Anyone using New Zealand’s roads contributes towards New Zealand road upkeep. Most road users pay levies when they buy fuel and these are included in the fuel price, this is not the case for diesel fuel in New Zealand. Owners of vehicles such as light diesel vehicles and heavy vehicles like trucks, will pay through road user charges (RUC). The revenue collected from road user charges is dedicated to the National Land Transport Fund (NLTF). The NLTF funds road improvements and maintenance, public transport, road safety, and walking and cycling.
Vehicle owners have pre-purchased a set amount of RUC to ensure themselves and their guests are always within the legal limit while travelling, and as a guest you will need to pay back the amount of this pre-purchased RUC that you use on your trip. This amount will be calculated and charged by the owner via the post-hire checklist at the rate of $0.09 per kilometre driven ($9 for 100 kilometres).
Please note that as the levies that are included in the price of other fuels (such as petrol) are not included in the price of diesel at the pump it will appear significantly cheaper than other fuel types, this difference in price is made up by the road user charge.
