Why Is Car Insurance So Expensive in New Zealand? The Real Reasons Behind Soaring Premiums

By InsurspyPublished 29 June 2025

Introduction

A costly car-insurance renewal does not necessarily mean every driver is seeing the same increase. In New Zealand, motor-insurance premiums are individually priced: the vehicle, driver and claims-related risks matter, while wider costs such as repairs, reinsurance, government levies and taxes can also affect pricing.

As at 17 August 2026, there is an important new cost component to understand. From 1 July 2026, the Fire and Emergency New Zealand (FENZ) levy for a motor vehicle insured under a motor-vehicle insurance contract is $25 a year, exclusive of GST. It is collected through insurance and is pro-rated for the period of cover. It is one part of a total premium, not a complete explanation for a particular renewal quote.

In our editorial review, the useful question is not simply “why is insurance expensive?” but “which parts of this quote reflect my cover, my risk details and costs that have changed?”

For a starting point when comparing options, see our car insurance information.

Why one driver’s premium can differ from another’s

There is no single national car-insurance price that applies to everyone. The Insurance Council of New Zealand (ICNZ) identifies the item being insured, claims history and claims costs, reinsurance rates, government levies and taxes as relevant inputs. For vehicle insurance, a motorist’s age, previous claims and the vehicle’s make and model may also affect the price.

Pricing influence	Why it can matter	What to check
Vehicle and expected claims cost	The make, model, value and expected cost to repair or replace a particular vehicle can affect the insurer’s assessment.	Ensure the vehicle details and declared use are correct; seek a vehicle-specific quote rather than relying on assumptions about a type of car.
Driver details and claims record	Age and previous claims can be relevant. Consumer Protection notes that drivers under 25 and people without a full licence can pay higher premiums.	Check that all regular drivers, licences and claims information are accurately disclosed.
Repair, labour, materials and technology	These costs can influence the expected cost of claims.	Ask the insurer which quote details can be changed without reducing cover you need.
Reinsurance and natural-hazard losses	Insurers may use reinsurance to manage large-loss exposure, and reinsurance costs can be reflected in pricing.	Do not assume a renewal change has one cause; ask for an explanation of the premium change.
Government levies and taxes	They can form part of the total amount charged through an insurance policy.	Distinguish them from insurer pricing and from separate vehicle-licensing charges.

Premium conditions do not move in one direction for every insurer or customer. In February 2026, Suncorp New Zealand reported easing vehicle-parts inflation and more stable global reinsurance conditions, and said many of its policyholders had recently experienced lower increases or reduced premiums. That is insurer-specific information, not a nationwide average or a promise about another insurer’s quote.

The FENZ levy and ACC charges are different

It is easy to group all vehicle-related charges together, but they are not the same.

FENZ levy: From 1 July 2026, the annual levy for a motor vehicle insured under a motor-vehicle insurance contract is $25, exclusive of GST. The amount is pro-rated for the insurance period.
ACC motor-vehicle levies: These are separate accident-compensation charges associated with vehicle licensing and, for petrol vehicles, fuel. They are not part of a private car-insurance premium.

When reviewing a renewal, ask the insurer how the quoted total is presented and which changes relate to cover, rating factors or levies. Avoid assuming that a levy change alone explains the full movement in your price.

Cover level affects the price—and the risk you retain

A lower premium can mean you are retaining more financial risk. Consumer Protection describes third-party cover as the least expensive main policy type. Third party, fire and theft also covers third-party liability plus theft and fire. Comprehensive cover is generally more expensive and offers the widest range of cover, including damage to the insured vehicle.

Cover type	General scope	Key decision question
Third party	Generally the least expensive main type of cover.	Could you afford to repair or replace your own vehicle after damage or loss?
Third party, fire and theft	Adds theft and fire cover alongside third-party liability.	Does this better match the value and risks of your vehicle than third party alone?
Comprehensive	Generally costs more and includes damage to the insured vehicle, subject to the policy wording.	Which exclusions, limits, excesses and optional benefits apply to the specific policy?

Do not presume that roadside assistance, glass cover, a replacement vehicle, towing, rental-car cover or excess relief is included. Benefits, exclusions, sub-limits and eligibility differ between products. Read the current policy wording and schedule before deciding that two quotes are equivalent.

Ways to review costs without chasing a false saving

Compare like with like. Check the cover type, sum or basis of cover where applicable, excess, named drivers, exclusions and optional benefits—not just the headline price.
Consider the excess carefully. A higher excess can reduce a premium, but Consumer Protection advises choosing an excess you could afford if you need to claim.
Confirm your information. Update the vehicle’s garaging address, use, drivers and licence details where relevant. Incorrect or incomplete information can undermine a meaningful comparison.
Ask about relevant security and storage details. Tell the insurer if the vehicle is kept in a locked garage or has an alarm. These details may be relevant to the premium, but they do not guarantee a discount.
Check discounts rather than assuming them. Ask whether a multi-policy discount may be available if you also hold house or contents cover with the insurer, and whether a multi-vehicle discount applies. In 2026, the FMA warned an insurer over failures to apply advertised multi-policy and/or multi-vehicle discounts, resulting in overcharges.
Ask direct renewal questions. The FMA suggests asking how the premium is calculated, whether discounts are included, whether the product remains suitable and what changes are available.

Practical Takeaway

Expensive car insurance in 2026 is usually the result of a combination of personal risk details, the vehicle, expected claims costs, reinsurance and levies—not one universal market price or one single cause. The new FENZ levy is relevant to insured vehicles from 1 July 2026, but it should be considered alongside the full quote.

Before accepting a renewal, obtain comparable quotes, read the current policy wording, and ask the insurer to explain material changes. A cheaper policy is not automatically better if it leaves you with an excess or exclusions you could not manage after a claim.
