Road user charges (New Zealand)

Road user charges (RUC) are a tax paid by users of vehicles which use energy that is not taxed at its source (e.g., fuel tax).

Taxed fuels
Vehicles powered by petrol, compressed natural gas (CNG), and liquefied petroleum gas (LPG) generally do not pay RUC as these fuels are taxed at source. In New Zealand, other vehicles such as light diesel vehicles or trucks do pay RUC. Most large vehicles fall into this category.

Taxed vehicles
Vehicles required to pay RUC include:
 * Vehicles that have a manufacturer's gross laden weight of 3,500 kg (7,716 lb) or more
 * Vehicles that use diesel or other fuel not taxed at source

Payment
Charges are payable to the NZ Transport agency enforced by NZ police so all road users must ensure you have the correct documents displayed at all times in order to avoid a fine. There are several exemptions available for certain types of vehicles such as tractors however the vast majority of larger vehicles will be required to pay RUC.

Details on payment can be found on the New Zealand Transport Agency Website. http://www.nzta.govt.nz/vehicle/registration-licensing/ruc/overview.html
