International Dark Sky Week

International Dark Sky Week

International Dark Sky Week (IDSW), scheduled for April 21–28, 2025, is a global initiative dedicated to raising awareness about light pollution and celebrating the beauty of natural nightscapes. Established in 2003 by high school student Jennifer Barlow, IDSW encourages individuals and communities worldwide to appreciate and protect our starry skies.

New Zealand's Commitment to Dark Skies

New Zealand has demonstrated a strong commitment to preserving its night skies, with several regions achieving certification from DarkSky International. These certified Dark Sky Places offer exceptional stargazing opportunities and play a crucial role in conservation and education.

Certified Dark Sky Places in New Zealand:

  1. Aoraki Mackenzie International Dark Sky Reserve: Established in 2012, this reserve encompasses Aoraki/Mount Cook National Park and the Mackenzie Basin. It's renowned for its exceptionally clear skies and is home to the Mount John Observatory.

  2. Aotea / Great Barrier Island International Dark Sky Sanctuary: Designated in 2017, Great Barrier Island became the first island in the world to receive this status. The island's lack of an electricity supply contributes to its pristine night skies.
