Invercargill (/ˌɪnvərˈkɑːrɡɪl/ IN-vər-KAR-ghil, Māori: Waihōpai) is the southernmost and westernmost city in New Zealand, and one of the southernmost cities in the world. It is the commercial centre of the Southland region. The city lies in the heart of the wide expanse of the Southland Plains to the east of the Ōreti or New River some 18 km (11 miles) north of Bluff, which is the southernmost town in the South Island. It sits amid rich farmland that is bordered by large areas of conservation land and marine reserves, including Fiordland National Park covering the south-west corner of the South Island and the Catlins coastal region.
