In New Zealand, yes, some car insurers let you choose your own repairer, but others require you to use an approved repairer or get their agreement first. It depends on your insurer, your policy wording and whether you're claiming under your own insurance or someone else's.

If your car is written off, the insurer will generally settle the claim financially rather than repair it. The important questions are how they calculate the payout, whether you can challenge the write-off decision, and what happens to the wreck.

## 1. Can you choose your own repairer?

There are three common arrangements:

- Free choice of repairer: You can nominate your preferred panel beater or mechanic, subject to the insurer's approval and any policy conditions.
- Approved repairer network: The insurer directs you to a repairer in its network. Using an outside repairer may require prior approval or could affect cover for repair costs or workmanship guarantees.
- Insurer-approved quote: You nominate a repairer, but the insurer assesses the damage and agrees to the repair scope and price before work begins.

Even if you can choose your repairer, you generally shouldn't authorise expensive repairs before the insurer has assessed the vehicle.

Tip: Before buying or renewing a policy, ask: “Can I choose my own collision repairer, and will you pay their full reasonable repair cost if they aren't in your network?”

For example, New Zealand insurers differ in their approach:

- MAS explicitly offers the choice of a preferred repairer or a repairer of your own choosing. Its repair guarantee applies to preferred repairers. [Motor Vehicle Insurance Policy Details](https://www.mas.co.nz/insurance/motor-vehicle-insurance/motor-vehicle-insurance-policy-details/)
- NZI has policy wording that allows it to arrange repairs itself or pay its estimate of reasonable repair costs so you can use your own repairer. Choosing your own repairer doesn't necessarily mean the insurer will cover whatever price they quote. [Distinction Motor Vehicle Insurance / Policy wording](https://www.nzi.co.nz/documents/distinction-car-policy)
- AA Insurance says it uses its own group of repairers when it arranges repairs under the relevant policy.

Always check the specific policy wording, as products and conditions can change.

## 2. What happens if your car is written off?

Step 1: The insurer assesses the damage

The insurer decides whether the car can be repaired safely and economically. If the repair cost makes repairing it uneconomic compared with settling the claim, it may declare a total loss, or write-off. [Third Party Car Insurance | Quote & Buy Online](https://www.state.co.nz/car-insurance/third-party)[What happens if my vehicle is written off or is a total loss?](https://www.aainsurance.co.nz/help/article/5698660041615-What-happens-if-my-vehicle-is-written-off-or-is-a-total-loss)

Step 2: They calculate your payout

The amount usually depends on whether your policy covers the car for an agreed value or market value, plus any applicable excess, outstanding premiums and other permitted deductions. [Car insurance](https://www.consumerprotection.govt.nz/help-product-service/cars/paying-registering-insuring-car/car-insurance)[What happens if my vehicle is written off or is a total loss?](https://www.aainsurance.co.nz/help/article/5698660041615-What-happens-if-my-vehicle-is-written-off-or-is-a-total-loss)

Step 3: The insurer usually takes ownership of the wreck

Under many policies, once the total-loss claim is settled, the damaged vehicle becomes the insurer's property. You generally cannot keep it automatically, although you can ask whether buying it back is possible. [Third Party, Fire & Theft Car Insurance Policy](https://www.aainsurance.co.nz/manage-policy/policy-documents/third-party-fire-theft-insurance-policy-document)[1. we’ll pay you the agreed value for your car, if that is the cover type shown on your certificate of insurance](https://www.tower.co.nz/wp-content/uploads/2021/03/car-comprehensive-04-21.pdf)

### How much would you get paid?

The key distinction is your type of cover.

| Cover type | How the payout is calculated |
| --- | --- |
| Agreed value | The amount specified in your policy schedule, subject to policy terms and deductions. |
| Market value | What the car was worth immediately before the loss, assessed using factors such as age, model, mileage and condition. |

Example: Suppose your car has an agreed value of $15,000 and your applicable excess is $500. If no other deductions apply, your payout would be $14,500.

With market-value cover, the insurer might assess the same car at $12,000, giving you $11,500 after the same excess.

If you have a car loan, check how the settlement is applied: the lender may be paid first, and you could still owe money if the payout doesn't clear the loan.

## 3. Can you challenge a write-off decision or payout?

Yes, you can raise a dispute if you think the valuation is too low or the decision hasn't properly considered the damage and repair options.

Practical steps:

1. Ask for the assessor's report, including the repair estimate and the basis for declaring the vehicle uneconomic to repair.
2. Check comparable vehicles for sale in New Zealand, matching your car's year, model, trim, mileage and condition.
3. Provide evidence of its condition and value, such as service history, recent work, options and modifications.
4. Ask for a review in writing if the valuation or decision appears unreasonable.

If you cannot resolve the complaint internally, check which independent dispute-resolution scheme your insurer belongs to. New Zealand's Consumer Protection website also explains the differences between market-value and agreed-value cover.

## 4. What I'd check before choosing an insurer

If being able to use your own repairer matters to you, compare these four things:

- Repairer choice: Is it an unconditional choice, or does the insurer have to approve the repairer and quote?
- Repair guarantee: Does the guarantee still apply if you use an independent panel beater?
- Write-off threshold: How does the policy define an uneconomic repair, and who decides?
- Settlement terms: Is your car insured for agreed or market value, and can you retain the wreck if it's written off?

You can start with the official policy information from [MAS](https://www.mas.co.nz/insurance/motor-vehicle-insurance/motor-vehicle-insurance-policy-details/), [AA Insurance](https://www.aainsurance.co.nz/) and [NZI](https://www.nzi.co.nz/).

One important question: Are you looking to choose an insurer before buying a policy, or has your car already been damaged and you're dealing with an existing claim? The practical options are quite different in those two situations.

In New Zealand, the rules around choosing your own repairer and dealing with a write-off depend on your specific insurance policy, though standard industry practices apply across most major providers (such as AA Insurance, AMI, State, and Initio). 

---

### Choosing Your Own Repairer

* **Can you choose?** Yes, as a vehicle owner in New Zealand, you generally have the right to choose which panel beater or repairer looks at your car. 
* **The Catch:** While you can send the car to your preferred repairer, your insurance company will usually only cover the costs up to a competitive, fair market rate to bring the vehicle back to its pre-accident condition. If your chosen repairer charges higher labor rates or parts costs than what the insurer's approved network charges, you may have to pay the difference out of pocket.
* **Approved Networks:** Most insurers strongly encourage using their "preferred" or "approved" repairer networks. Going with an approved repairer often comes with perks like a lifetime guarantee on workmanship, streamlined pre-authorisation (faster turnaround), and a guaranteed loan car while your vehicle is in the shop.

### What Happens If Your Car Is Written Off?

A vehicle is typically declared a total loss (write-off) if the estimated cost of repairs exceeds its insured value, or if the structural/safety damage is too severe to fix economically. 

1. **Assessment & Payout Valuation:** 
   An assessor will evaluate the damage. If it's a write-off, the insurer will pay out based on your policy type:
   * **Agreed Value:** You receive the fixed amount specified on your policy schedule (minus your excess).
   * **Market Value:** You receive the estimated cash value of the car immediately before the accident occurred (minus your excess). *(Note: If you disagree with their market valuation, you can provide evidence of recent comparable sales/listings to negotiate).*
2. **Ownership of the Wreck:** 
   Once the insurer pays out the total value of the car, they take ownership of the salvage (the wreck). In some cases, you can negotiate to "buy back" the salvage, but the car will be deregistered.
3. **Deregistration:** 
   The insurance company is legally obligated to have the vehicle deregistered on the Motor Vehicle Register to ensure severely damaged or unsafe vehicles do not return to NZ roads without proper certification. 
4. **Outstanding Finance:** 
   If you have a car loan or finance on the vehicle, the insurance payout goes toward clearing that debt first. If the payout is less than what you owe, you remain personally responsible for paying off the remaining balance (unless you held GAP insurance).

Yes, **New Zealand car insurers generally allow you to choose your own repairer**, but doing so comes with specific financial rules. If they write the car off, it is treated as a **total loss** , and the policy is effectively finalized with a cash payout. canstar.co.nzWhat Happens if Your Car is Written Off in NZ? | CanstarIn New Zealand, You Can Choose Your Own Repairer forWhat happens if my vehicle is written off or is a total loss?

Here is exactly how both situations work under New Zealand insurance standards.

* * *

1\. Choosing Your Own Repairer

While major Kiwi insurers (like AA Insurance, AMI, Vero, and Tower) prefer you use their network of "approved repairers," you have the right to request your own panel beater. aainsurance.co.nzCan I choose my own vehicle repairer? - AA InsuranceVehicle InsuranceVehicle Repairs | VeroCan I drive an uninsured car? - Tower InsuranceCar insurance: How to make a claim

However, you must be aware of the following conditions:

 * **Cost Caps:** If your chosen shop quotes higher than the insurer's internal assessors or what their network would charge, the insurer will usually only pay out the **lower, reasonable cost**. You will have to pay the difference out of pocket.

 * **No Insurer Guarantee:** If you use an approved network repairer, the insurer guarantees the repairs for the lifetime of the vehicle. If you choose your own independent repairer, you lose that insurer-backed lifetime guarantee (though you are still protected under the Consumer Guarantees Act (CGA) for quality of service). consumer.org.nzComprehensive Car insurance | AMP New ZealandCar insurance buying guide | Consumer NZ expert advice

 * **Pre-Approval Needed:** Never let a workshop begin work until your insurer has formally approved the repair plan and quote in writing.

2\. What Happens if the Car is Written Off?

An insurer declares a car a **total loss** (written off) if it is unsafe to drive or if the cost of repairs approaches or exceeds the vehicle's actual value (often starting around the 50%–70% threshold).

If this happens, the following process takes place:

Step| What Happens
---|---
**The Payout**| The insurer pays you either the **Agreed Value** or the **Market Value** , depending on what is specified in your policy schedule.
**Deductions**| The insurer will subtract your **excess** from the payout. They will also deduct any **outstanding insurance premiums** left for the remainder of your annual policy term.
**Ownership of the Car**| The **insurer takes legal ownership** of the vehicle and its wreck. They will cancel the car's registration with [Waka Kotahi (NZTA)](https://www.nzta.govt.nz/vehicles/not-using-your-vehicle/insurance-claims) and typically sell the remains to a wrecker or a damaged-vehicle auction.
**Policy Closure**| Once a total loss payout is made, your insurance policy for that vehicle is considered fully fulfilled and is **cancelled automatically**. You do not get a refund for the remaining months of the policy.
**Car Loans**| If the car is under finance, the insurance payout goes **directly to the finance company** first. If the payout doesn't cover the full loan amount, you remain legally responsible for paying off the remaining debt.

If you are currently dealing with a claim, let me know:

 * Which **insurance company** you are with

 * If your policy is for **Agreed Value** or **Market Value**

I can give you more specific details on how they calculate their payouts.

Choosing Your Own Repairer in New Zealand

Yes, most New Zealand car insurance policies allow you to choose your own repairer, but there is a major catch regarding guarantees and costs:

 * * **Using an Approved/Preferred Repairer:** If you use an insurer's recommended or approved network, they will typically **guarantee the quality of the workmanship and parts** for as long as you own/register the vehicle. The process is streamlined since the insurer deals with them directly.

 * **Using Your Own Repairer:** You have the right to request your own local or preferred mechanic/panelbeater. However, insurers will usually cap their payout at what it _would_ have costed them using their own approved network (or the lowest quote from their assessor). If your chosen repairer charges more, **you may have to pay the difference**.

 * **No Insurer Guarantee:** If you use your own unapproved repairer, the insurance company generally **will not guarantee** their workmanship; any dispute over the quality of the fix falls back on you and the repairer (under the [Consumer Guarantees Act](https://www.consumer.org.nz/articles/consumer-guarantees-act)).

What Happens if the Car is Written Off?

If an insurer's assessor determines that the cost to repair the vehicle is uneconomical, or if the car is structurally unsafe and damaged beyond safe repair, it is declared a total loss (written off). The settlement process in New Zealand involves the following steps:

 1. **Valuation and Payout Calculation:**
 * **Market Value:** Most policies pay out the current market value (what the car was worth immediately before the crash), minus your excess.
 * **Agreed Value:** If your policy specifies an agreed value, they pay that fixed amount (minus your excess).
 2. **Deductions:** The insurer will subtract your agreed **excess**. If you pay your annual insurance premium on a **monthly** installment plan rather than a lump sum, they will also deduct the remaining balance of that year’s premium from your payout.
 3. **Ownership Transfer & Deregistration:** Once a total loss is settled, ownership of the wreck transfers to the insurance company, and they will officially deregister/cancel the vehicle's registration with [NZ Transport Agency Waka Kotahi](https://www.nzta.govt.nz/).
 4. **Outstanding Finance:** If you have a car loan or finance on the vehicle, the insurance payout goes toward clearing that loan first. If the payout is less than what you owe on the loan, **you are still responsible for paying off the remaining balance** (unless you hold specialized GAP insurance).

If you want to check specifics for your situation, let me know:

 * **Who your insurance provider is**
 * Whether your policy is **Market Value** or **Agreed Value**

I can give you a clearer idea of how they handle claims and payouts.
