Car Insurance

Car insurance policies typically cover damage to your vehicle from accidents, theft, fire, weather events, and vandalism. Comprehensive policies provide the broadest protection, covering both damage to your own vehicle and liability for damage to others' property and vehicles. Third party policies cover damage you cause to other people's property and vehicles, while third party fire and theft adds protection for your own vehicle in those specific circumstances.

Coverage levels vary by policy type, with options for agreed value or market value settlements, windscreen cover, rental car reimbursement, and roadside assistance. Modern policies must account for increasingly expensive repairs due to advanced vehicle technology including sensors, cameras, and driver-assist systems, a simple bumper replacement on a newer vehicle can now cost $3,000–$5,000 when sensors need recalibration.

It's essential to ensure your sum insured reflects current replacement costs, not outdated values from when you first purchased the policy. Most comprehensive policies also include liability cover up to $20 million for injury or property damage you cause to others, legal liability protection, and cover for personal belongings damaged in an accident. Optional extras like hire car cover, excess-free windscreen replacement, and specified accessories cover can be added to match your specific needs.

Your car insurance premium is calculated based on several key factors:

• Driving history — A clean record with no claims can reduce your premium significantly, while recent at-fault accidents can increase premiums by 20–40%

• Vehicle type and value — High-performance vehicles can cost 25–40% more to insure than comparable standard vehicles. Vehicles with advanced safety features may qualify for discounts, while those with high theft rates or expensive parts cost more

• Location — Urban drivers generally pay 10–15% more than rural drivers due to higher exposure to theft, vandalism, and traffic incidents. Auckland and Wellington typically have the highest premiums

• Annual kilometres driven — High-mileage drivers (20,000km/year) typically pay more than occasional drivers (5,000km/year) due to increased accident exposure

• Driver age and experience — Drivers aged 16–24 face significantly higher premiums as they account for roughly 25% of all fatal and serious injury crashes. Premiums typically decrease after age 25 and stabilise between 30–65

• Excess level — Increasing your excess from $400 to $800 can reduce annual premiums by 5–10%, while pushing it to $1,000 might save 10–15%. However, higher excess only makes sense if you can comfortably cover that amount in an emergency

• Security features — Vehicles with immobilisers, alarms, and tracking devices may qualify for premium discounts of 5–10%

Car Insurance in New Zealand: What You Need to Know

Car insurance is one of the most commonly purchased insurance products in New Zealand — and one of the most commonly misunderstood. Most drivers know they need it, but far fewer understand exactly what their policy covers, what it excludes, and whether the sum insured still reflects the real cost of replacing their vehicle. By the time those questions matter, it's usually because something has gone wrong.

This guide explains how car insurance works in New Zealand, what your policy should include, the factors that affect your premium, and how working with an independent broker like Gerrards helps you get cover that's actually fit for purpose.

The Three Main Types of Car Insurance

New Zealand car insurance is typically available in three tiers. Each offers a different level of protection, and the right choice depends on your vehicle's value, how much you drive, and your financial situation.

• Comprehensive car insurance — The highest level of cover. It protects your own vehicle from accidental damage, theft, fire, weather events, and vandalism, and covers damage or injury you cause to other people and their property. Most drivers with a vehicle worth more than $10,000 benefit most from comprehensive cover.
• Third party fire and theft — Covers you for damage you cause to other vehicles and property, and adds protection if your own car is stolen or damaged by fire. A middle-ground option often suited to vehicles of moderate value.
• Third party only — The most basic form of cover. It protects you against claims made by others if you damage their property or vehicle, but offers no protection for your own car. This may suit older, low-value vehicles where comprehensive cover isn't cost-effective.

Note that New Zealand does not require compulsory third party insurance by law, unlike some other countries. ACC covers personal injury on the road, but there is no legal requirement to hold vehicle liability insurance — making it all the more important to choose cover that matches your risk exposure.

What a Good Comprehensive Policy Should Include

Not all comprehensive policies are created equal. When reviewing your options, look for the following features as standard or available as add-ons:

• Agreed value vs. market value — Agreed value policies pay out a fixed amount you and the insurer agree on at the start of the policy. Market value policies pay what the vehicle is worth at the time of the claim, which may be less than you expect. For most drivers, agreed value offers more certainty.
• Liability cover — Most comprehensive policies include third party liability up to $20 million for property damage or injury you cause. This is critical protection if you're involved in a serious incident.
• Windscreen and glass cover — Chips and cracks are among the most common car insurance claims. Many policies include excess-free windscreen cover, or it can be added for a small extra premium.
• Rental car cover — If your vehicle is off the road following a claim, hire car cover means you're not left without transport. Some policies include a set number of days; others allow you to specify the benefit level.
• Roadside assistance — Breakdown assistance, towing, and emergency fuel delivery. Often bundled with comprehensive policies or available as an add-on.
• New vehicle replacement — Some policies will replace your vehicle with a new one if it's written off or stolen within the first year or two of ownership.
• Uninsured driver protection — If you're hit by a driver with no insurance, this covers your excess or repairs, so you're not out of pocket through no fault of your own.
• Personal belongings — Covers items damaged or stolen from your vehicle, such as laptops, sports equipment, or child safety seats, up to a specified limit.

The Hidden Risk: Underinsurance

Underinsurance is one of the most significant and preventable problems in car insurance. Around 40% of New Zealand policyholders are underinsured, meaning they would not receive enough from a claim to cover their actual loss. This commonly happens in three ways:

• Outdated agreed values — You set your vehicle's agreed value several years ago and haven't reviewed it. Used car values have risen sharply in recent years; if your agreed value doesn't reflect the current replacement cost, you'd face a shortfall at claim time.
• Overlooked exclusions — Every policy has exclusions. Common ones include wear and tear, mechanical breakdown, using the vehicle for business purposes when only personal use is declared, and driving under the influence. Many policyholders aren't aware of these until a claim is declined.
• Wrong excess level — A high excess can make a policy look affordable but may leave you unable to afford a claim when the time comes. Conversely, a low excess on a low-value vehicle may not be cost-effective.

The right time to address these gaps is before you need to make a claim, not after. An annual policy review — something Gerrards provides as a standard part of the service — ensures your cover keeps pace with your circumstances.

Modern Vehicles and Rising Repair Costs

If your current policy was set up more than two or three years ago, it's worth revisiting the coverage limits in light of how much repair costs have changed. Modern vehicles are substantially more expensive to repair than their predecessors, even in minor accidents. Here's why:

• Advanced driver assistance systems (ADAS) — including lane-keep assist, automatic emergency braking, and parking sensors — are typically embedded in bumpers, windscreens, and mirrors. Replacing any of these components requires sensor recalibration, which can add $500–$2,000 to a repair bill.
• Modern paint systems, lightweight alloy panels, and bonded construction methods are more expensive to repair correctly than older body-on-frame designs.
• Parts supply constraints and the cost of genuine OEM parts have pushed average claim values up roughly 7% annually over the past five years.

A minor rear-end collision that cost $2,000 to fix five years ago can now easily exceed $5,000 — and that's with a vehicle that isn't considered luxury or high-performance. Making sure your agreed value and coverage limits reflect these realities is not optional; it's essential.

What Affects Your Car Insurance Premium?

Car insurance premiums in New Zealand are calculated using a range of risk factors. Understanding these helps you make informed decisions about your coverage and excess levels:

• Your driving history — A clean driving record typically results in lower premiums, while at-fault accidents can increase premiums by 20–40% at renewal.
• Vehicle make, model, and value — High-performance, luxury, and imported vehicles cost more to insure. Vehicles with high theft rates or expensive parts also attract higher premiums.
• Where you live and park — Drivers in Auckland and Wellington typically pay 10–15% more than rural drivers due to higher exposure to accidents, theft, and vandalism. Garaging your vehicle overnight can reduce your premium.
• How much you drive — Annual kilometres driven directly affects your exposure to risk. Low-mileage drivers often qualify for reduced premiums.
• Your age and experience — Drivers aged 16–24 pay significantly higher premiums, as young drivers are involved in a disproportionate share of serious crashes. Premiums generally decrease after 25 and stabilise through mid-life.
• Your excess — Increasing your excess reduces your premium, but only makes sense if you can comfortably cover that amount in an emergency. A higher excess is not a saving if it prevents you from making legitimate claims.
• Security features — Immobilisers, approved alarms, and GPS tracking devices can attract premium discounts of 5–10% with some insurers.

Why Work With an Independent Broker?

When you go directly to an insurer, you're choosing from one company's product range. When you work with Gerrards, you're accessing policies from 20+ insurers — and an adviser who is working for you, not for the insurer.

The difference matters most when it counts: at claim time. If your insurer disputes a claim, offers a settlement lower than your expectations, or declines cover based on an exclusion you weren't clearly informed about, having a broker in your corner changes the outcome. Gerrards advocates for clients throughout the claims process — pushing back on low settlements, managing paperwork, and escalating disputes where necessary.

Independent brokers also have access to products and pricing that isn't available through direct or comparison website channels. Some insurers work exclusively through brokers; others offer better terms through the broker channel than direct. This means the advice you receive isn't just about what's available publicly — it's about what's genuinely the best fit for your situation across the full market.

Car Insurance for Different Driver Profiles

The right car insurance policy varies significantly depending on who you are and how you use your vehicle. Here are some common scenarios where the right coverage can make a significant difference:

• Young and first-time drivers — Premiums are highest for this group, but that doesn't mean all options are equivalent. Some insurers take a more favourable view of young drivers who have completed advanced driver training or who are named on a parent's policy. Excess structures for young drivers also vary significantly between insurers.
• High-value vehicle owners — Agreed value policies are especially important here, as market value settlements on prestige vehicles can be unpredictable. Specialist insurers often provide better coverage terms for high-value vehicles than mainstream providers.
• Business use — If you use your personal vehicle for work purposes — visiting clients, attending off-site meetings, or transporting equipment — you need to declare this. Many standard personal car policies exclude business use, meaning a claim arising from a work-related trip could be declined.
• Rural and lifestyle property drivers — Off-road driving, gravel roads, farm access tracks, and driving livestock carriers alongside passenger vehicles creates a different risk profile. Standard urban policies may not adequately reflect this.
• Older vehicles — As vehicle value decreases, comprehensive cover may no longer represent good value. Third party fire and theft, or third party only, may make more financial sense once a vehicle's value falls below a certain threshold. A broker can help you work through this calculation.

Getting the Most From Your Policy

Once you have cover in place, there are several things you can do to ensure you get full value from your policy:

• Review your agreed value annually — especially in a period where used car values are fluctuating.
• Notify your insurer or broker if you make significant modifications to your vehicle, as these can affect coverage.
• Keep your details accurate — changes in address, annual kilometres, or primary driver can all affect whether a claim will be paid.
• Understand your excess before you need to make a claim. Know what you'd owe in different scenarios, and make sure you can comfortably cover it.
• Contact your broker before deciding not to claim. Sometimes a small claim has premium implications that outweigh the payout; other times, the opposite is true. A broker can help you make the right call.
