The Competition and Consumer Regulations 2010 are a legislative instrument made under the Competition and Consumer Act 2010. They do not replace the Act. Instead, they support it by setting out detailed operational rules that the Act relies on.
That hierarchy matters. The Act contains the main competition and consumer law framework, while the Regulations deal with many of the practical mechanics, including approved forms, how time is counted, service of documents, filing and review procedures, fees, prescribed particulars for registers, and specific consumer law requirements such as warning statements, gift cards, warranties against defects and repair notices.
If you are trying to work out your obligations, the safest approach is to read the relevant part of the Act together with the matching part of the Regulations. A business can easily miss a compliance step if it reads only the headline Act provision and not the detailed regulatory requirements that sit underneath it.
The instrument also expressly links to the Competition Code in some contexts. The interpretation provisions state that references to the Act or the Regulations can include the Competition Code where the law says so. For businesses operating across jurisdictions or dealing with competition law processes, that is another reason to check the exact legislative pathway rather than relying on a broad summary.
