Fuel quality monitoring

The quality of fuels sold in New Zealand is regulated by the Government for environmental, health and fitness-for-purpose outcomes.  The Engine Fuel Specifications Regulations 2008 provides mechanisms for the enforcement of fuel quality in New Zealand by Trading Standards.  Under this authority, Trading Standards monitors fuel quality and responds to complaints from consumers and rival oil companies.  Further details are available from the Consumer Protection and Standards branch within MBIE - Fuel Quality Monitoring

Specific fuel quality acts and regulations


The key Act of Parliament pertaining to the petroleum and fuel industry in New Zealand is the Energy (Fuels, Levies and References) Act 1989.  The distribution and sale of petrol and diesel in New Zealand has been deregulated since 1988. Prior to that, retail prices and margins had been regulated and fuel quality specifications were set by agreement between government, the oil industry and motor vehicle manufacturers.

Energy (Fuels, Levies and References) Act makes provision for regulations in relation to fuel quality and related matters such as specifications for refuelling equipment and vehicle refuelling inlets, and provision of information for consumers.


Regulations pertaining to the quality of petrol and diesel are made pursuant to the Ministry of Energy Act 1989.  The current regulations defining fuel parameters are the Engine Fuel Specifications Regulations.
