In 2025, the average cost of electricity for residential use was around ***** New Zealand cents per kilowatt-hour. This was a slight increase in the cost of electricity reported in the previous year. New Zealand’s electricity consumption While the leading sector to consume electricity in New Zealand is the residential sector, the industrial electricity consumption follows closely. A slight decrease in consumption has been observed in both sectors. Although the main primary energy supply of New Zealand is sourced from oil, the electricity generation of the country has already become much greener. New Zealand uses an increasing share of renewable energy in its electricity sector, with over ***percent of the electricity production generated by renewable energy. Leading energy source: Hydropower In the distribution of energy sources used for electricity production, hydroelectric power plants generated more than half of the country's electricity. The production of electricity from hydropower has been rising significantly, only experiencing a slight decrease in 2024, while the country saw a decline in the use of fossil fuels. The increased use of hydropower can also be linked to climate change. In 2022, New Zealand experienced the warmest and wettest year on record, resulting in high hydrolake inflows.

In 2025, the average cost of electricity for industrial use was around ***** New Zealand cents per kilowatt hour. This was an increase in the electricity cost compared to the previous year.

The Electricity Retailing industry in New Zealand has experienced a challenging five-year period, marked by volatile wholesale markets, relatively flat demand growth and tightening margins. Between 2020-21 and 2022-23, surging wholesale electricity prices created significant cost pressures for retailers, particularly those without generation assets. While retail electricity prices have risen in recent years, they’ve failed to keep pace with earlier wholesale price spikes, leading to a drop in profit margins across the industry. Industry revenue is expected to climb at a modest annualised rate of 2.2% over the five years through 2025-26 to reach $9.8 billion. This includes an anticipated 2.2% rise in 2025-26, driven by stronger demand from households and businesses and modest increases in retail tariffs. Higher billed volumes, supported by recent capacity additions and steady consumption growth, have more than offset the drag from easing wholesale prices. Vertically integrated gentailers like Meridian Energy and Mercury have performed better than standalone retailers. These gentailers have leveraged their renewable generation portfolios to buffer their retail businesses from market volatility, generating strong wholesale returns during periods of tight supply. Both companies have also been early movers in bundling electric vehicle (EV) charging solutions with retail offers, capturing emerging high-margin load segments and strengthening customer loyalty. In contrast, non-gentailers have faced a greater margin squeeze and intensified price-based competition. Regulatory settings have influenced industry dynamics. While distribution and transmission charges remain regulated by the Commerce Commission, the current weighted average cost of capital review has slowed increases in network costs, providing some relief to retailers. However, tighter regulation and the repeal of the low fixed charge tariff regime have shifted pricing dynamics, with retailers adjusting strategies to remain competitive. Looking ahead, industry revenue is forecast to jump at an annualised 2.8% over the five years through 2030-31 to reach $11.2 billion. The stronger outlook reflects rising household and business electricity use as electric vehicles become more common and the population grows, along with modest retail tariff increases to fund network upgrades. Smart meters and enhanced digital platforms will continue to engage customers more deeply in their energy consumption, lifting overall sales. However, with wholesale costs easing and competition intensifying, retailers will need to offer tailored plans, demand response programs and seamless digital experiences to lock in loyalty and boost profitability.

The New Zealand solar energy market, currently experiencing robust growth, is projected to expand significantly over the next decade. With a Compound Annual Growth Rate (CAGR) exceeding 3%, the market's value, estimated at approximately $150 million in 2025 (this is an estimation based on typical market sizes for similar-sized countries with comparable solar adoption rates), is poised for substantial expansion. This growth is driven by several key factors: increasing electricity prices, government incentives promoting renewable energy adoption (including subsidies and feed-in tariffs), a growing awareness of climate change and the desire for energy independence among consumers, and advancements in solar panel technology leading to increased efficiency and affordability. The residential sector is expected to be a major contributor to market growth, fueled by homeowners' increasing adoption of rooftop solar systems for both cost savings and environmental reasons. However, the commercial and industrial (C&I) sector also presents a substantial opportunity, with businesses increasingly seeking to reduce their carbon footprint and operational costs through solar installations. The utility-scale sector, although currently smaller, holds significant long-term potential, particularly as New Zealand strives to achieve its renewable energy targets. While challenges remain, including land availability for large-scale projects and potential grid integration issues, the overall outlook for the New Zealand solar energy market is exceptionally positive. Growth in the New Zealand solar market is anticipated to be uneven across regions, with urban areas likely witnessing faster adoption rates than rural areas due to higher electricity consumption and easier access to installation services. Competition among established players like Meridian Energy, JinkoSolar, JA Solar, and emerging companies is likely to intensify, leading to further price reductions and increased innovation. The market is segmented by end-user type (residential, C&I, utility), allowing for tailored strategies catering to the unique needs of each sector. Future growth will depend on continued government support, further technological advancements, and effective public awareness campaigns to address any remaining consumer hesitancy. Further research into specific regional performance and detailed regulatory landscape analysis will provide more granular insights into the future trajectory of this dynamic and rapidly expanding market. Recent developments include: May 2022: Auckland-based renewables developer Far North Solar Farm (FNSF) announced its partnership with German investment manager and asset development company Aquila Capital to develop an estimated USD 1 billion suite of large-scale solar PV projects across New Zealand's North and South islands. The company expected to commence construction on a 1 GW portfolio of large-scale solar PV projects across the North and South islands., April 2022: Contact Energy and Lightsource BP joined a partnership to co-develop grid-scale solar farms in New Zealand. Kwhai Park is expected to be the first of several planned solar farms for the Lightsource BP and Contact Energy alliance in New Zealand. The park's first phase was expected to consist of a solar farm that will span around 300 hectares of land just behind the airport's runways.. Notable trends are: Utility Sector to Witness a Significant Growth.
