Introduction
Selling a car in New Zealand isn’t just about getting a good price, it’s about doing it right.
Whether you’re selling privately in Waikato or trading in across the Bay of Plenty, there are a few legal boxes you must tick to stay safe and avoid liability.
This guide explains your key legal responsibilities as a private seller, what to include in a sale agreement, and how to protect yourself from common mistakes. We’ll also show you an easier way to sell your car legally, with help from CashForCar.nz.
Legal Requirements for Private Car Sales in NZ
Selling your car privately means you’re responsible for making sure the transfer and paperwork are done correctly.
Here’s what the law requires:
- Notify NZTA immediately after sale. Complete your side of the ownership change using the online form or MR13A paper form.
- Keep a record of the buyer’s details. Include their full name and licence number on a receipt or agreement.
- Declare if the car has no WOF/COF. You must disclose this clearly in writing (e.g., “sold without current WOF”).
- Clear any outstanding finance. If there’s a security interest on the car, you must settle it or inform the buyer.
- Don’t misrepresent the vehicle. Honesty isn’t just ethical, it’s a legal requirement under the Fair Trading Act 1996.
💬 Tip: If you sell to a licensed buyer like CashForCar.nz, they handle the ownership transfer and legal paperwork for you – so you’re protected from liability the moment you hand over the keys.
What to Include in a Private Car Sale Agreement (Quick Checklist)

✅ Full names and addresses of buyer and seller
✅ Driver licence numbers for verification
✅ Vehicle details > make, model, plate, VIN number, odometer reading
✅ Sale price and payment method
✅ WOF and registration status
✅ Any disclosures (e.g., accident damage, finance owing, mechanical issues)
✅ Signatures and date

Disclosure and Honesty Obligations
When you sell a car privately in NZ, you must be honest about its condition and history.
Key disclosures include:
- Mechanical issues or known faults – don’t hide problems; it’s better to be transparent.
- Previous accidents or repairs – if you know of damage, say so.
- Money owing or encumbrances – use the PPSR check
to confirm it’s clear. - Modified vehicles – state if the car has performance mods or structural changes.
Failing to disclose key facts can lead to complaints under the Fair Trading Act or Consumer Guarantees Act, especially if the buyer can prove you misled them.
Common Legal Mistakes to Avoid
❌ Not filing ownership change immediately – until it’s done, you’re still liable for fines or tolls.
❌ Selling a car with finance owing – this can be challenged by the buyer.
❌ Verbal agreements only – always get it in writing.
❌ False advertising claims – avoid phrases like “mint condition” if it isn’t.
❌ Forgetting to cancel insurance after sale.
