All vehicles that run on a fuel that does not have an excise at the pump (eg diesel), or weigh more than 3.5 tonnes, are subject to road user charges (RUC). To find out the reason for the differences in charges for petrol and diesel vehicles, visit the light petrol vs diesel page.
Calculate your Road User Charges below or alternatively download a version of our Excel RUC calculator spreadsheet [XLS, 90 KB].
This calculator is for information purposes only. To buy a RUC distance label visit the transaction centre of the NZ Transport Agency(external link).
To use this calculator, you first need to know your vehicle's type and its 'RUC weight'.
The Road User Charges Act defines RUC weight as the lesser of the:
- gross vehicle mass for the RUC vehicle
- maximum allowable mass for the RUC vehicle under section 4.5(1) of Part 1 of the Vehicle Dimensions and Mass Rule 2002(external link).
If you do not know your vehicle's RUC weight, you should contact the NZ Transport Agency(external link).
RUC calculator for rates from 1 October 2018
