The South Island or Te Waipounamu is the larger of the two major islands of New Zealand, 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) and is influenced by a temperate climate.
As it has a 33% larger landmass than the North Island it is often known as the “mainland”; however, only 23% of New Zealand’s 4.5 million inhabitants live in the South Island. In the early stages of European (P?keh?) settlement of the country, the South Island had the majority of the European population and wealth due to the 1860s gold rushes. The North Island population overtook the South in the early 20th century, with 56% of the population living in the North in 1911, and the drift north of people and businesses continued throughout the century.
