The national parks of New Zealand are 13 protected areas administered by the Department of Conservation "for the benefit, use, and enjoyment of the public". They are popular tourist destinations, with three-tenths of overseas tourists visiting at least one national park during their stay in New Zealand. Although the national parks contain some of New Zealand's most beautiful scenery, the first few established 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; many also contain historic features.
