New Zealand is situated in the South Pacific Ocean, 6,500 kilometres (4,000 miles) south-southwest of Hawaii and 1,900 kilometres (1,200 miles) to the east of Australia. With a land area of 268,000 square kilometres (103,000 square miles), it is similar in area to Japan or Britain. It is comprised of two main adjacent islands, the North Island and South Island, and a number of small outlying islands. Because these islands are widely dispersed, New Zealand has a relatively large exclusive maritime economic zone of 3.1 million nautical square kilometres.
Over half of New Zealand's total land area is pasture and arable land, and more than a quarter is under forest cover, including 1.8 million hectares of planted production forest. It is predominantly mountainous and hilly, with 13% of the total area consisting of alpine terrain, including many peaks exceeding 3,000 metres (9,800 feet). Lakes and rivers cover 1% of the land. Most of the rivers are swift and seldom navigable, but many are valuable sources of hydro-electric power.
