Before you make a complaint, please consider the following information about our service:

We generally cannot take action on your behalf

We are not a dispute resolution service and generally cannot assist you to get a refund or personal remedy. We cannot give you legal advice. Other organisations may be able to assist you in resolving your individual dispute, including Consumer Protection, the Citizens Advice Bureau or one of your local Community Law Centres – you can find more information on our website. Our website also provides information about your rights as a consumer and information about consumer and competition law. Please take a look at our guidance for consumersbusinesses, and regulated industries.

We will assess the information you provide, but do not investigate every complaint we receive

We assess every complaint we receive, but we are unable to investigate all of them. Our focus is to make sure New Zealand markets work well and consumers and businesses are confident when buying or selling goods and services. This means that we tend to be most interested in the issues causing widespread harm to New Zealanders. Complaints like yours help us to identify these issues.

If you contact us to complain about a business or person you believe has breached consumer and/or competition law, we then consider your complaint according to our enforcement criteria. We receive thousands of complaints each year and do not respond to everyone who contacts us with a complaint. If we need more information we will be in touch with you.

Complaints about the Commerce Commission

If your complaint is about the Commission itself, the complaint will be read, logged and assigned to a manager to answer. The manager will make contact with you and may seek further information.

Please see the Complaints Policy for information on how we handle complaints about the Commission.
