Lake Marian in Fiordland National Park.

Lake Taupo

In New Zealand there are 3,820 lakes with a surface area larger than one hectare. The lakes are of varying types and origins. Many of the lakes in the central North Island area are volcanic crater lakes, while the majority of the lakes near the Southern Alps were carved by glaciers. Hydroelectric reservoirs are common in South Canterbury, Central Otago and along the Waikato River.
