Argentine Ants in New Zealand

The World Conservation Union lists the Argentine ant as one of the world´s worst invasive species. The Argentine ant originally established in Auckland in 1990, and is now a problem in an increasing number of towns and cities throughout New Zealand. From one urban area to another, Argentine ants hitch rides in freight, potted plants, rubbish, vehicles and other such goods.

However, many natural areas are also at risk, and an infestation has been found on Tiritiri Matangi Island in the Hauraki Gulf, a highly valued open sanctuary and scientific reserve.
