Registration: The process of adding a vehicle to the Motor Vehicle Register: a vehicle, whether new or used, must first be registered before it can be licensed to be used on the road. Registration has been traditionally confused with licensing: registration is normally carried out only once in the lifetime of a vehicle, whereas licensing is generally renewed every six or twelve months.

Many fields on the Motor Vehicle Register (MVR) are free text fields and may therefore be subject to spelling mistakes and other human error. The NZTA have algorithmically cleaned the data to correct identified errors, it should be noted that due to the large number of vehicles on the register, some information may not have been corrected in this data.

The data represents the total registered fleet. Inside the registered fleet, there are vehicles that are currently licensed, and those that are not.

The data excludes any vehicles that have been deregistered from the MVR and the ones that were never registered in the first place.
