Vehicle fuel economy labels
Motor vehicle traders must display fuel economy labels on all vehicles (except for electric vehicles), provided a fuel economy label is available. If you’re looking at an online vehicle listing, you may see a smaller version of the label or the information displayed as text.
Using fuel labels to compare cars
There can be a big difference in fuel consumption between cars of the same or similar size. The star rating and indicative cost per year helps you to easily compare one car to another. Medium sized cars often offer you the same comfort and safety features as a large car, but use less fuel.
The fuel economy label gives you an indication of the fuel consumption based on international rolling road test-lab drive cycle testing - UN ECE R101 (European NEDC), ADR (Australia), and JC08 (Japan). These tests are designed to test fuel consumption in lab conditions to make comparisons easier. Actual fuel economy will depend on a wide range of factors including your driving style and habits, speed and distance travelled, vehicle load, tyre pressure and level of maintenance.
You can compare fuel efficiency and safety ratings on the New Zealand Transport Agency’s RightCar website.
The most fuel efficient car available in New Zealand is an electric vehicle, find out more about EVs on the electric vehicles website.
What fuel labels tell you
- Vehicle make and model.
- Star rating - up to 6 stars for the most fuel efficient vehicles. The star rating will help you to compare one vehicle against another and to choose a vehicle that is more fuel efficient.
- Estimated cost per year to run the car – this comparative running cost is based on average fuel price and driving 14,000km per year. For diesel vehicles this cost also includes Road User Charges.
- Fuel economy in litres per 100km – provided by the vehicle manufacturer who obtains the data from international rolling road cycle testing, based on performance of a new model of the car.
- Reference number - confirms that the label refers to the vehicle it’s displayed with.
- Average fuel price - used to calculate the cost per year for comparison purposes only.
Fuel labels for electric cars
You can use the label for electric cars to compare efficiency and running costs with other types of car. The electric car label differs slightly:
- fuel economy for electric cars is shown in kilowatt hours per 100km
- information includes a range showing how far the car can be expected to go on a full charge
- displaying the label is optional for dealers.
Use our vehicle total cost of ownership tool to compare electric vehicles with petrol or diesel vehicles.
Using fuel labels to sell cars
Fuel economy label generator
Use our vehicle fuel economy label generator to get vehicle information and produce fuel economy labels, which can be printed on ordinary A4 paper in either colour or black and white.
If you’re selling a car privately online, you must make sure fuel economy information is displayed accurately (if it’s available). When you’re selling your car on trading websites such as Trade Me and AutoTrader, vehicle information might be automatically displayed as part of the vehicle's listing. The information you need to display is:
- vehicle make and model
- star rating out of six star
- cost per year to run the car
- fuel economy in litres per 100km.
Advertised sales and trade-ins
You don’t have to provide fuel economy if you’re selling a vehicle as a trade-in or advertising it in a newspaper. But it’s useful information for buyers, so use our vehicle fuel economy label generator.
