What Is a Dark Sky Reserve – And Why Does It Matter?

At Dark Sky Project, we’re on a mission to connect manuhiri (visitors) with the cosmos through unforgettable stargazing experiences in one of the best places on Earth to see the night sky. But what exactly makes our location so special? The answer lies in our surroundings – we’re located within an International Dark Sky Reserve.

So, what is a Dark Sky Reserve?

An International Dark Sky Reserve is a designated area recognised for its exceptional quality of starry nights and a commitment to protecting the nocturnal environment. These reserves are certified by the International Dark-Sky Association (IDA) and are among the best places in the world to witness the night sky in its most pristine state.

There are only a handful of these reserves around the globe, and the Aoraki Mackenzie region – home to Dark Sky Project – is one of them.

Aoraki Mackenzie: A Light in the Darkness

Our reserve was established in 2012 and is the largest Dark Sky Reserve in the Southern Hemisphere, and the second largest in the world. It spans over 4,300 square kilometres across Aoraki/Mount Cook National Park and the Mackenzie Basin.

The area is shielded from light pollution thanks to ongoing efforts by the local community, regional councils, and passionate advocates of dark sky conservation. These efforts mean that on a clear night, you can see celestial wonders that have inspired storytelling, science, and culture for thousands of years.

Why Are Dark Sky Reserves Important?

Light pollution doesn’t just hide the stars. It affects ecosystems, wildlife, and even human health. By protecting our night skies, we’re also protecting our natural environment and cultural heritage.

For Ngāi Tahu, the night sky is deeply connected to ancestral knowledge and navigation. At Dark Sky Project, we honour these traditions and blend tātai aroraki (Māori astronomy) with cutting-edge science to share a uniquely Aotearoa perspective of the universe.

Experience the Magic for Yourself

Whether you’re gazing at the Milky Way from the summit of Mount John or discovering the stories behind the stars inside our purpose-built observatory, visiting a Dark Sky Reserve is a profound experience. It's a reminder of how vast our universe is – and how important it is to protect the darkness.

Join us under the stars and see what makes our part of the world truly out of this world.
