Australian magpies (Gymnorhina tibicen) were introduced in the 1860s and 1870s in Canterbury, Otago, Auckland (Kawau Island), Hawke’s Bay and Wellington. They came from Victoria and Tasmania. These populations expanded slowly, remaining separate for many years. The original Otago population has disappeared altogether, but magpies are now found over most of the country except the most densely forested regions, such as Fiordland, or the most open country, such as Central Otago. Magpies were introduced to control pasture pests, which is why they were protected until 1951.
