There is helpful information on the Ministry for Consumer Affairs website. We don't act on behalf of individuals. The Commission investigates issues that are in the public interest. While your complaint may spark an investigation, we won't be acting on your behalf, rather as a public enforcement agency. We don't give legal advice. But we do provide guidelines and fact sheets, which are on this website, to help you understand the legislation we enforce and how we work. Alternative sources of advice can be: You can also access other disputes resolution and investigation agencies at Complaint Line . We don't investigate every complaint. We receive around 10,000 enquiries and complaints a year. Up to a quarter of these are not issues we have the mandate to deal with. Of the remainder, we have to pick those cases to investigate where the public harm is highest. Requesting confidentiality You may feel that informing the Commission about possible wrong doing might put your position at risk (for example you may be an employee or trading partner of the person or organisation you want to complain about). If you are concerned about the need to protect your identity, please raise it with us when you make your complaint. We value information from confidential informants and have a strong policy of protecting people's identity when requested. How to complain If your complaint belongs with us, you can fill in our online form , or call us on 0800 943600.
