSafe investigation → statutory liability response
An exemplary-damages claim by the injured worker → employer liability response
A property-damage or third-party-injury claim → public liability response

If you only carry one of the three, the other two financial exposures are uninsured. This is the structural reason most small NZ businesses with employees carry a combined liability package rather than picking one product in isolation. Talk to a licensed adviser about which combination matches your risk profile — Evolve Group (FSP711891) operates this site.

Reasonable practicability and the underwriting view

Underwriters reading a statutory liability quote application look for the same evidence WorkSafe inspectors look for: documented risk assessment, hazard register, training records, near-miss reporting, officer involvement. A business that can produce these documents typically gets a quicker, cleaner quote; a business that cannot is often declined or quoted with significant exclusions. The compliance work and the insurability work are the same work — done once, they both improve.

Notifiable events and the 24-hour duty

Sections 23 to 25 of HSWA require a PCBU to notify WorkSafe as soon as possible after a notifiable event (death, notifiable injury or illness, notifiable incident). Notification is via WorkSafe's online form at worksafe.govt.nz/notifications. The PCBU must also preserve the incident site until WorkSafe authorises disturbance. The 24-48 hours after a notifiable event is where business owners often make insurance-coverage mistakes — engaging a lawyer or PR firm before notifying their insurer can void cover. The first call after notifying WorkSafe should be to your insurance adviser.

Quick FAQ

Does my business need WorkSafe to be involved before I claim on insurance?

No. A civil claim from an injured visitor or worker can be notified to your liability insurer immediately. A regulatory matter (WorkSafe investigation, prosecution, infringement notice) triggers your statutory liability cover. These notifications are independent — notify your insurer as soon as you become aware of any potential claim, regardless of WorkSafe status.

Can I be personally liable if my company is the PCBU?

Yes, if you are an officer under section 18 of HSWA. The officer due-diligence duty in section 44 is a personal duty and can result in personal prosecution. Many statutory liability policies extend cover to officers in their personal capacity — confirm with your adviser.

What records does WorkSafe expect a small business to keep?

WorkSafe publishes simple-language guidance for small businesses at worksafe.govt.nz/managing-health-and-safety/businesses/small-business/. At minimum: a hazard or risk register, evidence of training and induction, an incident/near-miss log, and records of any maintenance/inspection on plant or equipment.

Are WorkSafe penalties tax-deductible?

Inland Revenue's general position is that fines and penalties are not tax-deductible — see ird.govt.nz for the current operational statement on deductibility of penalties. Legal defence costs and insurance premiums may be deductible if incurred in deriving assessable income; check with your accountant.
