The North Island Robin (Petroica longipes) is a species of Australasian robin endemic to the North Island of New Zealand. It was once considered a subspecies of the New Zealand Robin (Petroica australis) of South and Stewart Islands, but mitochondrial DNA sequences have shown that the two lineages split prior to the Pleistocene and supported the split into two species. Zealandia, formerly known as the Karori Wildlife Sanctuary, is a protected natural area in Wellington, New Zealand, where the biodiversity of 225 ha of forest is being restored.
The North Island Brown Kiwi, Apteryx mantelli, Apteryx australis or Apteryx bulleri before 2000 (and still in some sources), is a species of kiwi that is widespread in the northern two-thirds of the North Island of New Zealand and, with about 35000 remaining, is the most common kiwi. museum specimen;
The Short-tailed Albatross or Steller's Albatross, Phoebastria albatrus, is a large rare seabird from the North Pacific. Although related to the other North Pacific albatrosses, it also exhibits behavioural and morphological links to the albatrosses of the Southern Ocean. It was described by the German naturalist Peter Simon Pallas from skins collected by the Georg Wilhelm Steller (after whom its other common name is derived). Once common, it was brought to the edge of extinction by the trade in feathers, but with protection has recently made a recovery.
