The Chatham Islands are an archipelago in the Pacific Ocean about 800 km (430 nmi) east of New Zealand's South Island. They are administered as part of New Zealand. The archipelago consists of about 10 islands within an approximate 60 km (30 nmi) radius, the largest of which are Chatham Island and Pitt Island (Rangiauria). They include New Zealand's easternmost point, the Forty-Fours. Some of the islands, formerly cleared for farming, are now preserved as nature reserves to conserve some of the unique flora and fauna.
Rails are a large, cosmopolitan family of small- to medium-sized terrestrial and/or semi-amphibious birds. The family exhibits considerable diversity in its forms, and includes such ubiquitous species as the crakes, coots, and gallinule; other rail species are extremely rare or endangered. Many are associated with wetland habitats, some being semi-aquatic like waterfowl, but many more are wading birds or shorebirds. The ideal rail habitats are marsh areas, including rice paddies, and flooded fields or open forest. They are especially fond of dense vegetation for nesting. The rail family is found in every terrestrial habitat with the exception of dry desert, polar or freezing regions, and alpine areas. Members of Rallidae occur on every continent except Antarctica. Numerous unique island species are known.
Territorial authorities are the second tier of local government in New Zealand, below regional councils. There are 67 territorial authorities: 13 city councils, 53 district councils and the Chatham Islands Council. District councils serve a combination of rural and urban communities, while city councils administer the larger urban areas. Five territorial authorities also perform the functions of a regional council and thus are unitary authorities. The Chatham Islands Council is a sui generis territorial authority that is similar to a unitary authority.
The Moriori are the indigenous Polynesian people of the Chatham Islands, New Zealand. Moriori originated from Māori settlers from the New Zealand mainland around 1500 CE. This was near the time of the shift from the archaic to classic Māori culture on the main islands of New Zealand. Oral tradition records multiple waves of migration to the Chatham Islands, starting in the 16th century. Over several centuries these settlers' culture diverged from mainland Māori, developing a distinctive language, mythology, artistic expression and way of life. Currently there are around 700 people who identify as Moriori, most of whom no longer live on the Chatham Islands. During the late 19th century some prominent anthropologists mistakenly proposed that Moriori were pre-Māori settlers of mainland New Zealand, and possibly Melanesian in origin.
Chatham Island is by far the largest island of the Chatham Islands group, in the south Pacific Ocean off the eastern coast of New Zealand's South Island. It is said to be "halfway between the equator and the pole, and right on the International Date Line", though the point in fact lies ca. 173 miles WSW of the island's westernmost point. The island is called Rekohu in Moriori, and Wharekauri in Māori.
The New Zealand bellbird, also known by its Māori names korimako, makomako, and kōmako, is a passerine bird endemic to New Zealand. It has greenish colouration and is the only living member of the genus Anthornis. The bellbird forms a significant component of the famed New Zealand dawn chorus of bird song that was much noted by early European settlers. The explorer Captain Cook wrote of its song "it seemed to be like small bells most exquisitely tuned". The species is common across much of New Zealand and its offshore islands as well as the Auckland Islands.
Corokia is a genus in the Argophyllaceae family. The genus was first described in 1839. It comprising six species native to New Zealand, Australia and Rapa Iti. Corokia species are shrubs or small trees with zigzagging (divaricating) branches. In fact, Corokia cotoneaster is commonly known as wire-netting bush. The stems of the shrubs are dark when mature, covered with downy or silky hairs (tomentum) when young. In spring, they produce clusters of small, star-shaped yellow blossoms. Berries are red or yellow. The shrubs prefer forests and rocky areas, sun or light shade, reasonably well drained soil, and moderate watering.
Palaeeudyptes is an extinct genus of large penguins, currently containing four accepted species. They were probably larger than almost all living penguins, with the smaller species being about the size of an emperor penguin, and the largest species, Palaeeudyptes klekowskii, having stood up to 2 meters (6.6 ft) tall and weighed up to 116 kg (256 lb).
The tomtit is a small passerine bird in the family Petroicidae, the Australasian robins. It is endemic to the islands of New Zealand, ranging across the main islands as well as several of the outlying islands. In the Māori language, the North Island tomtit is known as miromiro and the South Island tomtit is known as ngirungiru. This bird has several other Māori and English names as well. There are several subspecies showing considerable variation in plumage and size. The species is not threatened and has adapted to the changes made to New Zealand's biodiversity.
The austral snipes, also known as the New Zealand snipes or tutukiwi, are a genus, Coenocorypha, of tiny birds in the sandpiper family, which are now only found on New Zealand's outlying islands. There are currently three living species and six known extinct species, with the Subantarctic snipe having three subspecies, including the Campbell Island snipe discovered as recently as 1997. The genus was once distributed from Fiji, New Caledonia and Norfolk Island, across New Zealand and southwards into New Zealand's subantarctic islands, but predation by introduced species, especially rats, has drastically reduced their range.
Novoplectron is a monotypic genus of cave wētā in the family Rhaphidophoridae, endemic to the Chatham Islands. Cave wētā are nocturnal, wingless crickets that occupy humid habitats. Novoplectron wētā generally live under stones and in burrows of seabirds, such as broad-billed prions, mutton birds and storm petrels.
The Chatham pigeon, also called the Chatham Island pigeon or parea, is a bird endemic to the Chatham Islands in New Zealand. Growing to 800g in weight and 55 cm in length, the Chatham Island pigeon is closely related to the kererū or New Zealand pigeon, the only other species in the genus Hemiphaga.
Brachyglottis huntii, commonly called rautini or Chatham Island Christmas tree, is a species of flowering plant in the family Asteraceae. It is found only on the Chatham Islands in New Zealand.
The Chatham shag, also known as the Chatham Island shag, is a species of bird in the cormorant and shag family, Phalacrocoracidae. It is endemic to the Chatham Islands of New Zealand. For a long time the species was placed in the genus Phalacrocorax; today it is mostly placed with the other blue-eyed shags of New Zealand and Antarctica in the genus Leucocarbo. Its closest relative is the Otago shag of South Island.
The New Zealand fantail is a small insectivorous bird, the only species of fantail in New Zealand. It has four subspecies: R. f. fuliginosa in the South Island, R. f. placabilis in the North Island, R. f. penita in the Chatham Islands, and the now-extinct R. f. cervina formerly on Lord Howe Island. It is also known by its Māori names, pīwakawaka, tīwakawaka or piwaiwaka, and the Chatham Island subspecies by the Moriori name tchitake; the common pied morph is also known as pied fantail, and the uncommon dark morph is also known as black fantail. The species has been considered by many to be conspecific as the grey fantail of Australia and New Caledonia; however, due to significant differences in its calls, many authorities now treat it as a separate species.
Cominella adspersa, the speckled whelk or kawari in Maori, is a predatory sea snail, a marine gastropod mollusc in the family Cominellidae.
Leptinella is a genus of alpine flowering plant in the family Asteraceae, comprising 33 species, distributed in New Guinea, Australia, New Zealand, South Africa, and South America. Many of the species are endemic to New Zealand.
Dracophyllum arboreum, commonly known as Chatham Island grass tree and tarahinau (Moriori), is a species of tree in the heath family Ericaceae. Endemic to the Chatham Islands of New Zealand, it reaches a height of 18 m (60 ft) and has leaves that differ between the juvenile and adult forms.
