Market studies
The Commerce Amendment Act 2018 amended the Commerce Act 1986 (the Commerce Act) to give the Commerce Commission the ability to undertake market studies to determine whether there are any factors that may be impeding competition in a market.
Reviews of the Commerce Act 1986
We carry out periodic reviews of the Commerce Act to ensure it reflects modern regulatory practice and continues to deliver benefits to New Zealanders.
Retail payment system
We are working to ensure that the retail payment system operates in the interests of New Zealand consumers and businesses.
Consumer data right
The Government has decided to establish a consumer data right in New Zealand to give individuals and businesses greater choice and control over their data. We recently consulted on the draft law that will be used to enable this, and we are considering public feedback.
Economic regulation of goods or services
The regulation of the price and quality of goods or services in markets with monopoly characteristics is covered by Part 4 of the Commerce Act, and is implemented by the Commerce Commission.
Assessing competition impacts
We provide advice on the impacts of government policies and proposed regulation — including occupational regulation — on competition and consumers.
Monitoring the Commerce Commission
The Minister of Commerce and Consumer Affairs is the minister responsible for the Commerce Commission, and appointed us as its monitoring agent.
