We all know how magnificent the natural wonders of New Zealand are, but it also takes the title of the largest Gold Tier Dark Sky Reserve in the world. The reserve covers 1,600 square miles of the center of South Island and takes in the Aoraki National Park and part of the Mackenzie Basin. Aoraki is the Maori name for Mount Cook - the highest mountain in New Zealand. Lake Tekapo is one of the country's favourite and best spots for stargazers.
