The Otago Museum is located in the city centre of Dunedin, New Zealand. It is adjacent to the University of Otago campus in Dunedin North, 1,500 metres northeast of the city centre. It is one of the city's leading attractions, with over 480,000 visitors each year, and has one of the largest collections in New Zealand. Natural science specimens and humanities artefacts from Otago, New Zealand and the world form the basis for long-term gallery displays, while exhibitions on a wide range of subjects change regularly. An interactive science centre within the Museum includes a large, immersive tropical butterfly rainforest environment.
