Tiwai Point lies at the entrance to Bluff Harbour on the southern coast of the South Island of New Zealand. A spit which extends from the western end of the Awarua Plain, it lies between Awarua Bay to the north and Foveaux Strait to the south. It is known for the Tiwai Point Aluminium Smelter, one of the largest industrial facilities in New Zealand.[1]
Demographics
editTiwai Point is part of the Woodend-Greenhills statistical area.[2]
Tiwai Rocks Important Bird Area
editThe rocks at the tip of Tiwai Point have been identified as an Important Bird Area by BirdLife International because they are home to a breeding colony of Foveaux shags.[3]
Foveaux looper moth
editTiwai Point is one of the two remaining locations where the critically endangered Foveaux looper moth lives.[4] A. frivola is at high risk of extinction, and has already disappeared from one of its three known localities.[5] Its main population exists on an area at Tiwai Point of less than 25 m2 of coastal vegetation.
Causeway accident
editIn 1980, a vehicle with 10 people failed to take a turn on the Tiwai Point causeway, crashing through a barrier and falling into the water. Seven people died, including five who were never recovered.[6]
