Opposition is growing to a new fee that will soon be payable for getting basic information about vehicles.
In January, the Transport Agency will begin charging for information about odometer readings, vehicle registrations and warrants of fitness.
A dozen automotive, finance and advocacy groups are now protesting against the new charge.
Among them is Consumer, whose spokesperson Hamish Wilson says the agency is double-dipping, because the details are from a database made up of information collected when people register their vehicles - for which they pay a heavy fee.
While the proposed fee is just 2 cents for an overnight service and 16 cents for an immediate report, Mr Wilson says any cost will deter people from using the service, opening the door to people selling dodgy vehicles.
However Transport Agency spokesperson Andy Knackstedt says the introduction of the charge is just one part of a restructuring of fees, in which 90% of charges are being reduced and one small new levy is being introduced.
He says the new fee reflects the actual cost of providing the information.
Mr Knackstedt says the motor check service has always been self-funding and has never been paid for by vehicle registrations.
