Established in 1986 to service the Rio Tinto - NZAS plant at Tiwai Point, this location is the sales office and warehouse for the South Island region of New Zealand. 

The Invercargill plant is equipped to manufacture vacuum formed products, soft products, and a range of refractory items specific to NZAS.
