2026 NZ Car Insurance: Comprehensive Too Pricey? Why Third Party, Fire & Theft is the Best Bet for Older Cars

By InsurspyPublished 2 February 2026

Introduction

For an older or lower-value vehicle, Third Party, Fire & Theft (TPFT) can be a sensible middle ground—but it is not automatically the best choice. It protects you against liability for damage you cause to other people’s vehicles or property, and adds cover for fire and theft of your own vehicle. It generally does not pay to repair your own vehicle after an at-fault collision.

As at 17 August 2026, the right decision is less about a fixed vehicle-value threshold and more about the gap between matched quotes, your excess, how the vehicle would be settled after a loss, and whether you could afford to replace or repair it yourself. For a broader starting point, see our New Zealand car insurance guide.

In our editorial review, TPFT is most worth considering where comprehensive cover feels disproportionate to the protection needed, while theft and fire remain risks the owner does not want to self-fund.

Comprehensive, TPFT and Third Party: the practical difference

Cover type	What it generally protects	Key trade-off for an older vehicle
Third Party Only	Damage you cause to another person’s vehicle or property.	Your own vehicle is not covered for fire, theft or most collision damage.
Third Party, Fire & Theft	Third-party liability, plus fire and theft cover for your vehicle, subject to the policy.	You normally carry the cost of damage to your own vehicle when you cause the crash.
Comprehensive	Third-party liability plus accidental damage to your own vehicle, as well as other insured events under the policy.	Usually provides broader protection, but the quote and excess may make it less attractive for some vehicles.

These are general cover categories. The schedule, wording, exclusions, excess and optional benefits determine what a particular policy actually pays.

When TPFT may be worth considering

TPFT may suit an owner who wants protection from the potentially large cost of damaging someone else’s property and does not want to bear a theft or fire loss alone, but is prepared to self-fund their own at-fault collision damage.

It may be less suitable if you rely heavily on the vehicle and could not readily repair or replace it after an at-fault crash. Finance obligations may also require a particular level of cover; check the finance agreement rather than assuming TPFT is permitted.

Price pressure is a valid reason to compare cover, but not a reason to compare unlike-for-like policies. Consumer NZ reported that, in its survey, third-party-only policies were typically five to six times cheaper than Comprehensive cover. That does not mean TPFT will be right for every driver: quote prices vary with the driver, vehicle, driving history and location. Consumer NZ also found material differences between insurers’ quotes in its survey, reinforcing the value of obtaining comparable quotes.

Important TPFT limits to check before switching

Own collision damage

This is the central trade-off. If you hit another vehicle, fence or other property, third-party liability cover is intended to deal with the damage you caused. But TPFT usually will not pay to repair your car from that at-fault collision. Do not treat TPFT as “full cover”.

Theft, fire and attempted theft

Check the wording rather than relying on the product name. For example, AMI’s current TPFT wording covers sudden and accidental loss caused by fire, theft and attempted theft, subject to its terms. Benefits such as glass, towing, hire transport, roadside assistance and personal items can differ materially between policies or may be optional.

Uninsured-motorist protection

Many New Zealand motor policies include an uninsured-motorist extension, sometimes called innocent-party protection, but it is not universal and limits and conditions differ. It is not a substitute for comprehensive cover.

As a specific current example, AMI’s TPFT uninsured-motorist-damage benefit has a maximum of $5,000 in total, including towing and storage. It requires the other uninsured driver to be completely at fault, correct registration and contact details, and reasonable help with recovery. It has no excess under that benefit. Check the wording and schedule for the insurer you are considering; do not assume another TPFT policy uses the same limit or fault test.

Market value or agreed value

Settlement basis can matter as much as the premium. Market value is the vehicle’s value immediately before the loss. Agreed value is set with the insurer, but should still be reviewed at renewal. Second-hand vehicle values can change and an insurer may change an agreed value at renewal. Keep useful evidence of your vehicle’s condition and value, and confirm the basis shown on your schedule.

Excesses and eligibility

Compare the standard excess and any additional excesses that may apply. Also check listed-driver rules, permitted use, licence conditions and disclosure obligations. Official consumer guidance notes that claims may be questioned or refused where, for example, a vehicle is unsafe, alcohol or drugs are involved, licence conditions are breached, an unnamed driver uses a named-driver policy, or private-car use falls outside policy conditions.

A quote-comparison checklist

Request comparable quotes for Comprehensive, TPFT and Third Party Only using the same driver details and excess where possible.
Confirm what you would receive if the vehicle were stolen or destroyed: market value or agreed value.
Read the fire, theft and attempted-theft wording, including exclusions and excesses.
Ask whether uninsured-motorist protection applies, its maximum payment, the fault test, required driver details and any excess.
Check whether glass, towing, temporary transport, roadside assistance and personal belongings are included, optional or excluded.
Consider the loss you would need to absorb after causing a crash. Could you repair or replace the vehicle without insurance paying for that damage?
At renewal, review vehicle value, drivers, vehicle use, address and any other material changes before accepting the offer.

Keep the vehicle roadworthy and the information accurate

A current WoF is a periodic safety inspection, not a guarantee that a vehicle remains safe between inspections. NZ Transport Agency Waka Kotahi says owners must keep their vehicles in WoF condition at all times. Keep the vehicle roadworthy, comply with licence conditions and tell the insurer about relevant changes. An expired document is not, by itself, a universal automatic claim refusal; the issue is whether safety, legality and policy conditions affect the claim.

Practical Takeaway

TPFT can be a balanced option for an older vehicle when you want third-party liability protection plus fire and theft cover, while knowingly accepting most at-fault damage to your own car. It is not a universal downgrade rule based on a vehicle’s age or price.

Before changing cover, compare matched current quotes and read the policy wording that applies to your quote. Focus on the settlement basis, excess, uninsured-driver terms and the amount you could afford to lose. This article is general information, not personalised insurance or financial advice.
