The purpose of the study is to consider and evaluate whether competition in the retail fuel market is promoting outcomes that benefit New Zealand consumers over the long-term. The study is focused on the supply of retail petrol and diesel for use in land transport. We will not be evaluating fuel markets such as aviation or marine.

The terms of reference for the study can be found here.

We have been asked to publish our final report of our findings by 5 December 2019. These findings will be made publicly available and may include recommendations that identify ways to improve outcomes at the pump for New Zealand motorists.

Over the course of the study we will be engaging with, and gathering evidence from, a wide range of stakeholders, including the fuel industry, motoring groups, consumer bodies and consumers. Information relating to the study, including process updates, working paper(s), submissions and a timeline for our planned consultation steps, will be available through the links below as the study progresses.
