It doesn't even have to be linked to the car tax.
NZ uses "Road User Charges" for diesel - it does not have the tax built in at the pump (petrol does), so all diesel cars have to buy blocks of kilometres as tax. The government get updated when your annual vehicle inspection is done, but between those inspections its up to you to make sure you have enough spare kilometres left for your trips. If you get stopped by police and they check, being too far out is considered to be tax evasion and a criminal offence.
