The moment after a car accident, your mind races. You’re checking if everyone is OK, wondering who’s at fault, and already worrying about the cost of repairs. What you do in the next half hour can make a real difference to how your insurance claim plays out and whether you end up paying more than you need to. For New Zealand drivers, the steps you take immediately after a crash don’t just affect your safety — they directly affect your wallet.

Most people don’t think about their insurance policy while they’re sitting on the side of the road. But the difference between a smooth claim and a headache often comes down to what you do before you even pick up the phone to your insurer. Knowing what information to collect, who to call, and what your policy actually covers can save you hundreds or even thousands of dollars. Here’s what you actually need to know.
One term you’ll hear repeatedly after an accident is your excess — the amount you pay towards any claim. It’s the figure that determines how much comes out of your pocket before your insurer pays the rest.
What I tend to notice is that most people don’t know their excess figure until they’re filing a claim. It’s worth checking your policy documents now so there are no surprises later. The difference between a $300 excess and a $1,000 excess can change how you approach a claim entirely.
What Different Insurance Covers Actually Cost You in Practice
Your insurance policy is a contract, and the fine print matters more after an accident than at any other time. The key financial figures are your excess, the policy limit, and whether you have rental cover. If you’re not at fault, the other driver’s insurance should cover your costs — but only if they’re insured and you have the right evidence to prove liability.

| Scenario | Who pays your repair costs | What you still owe |
|---|---|---|
| You’re at fault (fully insured) | Your insurer covers repairs | Your excess (e.g. $500) |
| You’re not at fault, other driver is insured | Other driver’s insurer covers repairs | Nil — provided liability is accepted |
| You’re not at fault, other driver is uninsured | Your own insurer (if you have uninsured motorist cover) | Your excess, unless your policy waives it for not-at-fault claims |
| You have third-party only cover and you’re at fault | Your insurer pays the other party’s damages — not yours | Full cost of your own repairs |
One thing worth weighing here is whether you have rental car cover as part of your policy. If your vehicle is off the road for a week and you need a replacement, that cost adds up fast. Some insurers offer it as an add-on, and if you’re not at fault, the other driver’s insurer may cover a replacement vehicle — but you need to ask for it. Companies like Right2Drive provide replacement vehicles at no cost to you if the accident was caused by another insured driver, while your car is being repaired or written off.

Where People Get It Wrong After a Car Accident
Even with good intentions, people make mistakes in the heat of the moment. The research shows there are a few specific errors that come up again and again, and each one can cost you money or complicate your claim.
Not collecting enough information at the scene
You need more than just a name and phone number. The research from compare.org.nz lists full name, driver licence details, mobile number, email, residential address, car registration, make, model, colour, insurance provider name, and policy number. A photo of the other driver’s licence front and back covers most of this in one go. Without their insurance policy number, your insurer has to track them down separately, which can slow everything down by days or weeks.
Forgetting to photograph the scene properly
Photos of the vehicles alone aren’t enough. You need the accident location, road signs, weather conditions, skid marks, and any visible damage from multiple angles. The research from right2drive.co.nz specifically mentions photographing the other driver’s registration plate, both vehicles in full, and the location including road signs and traffic lights. Video footage and dashcam recordings are even better. If the other driver later changes their story, your photos are the only evidence you have.
Admitting fault or agreeing to a settlement on the spot
At the scene, you might feel pressured to apologise or agree on who caused the accident. Don’t. Fault is determined by your insurer and the other party’s insurer based on evidence, not by what you say at the roadside. Anything you say can be used in the claims process. Stick to exchanging details and collecting evidence. Let the insurers sort out liability.
Delaying notification to your insurer
Some people wait a day or two to call their insurer, thinking they need to have all the details first. That’s a mistake. Notify your insurer as soon as possible after the accident, even if you’re still gathering information. They can tell you exactly what they need and start the process. Delayed notification can give your insurer grounds to question the claim or deny cover if your policy has a notification clause.
What I’d add is that the most costly mistake I see is people with third-party cover assuming they’re fully covered. If you’re at fault with third-party only, your own vehicle’s repair costs come entirely out of your pocket. That’s a bill that can run into thousands. A quick look at common car insurance gotchas can help you avoid this kind of surprise.
How to Handle the Aftermath Step by Step
Once you’ve stopped and checked for injuries, the process from there is straightforward if you follow the right order. Here’s what to do at each stage, with the insurance angle in mind.
Immediately after stopping: safety, legal requirements, and first evidence
Turn off your ignition and switch on hazard lights. If it’s safe, move the vehicle to the side of the road. Pin your location on a map app and screenshot it — this confirms the time and location later. Under New Zealand law, you’re legally required to stop, assist any injured persons, and provide your details to all other involved parties. If anyone is injured, call 111 immediately and request an ambulance. If the vehicle needs towing, or there’s damage to unattended property like a parked car or fence, call 111 and request police attendance. The same applies if the other driver refuses to give their details.
Gathering the details that matter for your insurance claim
Start with the other driver: full name, residential address, driver licence (take a photo of front and back), mobile number (confirm by calling it), and email address. Then the vehicle: registration number, make, model, colour, insurance provider name, and policy number. Then the scene: photograph both vehicles from multiple angles, the accident location, road signs, traffic lights, weather conditions, and any skid marks. If there are witnesses, get their full name, phone number, email, and address. In New Zealand, recording a conversation is legally permitted, but it’s best to inform the other person to avoid misunderstandings. If you have a dashcam, save the footage immediately.
Contacting your insurer and starting the claim
Call your insurer as soon as you have the basic details. They’ll ask for everything you’ve collected, so having it organised saves time. Provide the other driver’s insurance details if you have them. Your insurer will tell you the next steps, which usually include arranging an assessment of the damage, getting repair quotes, and confirming your excess. If you have rental car cover, ask about it now. If you’re not at fault and the other driver is insured, you may be eligible for a replacement vehicle at no cost to you while your car is off the road. Right2Drive offers this on 0800 004 203 — call them before you arrange towing, as they can coordinate the replacement vehicle and towing together.
What happens if the other driver is uninsured or disputes fault
If the at-fault driver has no insurance, you’ll need to rely on your own policy. Check whether you have uninsured motorist cover — this is an add-on that covers your costs when the other party has no insurance. If you don’t have it, you’re left pursuing the other driver directly for compensation, which can be a long and uncertain process. If fault is disputed, your insurer will investigate based on the evidence you collected. Photos, witness statements, and dashcam footage become critical here. If you’re stuck in a dispute, getting legal advice can help. Services like JustAnswer Finance can connect you with someone who understands the claims process.

What This Means for Your Next Drive
The single most useful thing you can do right now is check your policy documents. Know your excess, know whether you have rental cover, and know whether you’re covered for uninsured drivers. The research is clear: most people only learn what their policy covers when they file a claim, and that’s the worst time to find out you’re underinsured. A dashcam is one of the cheapest ways to protect yourself — it costs less than a single excess payment and can provide the evidence that settles a dispute in minutes. If you don’t have one, a dashcam for recording accident evidence is a practical investment.
