Operators seek cooling solutions after Christchurch stadium heat reaches 32.5C

Operators of Christchurch’s One New Zealand Stadium are investigating ways to mitigate heat after temperatures in parts of the venue reached 32.5C during the NPC final on Monday. Venues Ōtautahi chief executive Caroline Harvie-Teare described the conditions as "sauna-like" and acknowledged that more work is required to ensure guest comfort.

During the match between Canterbury and Northland, the average temperature inside the stadium was recorded at 28.6C. The highest temperatures were recorded on the east side in direct sunlight, while the south and west stands remained cooler.

To manage the heat, 4,000 bottles of water were sold and additional free water stations were provided, which saw the longest queues at halftime. Players also received hydration breaks during the match, which was a first for an NPC final.

Harvie-Teare stated that while the stadium's indoor spaces are air conditioned, the seating bowl lacks a cooling system. She noted that the roof allows 90% of the sun's UV rays to pass through to support grass growth.

Future mitigation strategies being discussed include working with the council and engineers to find permanent solutions, such as adding more louvres or opening building corners. The venue may also consider scheduling events to avoid the hottest times of the day.
