Native birds have always been in their current location. Introduced birds have been brought in from elsewhere - either deliberately or accidentally.
Hedgehogs were introduced to New Zealand in 1885.
No. Weasels are neither native to Australia, nor have they been introduced to Australia. Weasels have been introduced to New Zealand, but New Zealand is not part of Australia. It is a totally separate country.
Myna birds are native to southern and eastern Asia, but have been introduced to Australia, North America, New Zealand, and South Africa by humans, where they are often regarded as invasive species.
Two species of Wallabies. The Parma - on Kawau island - apparently introduced by Gov Grey; and the Brush-tailed (?) Wallaby, in the Waimate area of the South island. The Red-necked wallaby has also been introduced, and has become a major pest. And of course the Common Brush-tailed Possum, which having turned omnivore is a danger to the native birds.
Almost everything eaten in New Zealand was introduced from other countries with the exception of fish. Most of the native flora and fauna is protected or inedible.
It is not known when kiwi came to New Zealand. Fossil evidence indicates that kiwi have been in New Zealand since long before Man arrived.
Brushtail possums are found in Australia. They have also been introduced to New Zealand.
If nobody had come here it would have remained an unspoilt, densely forested country. Possibly the Moa would still be alive and many other birds etc that have been killed by the rats that were introduced.
Kookaburras have been introduced to both Tasmania(Australia's island state to the south) and the separate country of New Zealand (to the southeast).
It depends on the country from which this question originates. Wallabies are native to Australia alone, but have been introduced to numerous other countries, including New Zealand.
Introduced species and habitat loss are the primary causes of extinction of native species in New Zealand. Introduced species such as feral cats, foxes, rats and stoats have decimated some native populations. Even the brushtail possum, rainbow lorikeets, black swan and cockatoos which have been introduced from Australia, threaten the habitat of native New Zealand species.
