Tāhuna Glenorchy Dark Sky Sanctuary (opens in a new tab)
A subgroup of the Glenorchy Heritage and Museum Group, certified by DarkSky International in February this year, covering about 2,150 square kilometres at the head of Lake Whakatipu.
Keeping the certification means measuring how dark the sky actually is. Meter readings are taken at fixed sites, four compass points at a time, written down by hand, and typed up later into a spreadsheet that lives with one person. It takes two people every time.
