Competition and Consumer Investigation Guidelines

The Commission believes it is important that people who interact with us, in the context of an investigation, know what to expect.

This page should be read in view of amendments to the Commerce Act and the Commerce Act (Fees) Regulations made in August 2017. The Commission will update the page in the near future to reflect changes made under the Act.

We have drafted our investigation guidelines in plain English and in an easy-to-follow format so that our investigation processes are accessible to everyone.

Whether you are a consumer who has made a complaint, a business being investigated, someone helping us with an investigation, or a lawyer representing a business, you now have access to detailed information about our processes and what you can expect.

The guidelines cover a wide range of topics, such as:

  • who we are and how we make decisions
  • how we go about getting evidence and information
  • what compulsory powers we have and how we decide to use them
  • whether and when we will do media statements or provide public information about an investigation.

A set of five investigation principles that guide how we investigate are outlined in the guidelines. These principles deal with matters like fairness, timeliness, openness and accountability, outlining the standards that we strive to reach in our investigations.
