Selling your old or damaged car to a wrecker is one of the easiest ways to turn an unwanted vehicle into instant cash. But before you hand over the keys, there’s one crucial step you shouldn’t overlook: deregistering your car with NZTA.
Getting this wrong can leave you liable for fines, rego fees, and legal issues long after your car is gone. The good news? It’s a straightforward process—especially when you sell to a professional wrecker like Speedy Cash Cars who handles the paperwork for you.
Here’s everything you need to know about deregistering your car in NZ when selling your vehicle to a wrecker.
What Does “Deregistering” a Car Actually Mean?
Deregistering (also called “cancelling registration”) means your vehicle is officially removed from the NZ motor vehicle register. Once deregistered, the car:
Can no longer be legally driven on public roads
No longer requires a WoF or registration
Is no longer your legal responsibility in terms of rego, licensing, or fines
Can be dismantled, scrapped, or recycled by a licensed wrecker
You can only deregister a vehicle if it’s being permanently removed from the road—which is exactly what happens when you sell to a wrecker.
Why Deregistering Matters When Selling to a Wrecker
Many sellers assume that once the wrecker drives away with their car, their obligations end. That’s not the case.
Until the vehicle is officially deregistered or the ownership is transferred, you may remain liable for:
Unpaid registration fees
Parking or traffic infringements incurred by whoever possesses the car
Legal liability if the vehicle is involved in an incident before it’s processed
Deregistering your car—or ensuring the wrecker completes the ownership transfer—protects you from these headaches.
Who Can Deregister a Vehicle in NZ?
You can deregister a vehicle if you are:
The registered person (the name on the registration)
The owner of the vehicle
Acting with written authorisation from the registered person
A licensed motor vehicle dealer or authorised agent
If there’s money owing on the car, you must get written consent from the finance company before deregistering.
How to Deregister Your Car in NZ: Step-by-Step
There are two ways to deregister your vehicle—online or in person. Here’s how each works.
Option 1: Deregister Online via NZTA
The fastest method is through the NZTA online portal:
Go to the NZTA website and log in (you’ll need your NZTA login or RealMe account)
Select “Deregister a vehicle”
Enter your vehicle details (plate number or VIN)
Confirm the reason for deregistration (e.g., “vehicle being wrecked/dismantled”)
Submit the application
Receive confirmation – NZTA will update the register
What you’ll need:
Your driver licence or NZTA customer number
The vehicle’s registration plate or VIN
Proof you’re the registered owner (or authorisation)
Important: If the vehicle is being wrecked, the wrecker can often do this for you as part of the sale.
Option 2: Deregister in Person
You can also visit an NZTA agent (like a VTNZ or AA branch) and complete a MR15 form (Application to Cancel Registration).
You’ll need:
Photo ID
Proof of ownership
The vehicle’s number plates (you must surrender them unless they’re being transferred)
Payment of any outstanding fees
What About the Number Plates?
When you deregister a vehicle, the number plates must be surrendered (unless you’re transferring them to another vehicle).
Standard plates: Hand them to the wrecker or NZTA agent
Personalised plates: You can usually retain these for future use—just let the wrecker know
Euro-style or special plates: Check with NZTA about retention rules
If you sell to a professional wrecker like Speedy Cash Cars, we’ll guide you on what to do with your plates.
Do You Need to Deregister If the Wrecker Handles the Transfer?
Not necessarily. When you sell your car to a licensed wrecker, there are two possible paths:
| Scenario | What Happens | Your Responsibility |
|---|---|---|
| Ownership transfer | Wrecker becomes the registered owner | Ensure they complete the transfer online |
| Deregistration | Vehicle is removed from the register entirely | Provide authorisation; wrecker submits the deregistration |
| You deregister first | You cancel registration before the sale | Complete the NZTA process yourself |
At Speedy Cash Cars, we handle the ownership transfer and deregistration paperwork on your behalf—so you don’t have to deal with NZTA at all.
What Happens If You Don’t Deregister?
Failing to deregister or transfer ownership can have real consequences:
You may keep receiving infringement notices for a car you no longer own
You could be liable for unpaid rego accrued after the sale
You may face fines for failing to notify NZTA of the change
The vehicle could be used illegally and traced back to you
It’s not worth the risk. Always ensure the paperwork is completed correctly.

| Deregistration | Wrecker handles it | You must handle it |
| Towing | Free removal provided | You arrange transport |
| Payment | Instant cash on collection | Depends on buyer |
