Tāhuna Glenorchy Dark Sky Sanctuary
Tāhuna Glenorchy Dark Sky Sanctuary
The Tāhuna Glenorchy Dark Sky Sanctuary is a protected area in New Zealand’s South Island, in the Queenstown-Lakes District. It covers about 2,150 square kilometres around the head of Lake Wakatipu and includes a large part of Mount Aspiring National Park.
The sanctuary starts at Bennett’s Bluff on the road between Queenstown and Glenorchy and reaches to the northern edge of Mount Aspiring National Park. About 75% of the area lies within Te Wāhipounamu World Heritage Area. It also contains parts of popular hiking routes such as the Greenstone-Caples, Routeburn, and Rees–Dart tracks.
Dark Sky International certified Tāhuna Glenorchy as a Dark Sky Sanctuary on 3 February 2025, making it the 23rd sanctuary worldwide. The towns of Glenorchy and Kinloch are not included in the sanctuary. As of August 2025, there are plans to seek certification for the townships as a Dark Sky Community.
A dark sky sanctuary is land designated to protect exceptionally clear, star-filled skies for science, nature, education, cultural heritage, and public enjoyment.
The sanctuary was created by the Glenorchy Heritage and Museum Group, led by chairperson Leslie Van Gelder. The team spent five years preparing the designation. They report a very dark night sky: approximately 21.61 magnitudes per square arcsecond (Bortle 2), with no visible light domes because mountains shield Queenstown’s light from the area.
Located around 45°S, the sanctuary offers a rare view where the Aurora Australis and the core of the Milky Way can be seen. Only about 10,000 people live in this latitude band worldwide.
The group worked with the Department of Conservation, with hut wardens helping to measure night-sky brightness. Representatives of the Kāi Tahu iwi contributed their understanding of how Māori view the stars. The sanctuary supports educational activities and annual Matariki celebrations, the Māori New Year.
The name Tāhuna Glenorchy reflects the Māori word tāhuna, meaning sandy shore or beach, and also refers to the land where Queenstown sits.
Before the official designation, the Otago-based Winterstellar organization awarded Tāhuna Glenorchy its first recognition in December 2024.
