Opening Ceremony and Official Remarks
On 15 Oct 2026 Prime Minister Christopher Luxon officially opened Kowhai Park, the South Island’s largest solar farm, at Christchurch Airport. Mike Fuge, chief executive of Contact Energy, said the project showcases New Zealand’s renewable-energy advantage and gives businesses confidence to electrify operations. Justin Watson, chief executive of Christchurch Airport, highlighted the site as an example of innovative airport-land use and part of a broader vision to create a renewable-energy precinct that will generate long-term regional value. Adam Pegg, chief operating officer for Asia-Pacific at Lightsource bp, described the farm as a milestone for the company’s first completed New Zealand project and a demonstration of what large-scale partnerships can achieve.
Development Timeline and Partnerships
The project originated from a 2021 airport-led plan for a 150 MW solar array. Contact Energy and Lightsource bp were announced as joint-venture partners in 2023 to develop, own, and operate the farm. Construction progressed through 2025, employing 235 workers at peak and involving 66 Canterbury-based businesses. Commissioning began in mid-2026, culminating in the October opening.
Project Scale and Technical Details
- Generation capacity: 150 MW ac (168 MW dc)
- Annual output: 275 GWh, enough for roughly 36 000 New Zealand homes
- Infrastructure: About 300 000 photovoltaic panels covering 230 ha of airport land
- Investment: Approximately NZ$ 273 million
- Power purchase agreements: Christchurch Airport and dairy producer Synlait Milk will source electricity from the farm; Synlait will purchase 25 % of the output for its Dunsandel and Dairyworks facilities.
Renewable-Energy Impact
The farm adds a substantial amount of clean generation to the national grid, reinforcing New Zealand’s already high renewable-energy share. By providing a reliable, locally sourced power supply, the project supports industrial electrification, reduces reliance on imported fuels, and enhances energy-security resilience. Officials anticipate that the precinct model could be replicated at other sites, further expanding the country’s low-carbon capacity.
