Dark Sky Reserves in New Zealand. When you read or hear about New Zealand having a “Dark Sky Reserve” why should you care? Well, dark skies at night make for exceptional stargazing. Dark skies are usually found in places with less light pollution, so an area in a Dark Sky Reserve restricts the amount of artificial light pollution retaining the quality of the skies.
