|The South Island is the larger of the two major islands of New Zealand in surface area, the other being the smaller but more populous North Island. It is bordered to the north by Cook Strait, to the west by the Tasman Sea, and to the south and east by the Pacific Ocean. The South Island covers 150,437 square kilometres (58,084 sq mi) making it the world’s 12th-largest island. At low altitude, it has an oceanic climate.
The South Island is shaped by the Southern Alps which run along it from north to south. They include New Zealand’s highest peak, Aoraki / Mount Cook at 3,724 metres (12,218 ft). The high Kaikoura Ranges lie to the northeast. The east side of the island is home to the Canterbury Plains while the West Coast is famous for its rough coastlines such as Fiordland, a very high proportion of native bush and national parks, and the Fox and Franz Josef Glaciers. The main centres are Christchurch and Dunedin. The economy relies on agriculture and fishing, tourism, and general manufacturing and services.
