Tongariro National Park
This 26.4 km2 area was generally considered to be too small to establish a national park after the model of Yellowstone National Park in Wyoming, United States, and so further areas were acquired. When the New Zealand Parliament passed the Tongariro National Park Act in October 1894, the park covered an area of about 252.13 km2, but it took until 1907 to acquire the land. When the Act was renewed in 1922, the park area was extended to 586.8 km2. Further extensions, especially Pihanga Scenic Reserve in 1975, enlarged the park to its current size of 786.23 km2. The last modification to the Act was passed in 1980. Tongariro National Park has been under the control of the New Zealand Department of Conservation since the creation of the department in 1987.
