The Southern Alps run along much of the South Island, with broad plains to the east and a wetter, more dissected western side. The North Island has a different outline and includes a central volcanic region. Cook Strait separates the two main islands.

Mountain scenery can resemble Chile or parts of Europe. Fjords alone do not establish New Zealand. At regional scale, the island outlines and the position of mountains relative to the coasts are stronger clues.
