Not Covered By Default
Boat insurance NZ
Is your vessel properly covered?
A boat sitting on a mooring or a trailer is still exposed to theft, storm damage, and marine liability risk. Kapi Insurance reviews hull insurance, outboard motor and inboard engine cover, trailer, and third-party liability policies from trusted insurers to find the cover that actually fits your vessel, your waters, and your budget.
What is boat insurance?
Boat insurance (also called marine insurance or pleasure craft insurance) combines hull insurance and marine liability cover to protect your vessel against physical damage, theft, fire, and your legal responsibility for damage caused to other boats, moorings, or marine property. Maritime NZ administers the Maritime Transport Act and oversees boating safety rules, but there is no law requiring recreational boat owners to carry insurance.
That said, most marinas and mooring facilities require proof of third-party marine liability cover before they will allocate a berth. Auckland's Westhaven Marina, Half Moon Bay, and facilities across Tauranga and Wellington all enforce this. If your boat collides with another vessel, damages a jetty, or sinks in a shared waterway, the costs fall on you without a policy in place. Salvage costs and wreck removal can run into tens of thousands of dollars, and that figure climbs fast for larger vessels or difficult recovery locations.
Policies typically cover the hull, outboard motor or inboard engine, permanently attached equipment, and electronics. Additional options include trailer cover, personal effects on board, towing and salvage costs, and extended cruising range for trips beyond standard coastal waters. The right level of cover depends on the vessel type, how you use it, and where you keep it.
Types of boat insurance available
Boat insurance comes in three levels: Third Party only, Third Party Fire and Theft, and comprehensive (full hull insurance). Whether you own a trailer boat, launch, powerboat, yacht, or catamaran, the right choice depends on your vessel's value, where you keep it, and how much risk you are prepared to carry yourself.
Third Party only
Typically covers your marine liability if your boat damages another vessel, a marina structure, a mooring, or other marine property. It generally does not cover hull damage, motor damage, or your own equipment. This is often the minimum level marinas require before allocating a berth or mooring.
Typically covers
- Damage to other vessels
- Damage to moorings, jetties, and marine property
- Third-party liability cover
Best suited for
Older dinghies, small runabouts, or lower-value vessels where the cost of full hull cover exceeds what the boat is worth. Also suits boat owners who want marina access at the lowest premium.
Third Party, Fire and Theft
Generally includes everything in Third Party only, plus cover if your vessel, outboard motor, or inboard engine is stolen or damaged by fire. It typically does not pay for accidental hull damage from collisions, grounding, sinking, or storm events.
Typically covers
- All third-party liability cover
- Theft of your vessel, motor, or equipment
- Fire damage to your vessel
- Attempted theft damage
Best suited for
Mid-value boats where theft is a real concern, particularly trailer boats stored at home or in unsecured areas. A middle ground for owners who want more than liability alone.
Comprehensive (full hull)
The highest level of boat insurance available. Full hull insurance typically protects against accidental damage, collision, grounding, sinking, storm damage, theft, fire, and transit damage while the boat is on a trailer. Cover generally extends to the hull, gel coat, propeller, rudder, and permanently fitted equipment. If the vessel is a total loss, you may receive either the agreed value or market value payout depending on your policy terms.
Typically covers
- All Third Party and fire/theft cover
- Accidental damage (collision, grounding, sinking)
- Storm and weather damage
- Transit damage (on trailer)
- Salvage and wreck removal
- Motor and outboard cover
- Electronics and navigation equipment
Best suited for
Any vessel with meaningful replacement value. Particularly recommended for financed boats (most marine lenders require it), newer launches, yachts, keelboats, catamarans, and trailer boats used regularly on open water. The most popular choice among boat owners from Auckland to Dunedin.

What does boat insurance cover?
This table shows what is typically included at each level. Exact inclusions vary between insurers and policy wordings, which is why it pays to have a broker review the fine print.
| Cover feature | Third Party only | Fire and theft | Comprehensive |
|---|---|---|---|
| Third-party liability | Yes | Yes | Yes |
| Theft | No | Yes | Yes |
| Fire | No | Yes | Yes |
| Storm and weather damage | No | No | Yes |
| Hull damage (collision, impact) | No | No | Yes |
| Sinking and grounding | No | No | Yes |
| Transit damage (on trailer) | No | No | Yes |
| Motor and engine damage | No | Theft/fire only | Yes |
| Trailer cover | No | Optional | Optional |
| Salvage and wreck removal | No | No | Yes |
| Propeller and rudder | No | No | Yes |
| Personal effects and fishing gear | No | No | Optional |
| Navigation equipment | No | Theft/fire only | Yes |
| Tender or dinghy | No | No | Optional |
| Racing and regattas | No | No | Optional |
Trailer cover is often treated as a separate add-on regardless of policy level. If your boat lives on a trailer, make sure trailer damage and theft are explicitly included. Personal effects (fishing gear, wetsuits, electronics), tender or dinghy cover, and racing or regatta endorsements are typically optional and need to be requested. Navigation equipment such as GPS plotters and fishfinders may have a separate sub-limit within the sum insured.
Agreed value vs market value for boats
This choice determines how much you receive if the vessel is a total loss, whether from sinking, storm damage, fire, or theft. Boats depreciate quickly, so the gap between what you paid and what the market says it is worth can be significant within a few years.
Agreed value
You and the insurer agree on a fixed sum when the policy starts. If the vessel is a total loss, you receive that amount less your excess, regardless of how much the boat has depreciated since purchase.
Advantages
- Certainty: you know exactly what you will receive
- Protects against steep boat depreciation
- No disputes about valuation at claim time
Considerations
- - Typically a slightly higher premium
- - The agreed amount needs to be reviewed at each renewal
Market value
The insurer pays what the vessel is worth on the open market at claim time, based on age, condition, hours on the motor, and comparable sales. The payout may be considerably less than what you paid, especially for boats under five years old.
Advantages
- Generally lower premium
- No need to set a value upfront
- Suitable for older vessels where depreciation has already occurred
Considerations
- - Payout decreases each year as the vessel depreciates
- - Potential for disputes over the assessed market value
- - You may receive far less than what you still owe on marine finance
Boats lose value faster than cars. A vessel can depreciate significantly within the first few years on the open market. Agreed value is generally recommended for newer boats and any vessel with marine finance owing. At each renewal, we review the agreed amount to make sure it still reflects what it would actually cost to replace the vessel with a comparable one.
Factors that affect your boat insurance premium
Premiums are calculated on a range of risk factors specific to marine insurance. Knowing what drives the price helps you make informed decisions about your vessel and how you store it.
Vessel type and size
A 4-metre aluminium dinghy costs far less to insure than a 12-metre yacht. Vessel length, construction material (fibreglass, aluminium, timber, inflatable), and overall design all factor into the premium. Larger vessels cost more to repair and salvage.
Age and condition
Older vessels may attract higher premiums or require a marine survey before cover is offered. Well-maintained boats with current survey certificates, regular haul-out records, and documented service history are viewed more favourably by insurers. Fibreglass and aluminium hulls age differently, and insurers factor hull material into the risk assessment.
Engine type and power
Outboard motors, inboard engines, and jet drives each carry different risk profiles. Higher horsepower means higher speed capability and greater repair costs. The motor is often the most expensive single component to replace on a trailer boat.
Storage and mooring location
A vessel stored in a locked compound or secure marina attracts lower premiums than one on an open trailer at home. Location matters too. Cruising grounds like the Hauraki Gulf, Bay of Islands, and Marlborough Sounds each carry different exposure to storm and surge risk. Haul-out and hardstand storage during winter can reduce your premium, and keeping up with annual antifoul and maintenance signals lower risk to insurers.
Usage: recreational vs commercial
Recreational use (fishing, cruising, water sports) is rated differently to commercial use (charter, fishing tours, dive operations). Commercial use means more time on the water, more passengers, and a higher risk profile. Make sure the policy matches how you actually use the vessel.
Skipper experience and claims history
Boating qualifications, years of experience, and a clean claims history all work in your favour. Previous claims, particularly for grounding or collision, increase the premium. Holding a recognised skipper qualification (such as a Coastguard Day Skipper certificate) can help.
Other insurance you might need
Many of our clients who own boats also need cover for a vehicle, a trailer, a home, or the contents inside it. We review everything in one conversation so nothing gets missed and you benefit from having all policies managed by one broker.

Common boat insurance questions
These are the questions boat owners ask most often, whether you are berthed in Auckland's Hauraki Gulf, cruising the Bay of Islands, or launching from a Tauranga boat ramp. If your question is not here, request a callback and we will be in touch.
Do I need boat insurance in New Zealand?
There is no legal requirement to insure a boat. The Maritime Transport Act covers safety standards, not insurance obligations. However, most marinas and mooring facilities require proof of third-party liability cover before they will let you berth. Auckland marinas, Tauranga's Bridge Marina, and facilities throughout Marlborough Sounds all ask for it. If you damage another vessel, a jetty, or marine infrastructure without insurance, you are personally liable for the full cost. Salvage and wreck removal alone can run into tens of thousands of dollars, whether you own a trailer boat, a yacht, or a pontoon.
What is the difference between hull insurance and marine liability?
Hull insurance covers physical damage to your vessel, outboard motor or inboard engine, propeller, rudder, and permanently attached equipment. Marine liability covers your legal responsibility if your boat damages someone else's property or injures a third party. Most comprehensive policies bundle both, but third-party-only policies cover liability without protecting your own vessel.
Does my boat insurance cover the trailer?
Some boat policies include the trailer as standard, while others treat it as an optional add-on or exclude it entirely. Trailer cover typically protects against theft, fire, and accidental damage while the trailer is attached to your vehicle or stored at home. Check the policy wording carefully, because a missing trailer can leave you stranded at the boat ramp.
Are jet skis and personal watercraft (PWC) covered under boat insurance?
Jet skis and PWC usually need a separate policy or a specific endorsement on your marine insurance. Standard boat policies for launches, powerboats, and yachts often exclude PWC because they carry a different risk profile. If you own both a boat and a jet ski, we can arrange cover for both under one review.
Does my insurance cover me in international waters?
Most recreational boat policies cover coastal waters and inland waterways as standard. Popular cruising grounds like Auckland's Hauraki Gulf, Bay of Islands, Marlborough Sounds, and Wellington harbour fall within the standard navigation area. Voyages to the Pacific Islands or beyond typically require an extended cruising range endorsement. If you plan to sail offshore, let us know before you leave so we can confirm cover is in place.
What factors affect my boat insurance premium?
The main factors are vessel type and length, engine type and horsepower, age and condition, how and where it is stored, your boating experience, claims history, and whether you use it for recreation or commercial purposes. The sum insured and your chosen excess also affect the price. Opting for a higher voluntary excess lowers the premium but increases what you pay out of pocket on a claim. A well-maintained vessel stored in a secure marina or locked compound generally attracts a lower premium than one kept on an open trailer.
Does my home contents policy cover my boat?
Home contents policies sometimes cover small watercraft like dinghies or kayaks up to a specified value, but larger boats such as trailer boats, launches, and powerboats are almost always excluded. Outboard motors and trailers are typically excluded too. If you assume your contents policy covers the boat and it does not, you will find out at the worst possible time. A standalone marine policy is the reliable option.
How do I make a claim on my boat insurance?
You contact the insurer directly to lodge the claim. They will ask for details of the incident, photos of the damage, and any relevant maritime or police reports. For salvage situations, contact the insurer as soon as possible because delays can increase costs. Kapi Insurance arranges the policy but does not handle claims. You deal with the insurer for that.
Can I get insurance for racing or fishing tournaments?
Racing, regattas, and tournament cover is available but not included in standard recreational policies. If you race a keelboat or yacht competitively, or enter organised fishing tournaments, you need to disclose this when arranging cover. Failing to mention it could void the policy. We can source cover that includes racing and regattas, but the premium will reflect the additional risk.
What is the difference between agreed value and market value for boats?
Agreed value locks in a set sum insured when the policy starts. If the vessel is a total loss, you receive that amount less your excess. Market value pays what the boat is worth at the time of the claim based on age, condition, hull material (fibreglass, aluminium, or timber), and comparable sales. Boats depreciate quickly, so agreed value is strongly recommended for newer vessels, whether you own a catamaran, keelboat, or trailer boat, to avoid a shortfall.
