Comprehensive Car Insurance NZ: Cover, Costs & What to Compare

Comprehensive is the widest car insurance most NZ drivers can buy for a private car, and the easiest to misunderstand. The word sounds like everything is covered. It is not. A policy pays for a long list of sudden, accidental events, then stops firmly at wear, breakdown and undisclosed business use. This guide covers what it pays for, agreed versus market value, excesses, add-ons, and when it stops making sense on an older car.

Quick answer

Comprehensive covers accidental damage to your own car, whether the crash was your fault or someone else’s, plus damage you cause to another person’s car or property. New Zealand policies typically also include theft and attempted theft, fire, storm and flood damage, vandalism and windscreen or window glass, plus towing after a covered event.

Cover is on an agreed value or market value basis. That choice decides what you get if the car is written off. You pay an excess on most claims, and extra excesses can apply, for example for a young driver. Comprehensive does not cover wear and tear, mechanical or electrical breakdown, or using a private car for business unless that use is declared and covered.

Car insurance is not compulsory in New Zealand. ACC covers personal injury through levies, not damage to cars or property, so an uninsured driver remains personally liable for property damage they cause.

Where comprehensive sits

The Insurance Council of New Zealand describes three main motor policy types. Third party property damage covers damage you cause to someone else’s vehicle or property. Third party, fire and theft adds fire and theft cover for your own car. Comprehensive adds accidental loss or damage to your own vehicle on top, with further benefits bundled around it.

Our overview at Car Insurance NZ compares the levels side by side. This page assumes you are already weighing up the top level, because two comprehensive policies can look similar on a quote screen and differ a lot in the wording. Consumer Protection notes comprehensive is generally the more expensive option, because it pays out in the widest range of situations. What matters is the value basis, the excesses, the glass terms, what happens while your car is off the road, and the exclusions.

What comprehensive usually covers

Examples come from insurers’ own pages and documents. Wording differs, so check your own policy.

Your own car, and other people’s property

Damage to your own car in a crash is the core benefit, and the one third party policies do not give you. Tower puts it plainly: if you have an accident and want your own car repaired, comprehensive is the only one of its cover levels that does that. Cover is for sudden and accidental loss or damage.

Comprehensive also includes legal liability for damage your car causes to another person’s vehicle or property. AMI lists cover for damaging someone else’s car or property up to $20 million, with a separate limit for injuries you cause. AA’s wording also sets a total liability limit per event, so read your own schedule. This cover is mainly about property damage. It is not a substitute for ACC, and AA’s wording excludes money that could be recovered from ACC.

Theft, fire, weather and vandalism

Theft, damage during attempted theft and fire sit inside comprehensive, as they do in third party, fire and theft. AMI lists theft, fire and accidental flood or storm damage among its comprehensive features. Tower lists fire, theft and natural disaster damage in the same way. AMI also lists vandalism separately. If the car is stolen and not found, or repair is uneconomic, the claim becomes a total loss and the value basis takes over. Some wordings, including AA’s, apply a short initial exclusion for natural disaster, fire, storm or flood on a new policy, with exceptions in the wording.

Glass, towing and uninsured drivers

Glass is covered, but payment terms vary. At Tower, windscreen and window glass are automatically covered, and an optional benefit removes the excess on glass claims. At AMI, excess-free glass is an optional extra. AA also offers it as an optional benefit, and its wording is narrower than people assume: sunroofs, glass roofs, mirrors and headlights are not part of AA’s optional glass benefit, and an excess can still apply if there is other damage at the same time. If bodywork around the glass must be fixed before glass can be fitted, excess-free treatment may not apply. AMI’s wording makes a similar distinction.

For towing, the Insurance Council notes comprehensive can include salvaging your vehicle and towing it to a repairer. Tower pays to remove an undriveable car to the nearest repairer or a place of safety after a covered loss. AA’s standard benefits include reasonable towing and storage, road clearing, emergency repairs and transport home when the car cannot be driven. Caps differ, so note yours if you travel long distances.

Comprehensive also covers your own damage when the other driver is uninsured. The Insurance Council adds that many policies include an uninsured motorist extension or innocent party protection. Where its conditions are met, typically that the uninsured driver can be identified and accepts involvement, the insurer may waive your excess and protect your no claims position. Tower requires identification details for not-at-fault claims and must be satisfied the other party was more than 50 percent at fault. Names, registration, insurer details and photos at the scene are what turn that promise into an actual waiver. Consumer Protection gives the same evidence advice.

Smaller bundled benefits

Examples verified include keys and locks (Tower lists up to $1,000, excess-free on a keys-only claim), child car seats (Tower lists up to $750), transport costs after an accident or theft (Tower lists up to $500), and a repair guarantee when you use the insurer’s network, described by Tower, AA and AMI on their own terms.

New vehicle replacement for a very new written-off car also varies: Tower describes replacement in the first two years from new, subject to availability, while AA’s cover in the wording checked applies where the car is less than one year old. Rely on the age limit in your wording, not the slogan. Treat these as tie-breakers.

Agreed value vs market value

If your car is written off, this choice sets the payout.

Market value is what the car was worth immediately before the loss. Consumer Protection defines it as what your vehicle is worth just before it is damaged, and the Insurance Council uses the same idea. IFSO explains that an insurer usually obtains pre-accident valuations for what the car would have sold for just before the loss, taking into account condition and modifications. A tidy car with service history values differently from the same model with worn tyres, dents and high kilometres. Market value tends to cost less in premium, because the insurer’s exposure falls as the car depreciates. The trade-off is uncertainty until a valuer assesses the car.

Agreed value is a figure you and the insurer agree at the start of the policy and at each renewal, as Consumer Protection and the Insurance Council both describe it. Tower defines it as the value agreed when you insure the car, at a change in cover or at renewal, shown on your certificate. Certainty is the attraction, which helps if you have finance owing. The settlement is based on that figure, less any applicable excess and any unpaid instalments the wording allows the insurer to deduct. Do not leave an old figure untouched while the car depreciates, and check any change at renewal. IFSO case experience includes a complaint where the agreed value had been reduced and the customer had not been clearly told.

AA’s wording checked here settles total loss on an agreed value basis. Other insurers let you choose. Want a known figure, have a loan to protect, or own an unusual spec? Look closely at agreed value. Prefer a lower premium, own a common model, and can live with a valuation at loss? Market value may suit. Either way, sense-check the figure against real asking prices for the same make, model, year, kilometres and condition. Our guide to valuing your car in NZ shows how.

A write-off does not mean a car that cannot be fixed. IFSO defines it in economic terms: repair costs more than the car is worth. Insurers also treat a car as a total loss where repair would be unsafe, or a stolen car has not been found within the period in the wording.

Excess: the part you pay

An excess is your contribution to a claim. Consumer Protection describes it as money you pay towards the damage when a claim is accepted. In most cases you pay it even if the accident was not your fault, IFSO warns, subject to limited exceptions.

Every policy has a standard excess on the schedule. Many insurers let you choose a higher voluntary excess for a lower premium. Consumer Protection makes the trade-off clear: a higher excess means you share more risk, so it can reduce what you pay, but think about how easily you could pay it if you claimed. Only choose a figure you could find at short notice.

Your schedule can list more than one excess, and AA’s wording warns you might have to pay more than one type for a single claim. The common extra is a young driver excess. Drivers under 25 are the usual trigger. The Insurance Council notes young drivers are statistically more likely to be involved in accidents and tend to face higher premiums, and Consumer Protection warns premiums are higher for drivers under 25 or without a full licence. Check whether the extra applies to any young driver, only to unnamed drivers, or only where the young person is not listed. Read the schedule as a stack: standard plus young driver excess is the total to hold in your head.

Policies often waive or reimburse the excess where another identified driver was at fault and wording conditions are met. AA lists criteria including the other driver’s correct name and contact details, the other vehicle’s correct registration, the responsible person confirming involvement, and the insurer agreeing your driver was not at fault. Theft is stricter. Do not assume a stolen car claim gets the excess back because you were blameless. IFSO case examples show wording can limit relief to particular accident circumstances, leaving the excess payable on theft. Report theft to police promptly.

Optional add-ons

Add-ons lift the premium, so each should earn its place.

Roadside assistance is help when the car will not go: flat battery, lockout or flat tyre. It is not towing after a crash, which comprehensive already covers after a covered event. Tower offers its RoadWise service as an optional benefit, covering the car rather than the person, with a set number of free call-outs per year. AMI includes Roadside Rescue with comprehensive at the time of checking, and offers it as an extra on lower levels.

Rental or hire car cover keeps you mobile while your car is repaired or a total loss is settled. Tower offers it up to $1,000 where the car is stolen or undriveable after an accident. AMI offers hire car or alternative transport for up to 21 days as an optional extra. AA offers rental cover after an accepted claim, with fuel, bond and extras left to you. Ask how many days, what class of car, and whether theft counts. A second car at home sharply reduces its value.

Excess-free glass suits drivers who do a lot of open road driving on chip-sealed roads. Compare its cost over a few years with one excess. Trailer and accessories cover is standard with a low limit in some wordings and optional in others. Tower lists both as optional. AA includes a domestic trailer benefit, excluding caravans and boat, horse or camper trailers.

Modifications need care. IFSO warns claims can be declined for non-disclosure, including undisclosed modifications. Tell the insurer when you modify the car.

What comprehensive does not cover

Wear and tear. AA excludes wear and tear, rust, corrosion, gradual deterioration and depreciation. A worn clutch and rust built up over years are ageing, not an insured accident.

Mechanical or electrical breakdown. AA states its policy does not cover failure of mechanical, electrical or electronic parts, nor damage resulting from fuel contamination or such a failure. Breakdown is sold separately as mechanical breakdown cover. If the engine fails with no accident involved, do not expect a comprehensive claim to pay for it.

Business use on a private policy. Tower states its private policies cover driving to and from work, but not using your car for work or business, and points business users to commercial cover. AA shows private use as private or domestic purposes only, and excludes carrying goods or samples for a trade or business and carrying fare-paying passengers. The Insurance Council adds that some private policies give automatic cover for occasional business use if there are no fare-paying passengers or goods deliveries, and recommends asking and extending the policy if needed. Delivering food, carrying stock, rideshare and courier work are not grey areas to test after a crash. IFSO records a claim declined because the owner had not told the insurer the vehicle was used for business.

Behaviour, licence and roadworthiness. AA excludes driving under the influence, failing to stop after an accident where it is an offence to do so, and licence non-compliance. IFSO warns learner and restricted breaches can leave the driver, or in some cases their parents, paying for damage to their own car and another’s. IFSO also warns claims can be declined if the car is unsafe or unroadworthy, even with a current warrant.

Other limits. Personal effects in the car are generally not part of the car itself under AA’s wording, and business goods are excluded there too. Consequential loss, such as lost income while the car is off the road, is excluded in AA’s wording unless a benefit you bought responds. Intentional and pre-existing damage and racing or track use also appear as exclusions. Read your own list in full.

What drives the premium

This site does not quote average premiums, and insurers do not publish a single price. Your premium reflects your car, drivers and history: the car’s value, model, repair costs and theft risk (Consumer Protection says the type of car plays a big part); driver age and experience, with under 25s and drivers without a full licence paying more; who drives it and whether use is commuting or business; address and garaging (tell your insurer about a locked garage or alarm); claims and licence history (Consumer Protection says a clean licence and not claiming make the biggest difference); and your choices on value, excess and add-ons. IFSO stresses answering insurer questions fully and accurately at application, renewal and claim time.

How to compare policies

Do not compare on premium alone. Consumer Protection says: do not just go on price, look at what each policy covers. Check the value basis and figure against current prices; your total excess, including any young, inexperienced or unnamed driver excess; glass terms; rental cover and days; the new car replacement window; repairer choice and guarantee; and whether scheduled use and exclusions match real life, including modifications and regular young drivers.

Making a claim

Lodge it promptly. AMI advises telling the insurer as soon as possible, and delay can complicate matters where memories fade, a second incident damages the same area, or rust sets in. AA requires reasonable steps to prevent further loss, a police report for theft, burglary or vandalism, and full details of the event and everyone involved.

Make the scene safe and check for injuries first. Exchange name, address, phone number, insurer, registration and licence details, and photograph damage and plates. Do not admit liability. AA’s conditions say you must not admit liability or negotiate, pay or settle without its consent. Notify your insurer, make the car available for assessment before repairs, and get permission before costs beyond urgent work to prevent further loss. The Insurance Council notes repair costs are checked before repairs are authorised. On a total loss, the settlement reflects the value basis, less the excess and any unpaid instalments the wording allows for. The policy typically ends then.

If a claim is declined and you disagree, Consumer Protection advises using the insurer’s complaints team first, then its dispute resolution scheme. IFSO handles many such complaints.

When comprehensive stops being worth it

No magic value makes comprehensive suddenly wrong. A hard dollar threshold, given without asking about your finances, is a guess. Ask four questions instead.

What is the car worth now, realistically, not what you paid? The lower that figure, the smaller the maximum payout for your own car, while liability cover continues on a cheaper policy either way.

What is the gap? Compare comprehensive with third party, fire and theft and with third party only for the same car and drivers. You pay that gap each year mainly to insure your own car’s value. If the gap over two or three years approaches a large share of the car’s worth, the maths gets hard to defend.

Could you absorb the loss? If the car was written off tomorrow for nothing, could you replace it or manage without it without debt stress? If yes, carrying the own-car risk yourself is rational. If the car is essential and replacement would mean a loan you do not want, comprehensive may still be worthwhile. Consumer Protection’s examples make the point: a driver with a $1,000 car chose third party because comprehensive cost almost as much as the car, while a driver whose car cost $12,000 chose comprehensive because repair or replacement would cost far more than the annual premium.

Does anyone require it? A finance agreement may require comprehensive for the loan term. Check before downgrading. Review the decision at each renewal, because cars depreciate and premiums move. Keep liability cover either way. The expensive accident is usually the one involving someone else’s car, and that risk does not shrink as your car ages.

Frequently asked questions

Is comprehensive the same as full cover?

Yes. Full car insurance is the common name for comprehensive cover, the term insurers use in policy names and wordings.

Is car insurance compulsory in New Zealand?

No, not for property damage. ACC, funded through levies including vehicle licensing, covers personal injury. It does not repair cars or fences, which is why at least third party cover is still widely recommended.

Does comprehensive cover a cracked windscreen?

Glass is covered for the insurers checked, but whether you pay an excess depends on the policy, on any excess-free glass benefit you hold, and on whether the claim is glass only.

Does comprehensive cover mechanical breakdown?

No, not as standard. Mechanical or electrical failure is excluded in the wordings checked and sold separately. Wear and tear is excluded too.

Can I use my privately insured car for work?

Commuting is treated differently from using the car in a business. Private policies checked do not cover business use such as carrying trade goods, deliveries or fare-paying passengers unless the policy is set up for it. Get the use shown correctly on the schedule.
