Regulated industries
The Commerce Commission regulates markets in New Zealand where there is little or no competition.
In this section
Our role in regulated industries
Our role as an organisation is more extensive in certain industries that are essential to everyday life and the economy – including electricity, gas, and telecommunications.
Grocery
The Commission has responsibilities to monitor and regulate the grocery sector under the Grocery Industry Competition Act 2023.
Regulatory projects
This section contains all current and closed Commission regulatory projects. This includes determinations, reports, inquiries, studies and disclosures relating to telecommunications, electricity lines, gas pipelines, airports and dairy.
Telecommunications
We work to ensure fixed-line (broadband) and mobile markets are competitive through regulation of wholesale telecommunication services and our monitoring of how the retail market is performing.
Electricity lines
The electricity lines industry in New Zealand is regulated by the Commerce Commission.
Fibre
The Commerce Commission regulates services provided over fibre networks that are critical to social and economic life in New Zealand. We work to incentivise fibre service providers to deliver for the long-term interests of end-users.
Fuel
The Commerce Commission has a role in regulating the fuel industry under the Fuel Industry Act 2020.
Gas pipelines
The gas pipelines industry in New Zealand is regulated by the Commerce Commission
Airports
Auckland, Wellington and Christchurch international airports are our gateways to the world. Together they host nearly 30 million passengers each year.
Dairy
The dairy industry in New Zealand is regulated by the Commerce Commission.
Input methodologies
Input methodologies are the rules, requirements and processes we must determine for regulated services.
Regulatory inquiries
In markets where there is little or no competition, we may need to regulate the price and quality of goods and services for the benefit of consumers. Part 4 of the Commerce Act sets out the particular goods and services that are subject to regulation and the legislative rules governing that regulation. It also sets out the process for us undertaking inquiries into whether regulation of other goods and services may be needed.
Retail payment system
We are responsible for promoting competition and efficiency within the retail payment system.
Water – Wai
The Government has indicated the Commerce Commission will be the economic regulator for water services under the Government's Local Water Done Well (LWDW) regime. We are drawing on our experience in successfully regulating other sectors and international best practice in water regulation to develop an effective regulatory regime tailored for Aotearoa New Zealand.
