Qualla: Wai-iti Dark Sky Park

Wai-iti Dark Sky Park: Introduction

Mon, 09 Mar 2026 00:00:00 GMT

On the best nights at Wai-iti, the sky scores a 1 on the Bortle scale. That is as dark as it gets anywhere on Earth: no light domes on the horizon, no skyglow washing out the fainter stars, the zodiacal light bright enough to cast shadows.

Wai-iti Dark Sky Park sits on 135 hectares of Tasman District Council land near the township of Wakefield, about 33 kilometres from Nelson on New Zealand's South Island. It includes Tunnicliff Forest and the Wai-iti Recreation Reserve, and in July 2020 it became the first place in New Zealand to receive International Dark Sky Park accreditation from DarkSky International.

Stand in Wai-iti on a clear winter night and the Southern Hemisphere sky puts on a display that has no equivalent in the north. The Magellanic Clouds, two satellite galaxies of the Milky Way, hang like detached fragments of the galactic band. The Southern Cross wheels through its...
