# How to choose comprehensive car insurance in New Zealand

When comparing comprehensive car insurance in NZ, **don't choose on price alone**. The biggest differences between policies are often the amount you'll receive if your car is written off, what happens if someone else damages your car, the excess you must pay, and the exclusions that could leave you out of pocket.

Here's what I'd compare before choosing a policy.

## 1. The most important things to compare

| What to compare | What to look for | Why it matters |
|---|---|---|
| **Premium** | Annual and monthly cost, including any instalment fees | A cheap policy may have a higher excess or less cover. |
| **Agreed value vs market value** | Whether your car is insured for an agreed amount or its market value at the time of a claim | This can make a substantial difference if your car is stolen or written off. |
| **Excess** | Standard excess and any additional excesses | A lower premium can come with a much higher out-of-pocket cost when you claim. |
| **Accidental damage** | Cover for collisions, reversing into objects, and accidental damage to your own car | Check the policy's specific terms and exclusions. |
| **Theft and attempted theft** | Whether theft, break-ins, and damage caused during attempted theft are covered | Particularly important if you park on the street or leave your car in public car parks. |
| **Storm, flood and other natural events** | Cover for flooding, hail, falling trees, and other weather-related damage | Natural-event cover and exclusions can differ between policies. |
| **Damage to other people's property** | The liability limit if you damage another vehicle or someone's property | Check that the limit is sufficient for a serious accident. |
| **Windscreen and window cover** | Whether glass claims are excess-free and whether there is an annual limit | Windscreen replacement can be expensive, especially for cars with cameras or driver-assistance systems. |
| **Repairs and parts** | Approved repairers, genuine parts, and any repair guarantees | Important for newer, imported, luxury, and electric vehicles. |
| **Rental car or alternative transport** | Whether a replacement vehicle is provided after an accident, theft, or both | Can help you avoid unexpected transport costs while your car is unavailable. |

**My recommendation:** Start by comparing the insured value, excess, and exclusions. These can matter much more than a small difference in annual premiums.

## 2. Agreed value vs market value: which is better?

This is one of the most important decisions when insuring your car in NZ.

- **Agreed value:** You and your insurer agree on an insured value for the policy period.
- **Market value:** Your insurer assesses what your car was worth immediately before the loss, according to the policy's valuation terms.

These values matter most if your car is written off or stolen and never recovered. The payout is subject to the policy terms and any applicable deductions. [Source: New Zealand Consumer Protection](https://www.consumerprotection.govt.nz/help-product-service/cars/paying-registering-insuring-car/car-insurance). 

### Example

Suppose you own a car worth $18,000.

| | Policy A | Policy B |
|---|---:|---:|
| Valuation basis | Agreed value | Market value |
| Example insured/payout valuation | $18,000 | $15,500 |
| Excess | $500 | $500 |
| Illustrative payout after excess | $17,500 | $15,000 |

These are illustrative figures, not actual insurer quotes.

**My recommendation:** If you want certainty about your car's insured value, look for an agreed-value policy. Check that the agreed amount reflects what your car is worth and review it at renewal.

Market-value cover can also be suitable, but check how the insurer determines market value and whether the sum insured limits its payout.

## 3. Compare the excess carefully

The excess is the amount you contribute towards an accepted claim.

For example, if repairs cost $4,000 and your applicable excess is $750, you would generally pay $750 and your insurer would cover the remaining $3,250.

However, some policies have additional excesses on top of the standard excess.

Check for:

- **Standard excess:** The amount you pay for an ordinary claim.
- **Young-driver excess:** An additional amount if a younger person is driving.
- **Inexperienced-driver excess:** An additional amount for drivers who have held their licence for a limited time.
- **Undisclosed-driver excess:** Potential additional costs if someone driving the car isn't covered under the policy terms.
- **Windscreen excess:** Whether glass claims have a separate excess or are excess-free.
- **Theft or other special excesses:** Whether particular types of claims attract additional charges.

Not every insurer applies all these excesses.

### Should you choose a higher excess?

A higher excess can reduce your premium, but you need to be comfortable paying it if you have an accident.

For example:

| | Lower-excess policy | Higher-excess policy |
|---|---:|---:|
| Annual premium | $1,500 | $1,300 |
| Excess | $400 | $900 |
| Annual premium saving | — | $200 |
| Extra cost if you claim | — | $500 |

In this example, the higher-excess policy saves $200 annually, but costs an additional $500 when you make a claim.

Compare the premium savings against the additional excess and how easily you could afford it. Consumer Protection NZ also recommends checking whether the excess is manageable before choosing a policy. [Read the official guidance](https://www.consumerprotection.govt.nz/help-product-service/cars/paying-registering-insuring-car/car-insurance).

## 4. Check the exclusions, not just the benefits

Two policies labelled comprehensive can have quite different exclusions.

Read the policy wording and check the following areas.

| Area | Questions to ask |
|---|---|
| **Who can drive?** | Are all household drivers covered? Are there age restrictions or additional excesses? |
| **Business use** | Is the car covered for commuting, work travel, deliveries or rideshare driving? |
| **Modifications** | Are aftermarket wheels, performance modifications, accessories and audio equipment covered? |
| **Driving overseas** | Does cover extend outside New Zealand, and if so, where? |
| **Mechanical failure** | Is damage from an accident covered while mechanical breakdown itself is excluded? |
| **Wear and tear** | Are rust, gradual deterioration, existing damage and worn components excluded? |
| **Unroadworthy vehicles** | Could a claim be declined if the car has an unsafe or illegal defect? |
| **Alcohol and drug impairment** | What restrictions apply when a driver is impaired? |
| **Keys and security** | What security precautions must you take, particularly after losing keys or if your car is stolen? |

Pay particular attention to **whether your actual use of the car matches the use declared on the policy**.

For example, if you use your car for paid deliveries but insure it only for private use, you could encounter problems with a claim.

You also need to disclose relevant information accurately and notify your insurer of material changes. Failure to do so can affect your cover. [Source: Consumer Protection NZ](https://www.consumerprotection.govt.nz/help-product-service/managing-money/insurance).

## 5. Compare the additional benefits

Optional benefits can make a meaningful difference, particularly if you rely on your car every day.

Here are the extras I'd look for.

| Benefit | Why it matters | What to check |
|---|---|---|
| **Windscreen and window cover** | Modern windscreens can be expensive to replace. | Whether replacement is excess-free and whether there are limits. |
| **Rental car after an accident** | Keeps you mobile while your car is repaired. | Maximum rental period and daily allowance. |
| **Rental car after theft** | Helps if your car is stolen and you're waiting for a settlement. | Whether theft is included and how long cover lasts. |
| **Towing and storage** | Covers some costs after an accident or breakdown. | Whether breakdown towing is included or requires an add-on. |
| **New-car replacement** | May provide a replacement vehicle rather than a cash settlement. | Vehicle age limits, eligibility requirements and availability in NZ. |
| **Personal belongings** | May cover certain items stolen from your car. | Dollar limits and exclusions; expensive items may need separate cover. |
| **Child car seats** | Can help replace seats damaged in an accident. | Whether replacement is covered and what conditions apply. |
| **Emergency accommodation or transport** | Useful after an accident far from home. | Eligible expenses and maximum benefits. |
| **Repair guarantee** | Offers reassurance about the quality of approved repairs. | Whether the guarantee lasts for as long as you own the car or for a specified period. |

Don't automatically pay extra for every benefit. Focus on the ones that would be expensive or difficult for you to go without.

For example, rental-car cover could be particularly valuable if you need your car to commute to work and have no alternative transport.

## 6. Check how the insurer handles repairs and write-offs

A good policy is about more than the payout. The claims process and repair arrangements matter, too.

I would compare:

- **Choice of repairer:** Can you choose your own mechanic or panel beater, or must you use the insurer's approved network?
- **Parts used:** Does the policy specify genuine manufacturer parts, or can alternative parts be used?
- **Repair guarantees:** What protection do you receive if repair work is faulty?
- **Write-off decisions:** How does the insurer decide whether a car is uneconomical or unsafe to repair?
- **Salvage:** What happens to the damaged car after a total-loss settlement?
- **Claims service:** How easy is it to lodge a claim, communicate with the insurer and track progress?
- **Repair delays:** What support is available if parts are difficult to source?

These points are especially important if you own an imported car, a luxury vehicle, a hybrid or an EV, where parts and repairs may be expensive.

I'd also look at customer satisfaction and complaints rather than relying solely on advertising or the insurer's headline rating.

Consumer NZ publishes a [car insurance buying guide and policy comparison](https://www.consumer.org.nz/money/insurance/car-insurance/guide), including research on premiums, policy features and insurers.

## 7. Check the cover suits your particular car

The best policy depends partly on what you drive.

### If you have a new or expensive car
Prioritise:
- An appropriate agreed value.
- New-car replacement cover, if available.
- Adequate protection for expensive repairs.
- Genuine parts and suitable repair arrangements.

### If you have an older car
Prioritise:
- An appropriate premium relative to the car's value.
- A manageable excess.
- A realistic insured value.
- Whether comprehensive cover is worth the cost compared with third-party alternatives.

For an older car, compare the annual premium and excess against the amount you could realistically receive if it were written off.

### If you have a hybrid or electric vehicle
Check:
- Whether the policy covers your particular vehicle and battery configuration.
- How battery damage is assessed after an accident.
- Repairer expertise and access to replacement parts.
- Towing arrangements if the vehicle cannot be driven.
- Whether charging cables and accessories are covered.

Don't assume every policy handles EVs or hybrids in exactly the same way.

### If other people drive your car
Check:
- Whether occasional drivers are covered.
- Whether you must list regular drivers.
- Any excess for drivers under 25.
- Any restrictions on learner or restricted licence holders.

If a partner, teenager or flatmate regularly drives your car, this can materially affect both the premium and the cover you need.

## 8. Which NZ insurers should you compare?

I'd start by obtaining quotes from at least three insurers, using exactly the same vehicle details, insured value, drivers and excess wherever possible.

Some options to investigate are:

- [AA Insurance](https://www.aainsurance.co.nz/)
- [AMI](https://www.ami.co.nz/)
- [State Insurance](https://www.state.co.nz/)
- [Tower](https://www.tower.co.nz/)
- [Cove](https://coveinsurance.co.nz/)
- [AMP](https://www.amp.co.nz/)

These are starting points, not a ranking of the best insurers. Eligibility, prices, excesses and policy features vary.

For a broader comparison, use:
- [Consumer NZ's car insurance comparison](https://www.consumer.org.nz/money/insurance/car-insurance) — independent buying guidance and policy research.
- [Canstar NZ's car insurance comparison](https://www.canstar.co.nz/car-insurance/) — a way to explore insurers and compare policy features.

**Important:** Quotes depend on factors such as your vehicle, age, driving history, location and claims history. An insurer that is cheapest for one driver might be expensive for another.

Also compare the total annual cost, including instalment fees if you pay monthly. Check the current policy wording rather than relying on a comparison website's summary.

## 9. My recommended comparison checklist

When you have three or four quotes, put them side by side using this checklist.

| Comparison item | Insurer A | Insurer B | Insurer C |
|---|---|---|---|
| Annual premium | | | |
| Insured value | | | |
| Agreed or market value | | | |
| Standard excess | | | |
| Additional driver excesses | | | |
| Windscreen excess | | | |
| Third-party property liability limit | | | |
| Rental car after an accident | | | |
| Rental car after theft | | | |
| Towing cover | | | |
| New-car replacement | | | |
| Choice of repairer | | | |
| Genuine parts provisions | | | |
| Key exclusions | | | |
| Customer service and claims reputation | | | |

The liability limit, repair provisions and optional benefits are worth comparing carefully because they can differ even when two premiums look similar.

### How I'd make the final decision

I'd use this order:

1. **Eliminate unsuitable policies.** Remove policies that don't adequately cover your vehicle, its use or the people who drive it.
2. **Compare insured values.** Make sure you're comparing like with like.
3. **Compare excesses.** Decide what you could comfortably afford to pay after an accident.
4. **Compare the policy wording.** Focus on exclusions and benefits that matter to you.
5. **Compare the annual premiums.** Once the cover is broadly equivalent, price becomes a more useful deciding factor.
6. **Check the claims experience.** Consider customer feedback and the insurer's claims service.

The cheapest comprehensive policy isn't necessarily the best value. I'd favour a competitively priced policy with an appropriate insured value, a manageable excess and clear claims provisions over one that saves a small amount but leaves important gaps in cover.

When choosing comprehensive car insurance in New Zealand, looking beyond just the price tag is crucial, as policies vary significantly in what they cover and how claims are handled. 

Key features and factors to compare include:

### 1. Valuation Type: Agreed vs. Market Value
* **Agreed Value:** You and the insurer agree on a set value for your car when you take out or renew the policy. If it's written off or stolen, you receive that exact amount (depreciating over time as cars age).
* **Market Value:** The insurer pays what your car was worth immediately before the incident, based on retail value. This usually results in a lower premium, but the payout might be lower than you expect.

### 2. Excess Structure (Standard and Additional)
* **Standard Excess:** The base amount you pay out-of-pocket when you make a claim. A higher excess generally lowers your annual premium, but make sure it’s an amount you can afford on short notice.
* **Additional/Special Excesses:** Check for extra penalties applied to younger drivers (e.g., under 25), learners/restricted license holders, or drivers with recent history/international licenses. Some insurers charge heavily for unnamed or young drivers, while others offer low fixed excesses.

### 3. Repairer Choice and Guarantees
* **Repairer Choice:** Some policies require you to use the insurer’s "preferred repairers" network, while others let you choose your own mechanic or repair shop. 
* **Repair Guarantee:** Check if the insurer guarantees the quality of the repairs for as long as you own the vehicle.

### 4. Standard Inclusions vs. Optional Extras
While comprehensive policies cover accidental damage, theft, fire, storm/flood damage, and legal liability (usually up to $20 million), peripheral inclusions differ:
* **Windscreen & Glass Cover:** Some policies include glass repair/replacement with zero excess, while others treat it as an optional extra.
* **Rental Car / Alternative Transport:** Check if a hire car is provided automatically or as an optional extra while your car is being repaired after an accident (or if it's only provided if your car is stolen).
* **Roadside Assistance:** Some brands include or offer low-cost add-ons for 24/7 breakdown help.
* **Extras for Personal Items:** Look for coverage limits on things left inside the car, replacement keys/locks, or child car seats.

### 5. No-Claims Discount (NCD) Protection
* Look at how the insurer handles your **No-Claims Bonus / Discount**. Some insurers offer NCD protection if you pay a little extra, meaning your discount won’t drop if you have an at-fault accident.
* Check policies regarding non-fault accidents: most won't penalise your discount if you are not at fault and can provide the other driver's details (registration, name, contact info).

### 6. New Car Replacement Criteria
* If you buy a brand-new car, many comprehensive policies feature a "new vehicle replacement" clause if it is written off within a certain timeframe. However, the exact thresholds differ (e.g., must be under 1 year old, under a specific kilometre limit, or purchased brand new by you).

### 7. Exclusions and Fine Print
* Carefully check what is **not** covered. Common exclusions include driving under the influence of drugs or alcohol, reckless driving, unlisted drivers (if restricted), or mechanical/electrical breakdowns due to standard wear and tear.

**Tip:** Because premiums vary widely depending on your age, location, and vehicle type, getting quotes from at least three different NZ providers allows you to compare both the cost and the fine-print benefits side by side.

When choosing **comprehensive car insurance in New Zealand**, you should primarily compare **how your car is valued (Agreed vs. Market Value)** , the **total policy cost (Premium + Excess)** , and the **specific benefits and policy exclusions**. Because average comprehensive premiums hover around **$1,311 per year** (as of Q2 2026), shopping around can save you hundreds of dollars.

* * *

1\. Valuation: Agreed Value vs. Market Value

This is the maximum amount the insurer will pay if your vehicle is written off:

 * **Agreed Value:** A fixed sum you and the insurer agree on when you take out or renew the policy. It provides financial certainty but can slightly increase your premium.

 * **Market Value:** What the car is worth on the open Kiwi market right before the accident. This amount depreciates over time, meaning your potential payout drops every month.

2\. Out-of-Pocket Expenses: Premium vs. Excess

 * **The Premium:** The regular cost to keep the policy active. Look out for promotional discounts—such as the digital Visa gift cards or sign-up discounts periodically offered by providers like AA Insurance, State, [Tower](https://www.tower.co.nz/car-insurance/), and Cove. Pay annually if possible, as it typically saves you 10% to 15% compared to monthly installments.

 * **The Excess:** Your financial contribution when making a claim. Opting for a higher voluntary excess (e.g., raising it to $1,000+) will lower your premium.

 * **Young Driver Excesses:** If you or anyone driving your car is under 25, insurers will add a substantial mandatory "under-25" excess on top of your standard excess.

3\. Core Benefits & Policy Inclusions

Standard comprehensive policies in NZ generally cover accidental damage, fire, theft, and third-party property damage. However, you should check if the following features are automatically included or require an extra fee:

Policy Benefit| What to Look For
---|---
**Windscreen & Glass Cover**| Look for **excess-free** glass cover. Some insurers bundle this in, while others charge it as an add-on.
**Roadside Assistance**| Breakdown towing and roadside rescue can cost an extra annual fee or come free with top-tier comprehensive policies.
**Courtesy / Hire Car**| Check if a rental vehicle is provided automatically while your car is being repaired, and note the time limits (usually 14 to 30 days).
**New Car Replacement**| For brand-new vehicles, many NZ insurers will replace the car with a factory-new model if it is written off within 12 to 24 months of purchase.
**Repair Guarantees**| Look for a **Lifetime Repair Guarantee** , which ensures any fix completed by an approved network repairer is warrantied for as long as you own the car.

4\. Third-Party Protections

 * **Legal Liability:** Ensure the policy provides at least $20 million in third-party property damage liability.

 * **ACC Context:** Note that you do not need car insurance to cover personal injuries in New Zealand. Personal injury costs from motor accidents are automatically covered by the **Accident Compensation Corporation (ACC)** through your vehicle registration levies.

 * **Uninsured Driver Extension:** Check if the policy protects you if an uninsured driver hits your car. Most comprehensive policies waive your excess if you can identify the at-fault, uninsured third party.

5\. Common Exclusions & Pitfalls

 * **Driver Licensing Conditions:** If you breach your licence conditions (e.g., driving after 10 PM or carrying unauthorized passengers on a restricted licence), your insurer will legally reject your claim.

 * **Mechanical Breakdown:** Comprehensive insurance does not cover mechanical failures or wear-and-tear; you need a mechanical breakdown insurance (MBI) policy for that.

 * **Vehicle Modifications:** Non-factory modifications (performance parts, custom paint, or wraps) must be explicitly disclosed. Unreported modifications can void your entire policy.

* * *

If you'd like to narrow down your options, tell me:

 * What is the **make, model, and year** of your vehicle?

 * Are there any drivers **under the age of 25** using the car?

 * Do you have **other insurance policies** (like house or contents) that you could potentially bundle?

When choosing comprehensive car insurance in _New Zealand_ , looking beyond just the monthly or annual price is essential. Policies vary significantly in their fine print, payouts, and extra benefits.

To make a thorough and effective comparison, evaluate the following key areas:

 * * **Agreed Value vs. Market Value:** Check how the insurer determines your payout if your car is written off or stolen. An _agreed value_ locks in a set amount for the year, whereas _market value_ means you receive what the car is worth at the time of the claim (which can depreciate and lead to surprises). [AMI Insurance]

 * **Excess Amounts and Options:** Look at the standard excess (the amount you pay upfront on a claim) and see if you can adjust it. A higher excess lowers your regular premium, but costs more if you have an accident. Check for special driver excesses too, such as extra fees for drivers under 25 or learners.

 * **Agreed vs. Lifetime Repair Guarantees:** See who handles the repairs and what guarantees they offer. Some major NZ insurers back repairs with a lifetime guarantee for as long as you own the vehicle, and allow you to choose or use their approved repairer networks.

 * **Additional Standard Inclusions:** Compare the hidden "extras" bundled into comprehensive tiers. Check policies for:
 * Emergency towing and transport home
 * Replacement or re-coding of lost or stolen keys (some offer this excess-free up to a certain limit)
 * New car replacement if your vehicle is brand new and written off within a specific timeframe
 * Statutory third-party property damage liability (typically up to $20 million)

 * **Optional Add-ons:** Review the cost and availability of optional extras like **Roadside Assistance/Breakdown Cover** , rental car cover following an accident or theft, and protected no-claim bonus/protection.

 * **Financial Strength Ratings:** Ensure the insurance provider holds a robust current financial strength rating (such as A or higher from agencies like **AM Best**) so you know they can reliably pay out large claims. You can check provider details through Consumer NZ or Canstar NZ. Best car insurance - compare premiums and policiesCompare Car Insurance Policies and Providers in NZ | Canstar

 * **Discounts and Promotions:** Compare how payment frequencies affect your total cost (some offer discounts for annual payments, while others offer promotional sign-up bonuses). Note that many major NZ insurers have phased out broad multi-policy discounts, so it pays to price each line item directly.
