World-leading electricity market
In New Zealand most electricity is generated through renewable energy sources, such as hydropower, geothermal power and wind energy. In 2022, 87% of electricity is generated from renewable sources1, making New Zealand one of the countries with the lowest carbon dioxide emissions from electricity generation.
Over the past 20 years, Aotearoa’s electricity market has been praised domestically and internationally – it's considered world-leading. During this time, our work embedding a market-based regime has delivered significant benefits that is the envy of other jurisdictions.
The International Energy Agency said in its 2023 review of New Zealand’s energy policies: "New Zealand has a diversified energy mix, with significant production of both hydropower and geothermal. As the country embarks on an ambitious energy transition, it has many natural advantages, including an enviable renewable resource base. The key challenge will be to decarbonise end-use sectors through clean power and support investments in new technologies to achieve deeper emissions cuts across all sectors in the most economically efficient way. "
New Zealand also regularly features in the top 10 of the World Energy Council’s energy ‘trilemma’ index. This reflects Aotearoa's strong balance of energy security, energy equity and environmental sustainability.
