Both MR-13A and MR-13B forms are required to complete the Change of Ownership transaction.
In this case the previous owner has completed the MR-13A form advising that they have sold the vehicle to another party. However, the current owner has not completed an MR-13B form to agree to accept ownership and liability for the vehicle. Hence the current vehicle owner is not yet officially known, and the previous owner is still technically responsible for the vehicle's parking tickets, fines, etc
We suggest that both you (the new buyer) and the current owner (seller) visit an NZTA agent (for example VTNZ or NZ Post) and complete the Change of Ownership procedure. Having the seller present is not a legal requirement.
The current owner has completed the required MR-13B form indicating that they have taken responsibility for the vehicle.
However, they have not proved conclusively who they are by presenting suitable identification to an NZTA agent (for example driver's licence or passport).
We suggest that both the seller and the new owner visit an NZTA agent (for example VTNZ or NZ Post) and complete the Change of Ownership procedure.
The current registered owner has owned the vehicle for only a short period of time.
If they are not a registered motor vehicle trader then you should question why they are selling the vehicle so soon after purchasing it.
There could be mechanical or legal issues that you need to be aware of.
* have an independent mechanical inspection from Vehicle Testing New Zealand (VTNZ) to check for mechanical faults
* establish proof of ownership
The NZTA may have sent the owner mail that was returned stating that the vehicle's current owner is no longer at the address.
If you decide to buy the vehicle, make sure you see some form of identification that shows the owner's full name and current address.
