Invasive Species In New Zealand
A number of introduced species, some of which have become invasive species, have been added to New Zealand's native flora and fauna. Both deliberate and accidental introductions have been made from the time of the first human settlement, with several waves of Polynesian people at some time before the year 1300, followed by Europeans after 1769. Almost without exception, the introduced species have been detrimental to the native flora and fauna but some, such as sheep and cows and the clover upon which they feed, now form a large part of the economy of New Zealand. Biosecurity New Zealand maintain registers, lists and indexes of species that are invasive, potentially invasive, or a threat to agriculture or biodiversity.
A small number of invasive species of New Zealand origin are creating problems in other countries.

“The frequency of personal questions grows in direct proportion to your increasing girth. . . .

—Jean Marzollo (20th century)
“Not only does every animal live at the expense of some other animal or plant, but the very plants are at war.... The individuals of a species are like the crew of a foundered ship, and none but good swimmers have a chance of reaching the land.”
—Thomas Henry Huxley (1825–95)
“Teasing is universal. Anthropologists have found the same fundamental patterns of teasing among New Zealand aborigine children and inner-city kids on the playgrounds of Philadelphia.”
