Bluff- The Artificial Island

The port facilities are the southernmost in the South Island, and include the country's southernmost commercial deep water port. The port operates under the commercial name of South Port NZ from a 40-hectare (99-acre) artificial island, Island Harbour, and includes a container terminal. Island Harbour was constructed over the course of the 1950s, and was officially opened in December 1960. A major cargo from the port is alumina from the Tiwai Point Aluminium Smelter, which sits on Tiwai Point, the low-lying eastern shore of the harbour's mouth, directly opposite Island Harbour.
