Tiwai Point Aluminium Smelter, aluminium smelter in New Zealand
Tiwai Point Aluminium Smelter is New Zealand's only aluminium production facility, located on the coast near Bluff in the Southland region. The plant imports alumina from Australia and converts it into pure metal using the Hall-Héroult process, with almost all production exported internationally.
The smelter was built in the early 1970s after the Manapouri hydroelectric power station was constructed to supply its energy needs. Since opening, it has established itself as a major production site and has played a significant role in the country's industrial development.
The smelter has been a major employer in the Southland region since the 1970s, shaping the local community and economy. Workers take pride in producing high-quality metal shipped worldwide, making it central to the area's identity and daily life.
The site sits in a quiet, open area with views of the water and is easily accessible from nearby Invercargill. Visitors should know the plant is an active industrial facility and may have restricted access, so it's best to check ahead about visiting options.
Before industrial use, the site was culturally significant to Māori people, who made tools from argillite stone starting around 1300. Archaeologists have found remnants of these ancient tools, revealing a long history of human use before modern manufacturing arrived.
