ACC for Marine Injury + Boat Insurance — How NZ's Two-Scheme Model Works

New Zealand operates two distinct schemes for marine incidents. The Accident Compensation Corporation (ACC) is the no-fault scheme that covers personal injury — medical treatment, rehabilitation, lost income, and lump-sum payments — regardless of who was at fault. Boat insurance is the contract-of-indemnity scheme that covers vessel damage, third-party property damage, and other financial losses. Most NZ boat owners need a working understanding of both, because most marine incidents trigger both — and the rules about which scheme pays for what aren't always intuitive. This guide explains how the two schemes work together when a marine accident causes both injury and damage.

ACC — what it is + what it pays for

ACC is NZ's universal no-fault accident-compensation scheme, established by the Accident Compensation Act 2001. Funded by levies on employers, employees, motor-vehicle owners, and the general taxpayer, it provides:

• Treatment costs — GP visits, specialist consultations, surgery, physiotherapy, ambulance, helicopter evacuation.
• Weekly compensation — for earners who can't work due to injury, ACC pays a percentage of pre-injury earnings.
• Rehabilitation — return-to-work programmes, home modifications, equipment.
• Lump-sum payments for serious injury (independence allowance, lump-sum compensation).
• Death benefits for surviving partners, children, and other dependants.

The trade-off NZ made when ACC was established (in the 1970s): no-fault cover for everyone, in exchange for restricting the right to sue for personal injury. Section 317 of the Accident Compensation Act 2001 limits the ability to bring common-law personal injury claims arising from accidents covered by ACC. This shapes the entire NZ marine-injury landscape.

What ACC covers in a marine context

ACC covers personal injury from any accident in NZ — including marine accidents in NZ waters. Examples covered:

• Skipper or passenger thrown overboard and injured
• Crew member crushed against a winch or boom
• Person injured in a vessel-vessel collision
• Drowning incident (where revived) and post-incident treatment
• Hypothermia treatment
• Cuts, fractures, burns from equipment failure
• Sun, heat, or cold exposure illness
• Injury during launch / retrieve (slip on ramp, trapped finger on trailer winch)

ACC also covers boating-injury rehabilitation regardless of fault — so the skipper who caused the accident is covered, and so is the passenger who was injured by the skipper's mistake. Both can claim ACC treatment and weekly compensation.

What ACC does NOT cover in a marine context

• Damage to the boat itself — that's boat insurance.
• Damage to other people's property (other boats, marina infrastructure, ramps, fishing gear) — that's the third-party liability section of your boat insurance.
• Loss of fishing catch, recreational equipment, or personal effects on the boat — possibly covered under your boat insurance's personal-effects extension or home contents, depending on the policy.
• Loss of income from inability to use the boat commercially — that's commercial marine business-interruption cover, not pleasure-craft cover.
• Mental injury without a physical cause — ACC's coverage of mental injury is narrower; covered only where it arises from a physical injury or specific qualifying event (e.g. sexual assault, witnessing a serious accident). General PTSD from a non-traumatic boating experience isn't covered.
• Illness that wasn't caused by an accident — e.g. seasickness leading to dehydration generally isn't an "accident" for ACC purposes.

Personal injury vs property damage — the typical marine incident split

Consider a typical NZ marine incident: a launch collides with a moored vessel in fog. Several outcomes:

• Skipper of the moving launch hits their head on the wheelhouse and needs stitches. ACC pays for treatment + any time off work. No fault assessment.
• The launch has hull damage. Boat insurance pays under the hull section, subject to excess.
• The moored vessel has hull damage. The launch's third-party liability section covers the damage to the moored vessel.
• The moored vessel's owner finds out months later about damage and lodges a claim. Standard third-party process via the launch's insurer.
• A passenger on the moored vessel was below decks and was injured by the impact. ACC covers their treatment, regardless of who's at fault.
• The passenger wants compensation for "pain and suffering" beyond ACC. Section 317 of the ACC Act bars most personal-injury claims at common law, but there are narrow exceptions (notably exemplary damages for outrageous conduct, and certain mental-injury claims). The launch operator's third-party liability cover typically doesn't pay for ACC-covered personal injury.

The interaction matters because policyholders sometimes expect their boat insurance's third-party liability section to pay for the injured passenger's loss-of-amenity or lost wages. In NZ it usually doesn't — that's the ACC scheme. The third-party liability section is mostly for property damage and other-vessel damage.

Exceptions — when boat insurance liability might still bite

A few situations where the boat insurance third-party liability section does engage even though ACC is the primary personal-injury scheme:

• Overseas injury — if the incident occurs outside NZ (e.g. on a Pacific extension), ACC may not apply and the foreign legal regime takes over. Local personal-injury rules can apply, and your boat insurance's third-party liability + medical extension matter.
• Non-NZ-resident victim — partial coverage in some cases. Treatment in NZ generally still ACC-covered for visitors; longer-term wage loss may not be.
• Mental injury without qualifying physical cause — narrow exception under ACC. May leave room for a common-law claim that the boat insurance third-party section could cover.
• Exemplary damages — for outrageous conduct, common-law claims for exemplary damages (punitive damages) remain possible. Your boat insurance's third-party liability may or may not cover these depending on the policy wording.
• Commercial marine — different rules. Commercial passenger vessel operators have additional obligations under Maritime Rule Part 40A + Health and Safety at Work Act 2015. Commercial third-party liability cover is generally broader.

Documentation in a marine-injury incident

If anyone is injured in a marine incident, key steps:

1. Get medical attention immediately. Hypothermia, head injuries, drowning aftermath — all time-critical.
2. Tell the medical provider the injury is from a boating accident. Triggers ACC funding for the treatment.
3. Note the incident details — date, time, location, vessels involved, witnesses, weather, sea state, what happened. Critical for both ACC and insurance.
4. Notify your boat insurer within the standard timeframe — same notification regardless of whether ACC is the personal-injury scheme.
5. Report serious incidents to RCCNZ / Coastguard / Maritime NZ if required (most marine fatalities + serious injuries trigger investigation).
6. Photograph the scene + damage for both ACC and the insurance claim.

Cost implications for the boat owner

Because ACC is funded through general levies (motor-vehicle levies, employee levies, taxpayer), there's no per-claim premium impact on you specifically. But there are two indirect cost flows:

• ACC's recreational-craft levy review — ACC periodically reviews whether recreational boating should attract a specific levy (similar to motor-vehicle levy). To date, recreational craft don't pay a dedicated ACC levy, but the position is reviewable.
• Your boat insurance premium — most NZ marine policies include a medical-expenses / accidental-injury extension that pays for the gaps ACC doesn't cover (e.g. private hospital, overseas medical evacuation). The premium reflects the size of this extension.
