The Department of Conservation is the public service department of New Zealand charged with the conservation of New Zealand's natural and historical heritage.

The national parks of New Zealand are protected natural areas administered by the Department of Conservation (DOC). The first national parks established in the country were all focused on mountain scenery. Since the 1980s the focus has been on developing a more diverse representation of New Zealand landscapes. The parks are all culturally significant and many also contain historic features. Tongariro National Park is one of the World Heritage Sites that are of both cultural and natural significance, while four of the South Island national parks form Te Wahipounamu, another World Heritage Site. There are currently 13 national parks; a 14th, Te Urewera National Park, was disestablished in 2014.
