This is a list of New Zealand species extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years Before Present (about 9700 BCE)^[a] and continues to the present day.^[1] This epoch equates with the latter third of the Haweran Stage of the Wanganui epoch in the New Zealand geologic time scale.

The North Island and South Island are the two largest islands of New Zealand. Stewart Island is the largest of the smaller islands. New Zealand proper also includes outlying islands such as the Chatham Islands, Kermadec Islands, and New Zealand Subantarctic Islands. Only New Zealand proper is represented on this list, not the Realm of New Zealand. For extinctions in the Cook Islands, Niue, or Tokelau, see the List of Oceanian animals extinct in the Holocene.

The islands of East Polynesia (including New Zealand, Hawaii, and Easter Island) were among the last habitable places on Earth colonised by humans.^[2][3] The first settlers of New Zealand migrated from Polynesia and became the Māori people.^[4] According to archeological and genetic research, the ancestors of the Māori arrived in New Zealand no earlier than about 1280 CE, with at least the main settlement period between about 1320 and 1350,^[5][4] consistent with evidence based on whakapapa (genealogical traditions).^[6][7] No credible evidence exists of pre-Māori settlement of New Zealand.^[4] In 1642, the Dutch navigator Abel Tasman became the first European explorer known to visit New Zealand.^[8] In 1769, British explorer James Cook became the first European to map New Zealand and communicate with the Māori.^[9][10] From the late 18th century, the country was regularly visited by explorers and other sailors, missionaries, traders and adventurers. In 1840, the Treaty of Waitangi annexed New Zealand into the British Empire.^[11][12][13] As a result of the influx of settlers, the population of Pākehā (European New Zealanders) grew explosively from fewer than 1,000 in 1831 to 500,000 by 1881.^[14]

Numerous species have disappeared from New Zealand as part of the ongoing Holocene extinction, driven by human activity. Human contact, first by Polynesians and later by Europeans, had a significant impact on the environment. The arrival of the Māori resulted in animal extinctions due to deforestation^[3] and hunting.^[15] The Māori also brought two species of land mammals, Polynesian rats (Rattus exulans) and kurī, a breed of domestic dog (Canis lupus familiaris).^[3][16] In pre-human times, bats were the only land mammals found in New Zealand.^[17] Polynesian rats definitely contributed to extinctions,^[3] and kurī might have contributed as well.^[18][19] Like the Māori settlers centuries earlier, the European settlers hunted native animals and engaged in habitat destruction. They also introduced numerous invasive species.^[20] A few examples are black rats (Rattus rattus) and brown rats (Rattus norvegicus),^[21] domestic cats (Felis catus),^[22] stoats (Mustela erminea),^[23] and common brushtail possums (Trichosurus vulpecula).^[24]

This list of extinct species only includes the indigenous biota of New Zealand, not domestic animals like the kurī.

New Zealand greater short-tailed bat	Mystacina robusta	North and South Island	Widespread on both islands in pre-Māori times, as evidenced by subfossil remains, this species was restricted to Taukihepa / Big South Cape Island and other islands off Stewart Island at the time of European arrival. The reason for extinction in the mainland was likely predation by introduced Polynesian rats. Listed as "Critically Endangered (Possibly Extinct)" by the IUCN as individuals have not been sighted since 1967, following the introduction of black rats to Taukihepa / Big South Cape Island. However, the species might still persist on Big South Cape, Putauhinu and other islands off Stewart.[25]

New Zealand sea lion	Phocarctos hookeri 'NZ'	Coastal North and South Island	Distinct lineage of the New Zealand sea lion once found all over the North and South Islands, as evidenced by ancient DNA studies on subfossil remains dating to just before 1280 CE.[26] It was hunted to extinction by the Maori within a few centuries. Afterwards, the subantarctic lineage of the New Zealand sea lion colonised Stewart Island and the southeastern coast of the South Island from the Auckland and Campbell Islands.[27]
Chatham Islands sea lion	Phocarctos hookeri 'Chathams'	Chatham Islands	Distinct lineage that became extinct due to overhunting within two centuries of Moriori settlement, in 1450-1650 CE.[28]

North Island giant moa	Dinornis novaezealandiae	North Island[29] and Great Barrier Island[30]	Most recent bones in the Ruahine Range were dated to 1286–1390 CE.[31] The main cause of extinction was overhunting. Moa chicks may have also been eaten by Polynesian dogs.[30]
South Island giant moa	Dinornis robustus	South Island, Stewart Island,[29] and D'Urville Island[32]	Most recent bones in Tumbledown Bay, Canterbury were dated to 1451–1952 CE (1558–1728 CE maximum likelihood), making this a contender for last surviving moa species.[33] They were hunted, and their bones are widespread in Māori middens, shaped into tools and ornaments. Estimates of moa remains in 1,200 open ovens and middens surveyed in the vicinity of the Waitaki River mouth during the 1930s range from 29,000 to 90,000. Moa chicks may have been eaten by Polynesian dogs. Burning of the giant moa's dry forest and shrubland habitat also likely reduced their numbers.[32]

Bush moa	Anomalopteryx didiformis	North Island, South Island, and Stewart Island[29]	Most recent bones in Echo Valley, Fiordland were dated to 1310-1420 CE.[33] The main cause of extinction was overhunting. Moa chicks may have been eaten by Polynesian dogs.[34]
Eastern moa	Emeus crassus	South Island[29]	Most recent eggshell fragments at Wairau Bar were dated to 1320–1350 CE.[35] The main cause of extinction was overhunting. Remains are widespread in middens, along with tools used to cut up carcasses and to work bones into tools. Middens in the Marlborough district contained remains of more than 4,000 individuals and large numbers of eggs. Eastern moa was the second most abundant species recorded after the broad-billed moa. Moa chicks may have also been eaten by Polynesian dogs. Burning of the eastern moa's forest and shrubland habitat is also likely to have reduced its numbers.[36]
Broad-billed moa	Euryapteryx curtus	North, South,[29][b] Stewart, and Great Barrier Island[37]	Most recent bones in Ototara, North Otago were dated to 1464–1637 CE, making this a contender for last surviving moa species.[33] The main cause of extinction was overhunting. Remains are widespread in middens, along with specialised tools used to cut up carcasses and to work bones into tools. Moa chicks may have also been eaten by Polynesian dogs. Burning of the broad-billed moa's forest and shrubland habitat is also likely to have reduced its numbers.[37]
Heavy-footed moa	Pachyornis elephantopus	South Island and Stewart Island[29]	Most recent bones in Kawarau Valley, Central Otago were dated to 1294–1438 CE.[33] The main cause of extinction was overhunting. Moa chicks may also have been eaten by Polynesian dogs. Burning of eastern dryland forests and shrublands is also likely to have reduced the extent of suitable habitat.[38]
Mantell's moa	Pachyornis geranoides	North Island[29]	Most recent remains were dated to 1278–1415 CE.[39] The main cause of extinction was overhunting. Moa chicks may also have been eaten by Polynesian dogs.[40]
Crested moa	Pachyornis australis	South Island[29]	Subalpine restricted species believed extinct during the Pleistocene-Holocene extinction around 10,000 years ago, until a partial skeleton from the Bulmer Cavern of Mount Owen was dated to 1396–1442 CE.[33] The main cause of extinction was probably overhunting. Crested moa chicks may also have been eaten by Polynesian dogs.[41]

Chatham duck	Anas chathamica	Chatham Islands[29]	Remains dated to 448–657 CE, but believed to have survived until Polynesian arrival c. 1350.[39] The species likely became extinct through overhunting, as it was large and flightless.[47]
New Zealand musk duck	Biziura delautouri	North Island and South Island[29]	One bone was found in a food midden. Hunting is the most likely cause of extinction, which happened before European arrival.[48]
Finsch's duck	Chenonetta finschi	North Island and South Island[49]	Extinct in the 16th century due to hunting and predation by Polynesian rats.[49]
South Island goose	Cnemiornis calcitrans	South Island[29]	Hunted by early Polynesian settlers, their remains are widespread in midden deposits. Overhunting is the most likely cause of extinction.[50] The date of extinction is unknown, but probably happened in the 16th century.[43]
North Island goose	Cnemiornis gracilis	North Island[29]	Remains dated to the first millennium CE,[51] but believed to have survived until Polynesian arrival c. 1280.[39] A possible historical record, describing a rufous flightless goose that was hunted with dogs, was made in 1875. Though the reasons of extinction are unknown, any flightless goose would have been extremely vulnerable to overhunting.[43]
Chatham Islands swan	Cygnus sumnerensis chathamicus	Chatham Islands[43]	Likely hunted to extinction by the Moriori before 1650 CE.[52]
New Zealand swan	Cygnus sumnerensis sumnerensis	South Island[43]	Bones were found in Polynesian middens,[52] and dated to 1059-1401 CE.[39] It was probably driven to extinction through overhunting before 1450 CE. This species was considered once synonymous with the Australian black swan which was later introduced to New Zealand by Europeans, but an ancient DNA study confirmed that they were different species that separated from a common ancestor 1–2 million years ago.[52]
Scarlett's duck	Malacorhynchus scarletti	North Island, South Island, and Chatham Islands[53][29]	Became extinct sometime after Polynesian arrival. It was hunted by the Māori and its nests were possibly susceptible to predation by Polynesian rats.[53]
New Zealand merganser	Mergus australis	Auckland Islands,[29] North Island, South Island, Stewart Island[29][c]	Reduced to the Auckland Islands only by the time of European colonisation, it was last recorded in 1902. Became extinct due to hunting and predation by introduced mammals.[54]
Chatham Island merganser	Mergus milleneri	Chatham Island[55]	Only known from bones found in middens. Hunting is the most likely cause of extinction.[55]
New Zealand stiff-tailed duck	Oxyura vantetsi	North Island and South Island[29]	Extinct before European contact. Hunting is the most likely cause of extinction, and a bone found in the South Island may have come from a human midden.[56]

South Island adzebill	Aptornis defossor	South Island[29]	Most recent bones were dated to 1234–1445 CE.[51] The presence of adzebill bones in middens indicates that early Polynesian settlers hunted the species, and this is the most likely cause of extinction.[60] Nests could also have been raided by Polynesian rats.[43]
North Island adzebill	Aptornis otidiformis	North Island[29]	Most recently dated to around 1000 CE, but believed to have survived until Polynesian arrival.[43] The presence of adzebill bones in middens indicates that early Polynesian settlers hunted them, and this is the most likely cause of extinction.[61] Nests could also have been raided by Polynesian rats.[43]

Chatham rail	Cabalus modestus	Chatham Islands[29]	Last recorded between 1893 and 1895. Extinct due to habitat destruction, competition with and predation by introduced mammals.[62]
Snipe-rail	Capellirallus karamu	North Island[29]	Excavations at Lake Poukawa, Hawke's Bay show that snipe-rails were once common but drastically reduced in numbers after Māori colonisation and the vegetation changed from podocarp forest to bracken and scrub, likely because of fire. However, the main factor of extinction was probably predation by Polynesian rats.[63]
Hawkins's rail	Diaphorapteryx hawkinsi	Chatham Islands[29][64]	Last recorded in 1895. It was hunted to extinction.[64]
Chatham coot	Fulica chathamensis	Chatham Island[29][65]	Remains dated to 701–119 BCE, but believed to have survived until Polynesian arrival c. 1350 CE.[39] Probably became extinct due to overhunting and predation of eggs and chicks by Polynesian rats. Its bones are common in middens, indicating that it was frequently taken for food.[65]
New Zealand coot	Fulica prisca	North Island and South Island[29]	Extinct due to overhunting by early Māori. Its bones are common in two archaeological middens in coastal Marlborough, where some coot bones were shaped into tools.[66] Nests could also have been raided by introduced predators.[43]
Dieffenbach's rail	Hypotaenidia dieffenbachii	Chatham Islands[29]	Last collected in 1840. It was possibly driven to extinction by introduced predators and habitat loss due to fire.[67]
North Island takahē	Porphyrio mantelli	North Island[29]	Restricted to high altitude grasslands, this species declined with the expansion of forests in the Holocene but survived until hunting by the Maori drove it to extinction. There is a disputed historical observation from 1894.[68]

North Island snipe	Coenocorypha barrierensis	Little Barrier Island,[70] Browns Island (disputed),[70] and North Island[70]	Subfossil remains found across the North Island. A possible live individual was shot on Browns Island in 1820, and another was collected on Little Barrier Island in 1870. It is presumed extinct due to predation by Polynesian rats on the North Island and by feral cats introduced by Europeans on smaller islands.[70]
Forbes's snipe	Coenocorypha chathamica	Chatham Island[71] and Pitt Island[71]	Presumed extirpated by Polynesian rats on Chatham Island between 1500 and 1800 CE, and by feral cats on Pitt Island by the late 19th century.[71]
South Island snipe	Coenocorypha iredalei	South Island, Stewart Island, Jacky Lee Island, Big South Cape Island,[72] and possibly other offshore islands[72]	Extirpated from the larger islands due to predation by Polynesian rats and from the smaller ones by black rats. The last population in Big South Cape Island disappeared in 1964 after a failed relocation attempt.[72]

Chatham penguin	Eudyptes warhami	Chatham Islands,[76] North Island, and South Island[76]	Last dated after the 13th century.[77] It was almost certainly extinct before Europeans arrived in the Chatham Islands;[78] a crested penguin captured alive in 1871 or 1872 was probably a vagrant of another species in the same genus.[79][80]
Richdale's penguin	Megadyptes antipodes richdalei	Chatham Islands[81]	Last dated after the 13th century. It was hunted to extinction.[77]
Waitaha penguin	Megadyptes antipodes waitaha	North Island,[82] South Island,[29][83] Stewart Island,[83] and Codfish Island / Whenua Hou[29]	Last dated to 1347–1529 CE.[82] Archaeological remains indicate that early Polynesian settlers hunted the species and that this, with possible additional predation by Polynesian rats and dogs, was a probable cause of extinction.[83] After its extinction, the subantarctic subspecies of the yellow-eyed penguin, M. a. antipodes, colonised Stewart Island and part of the South Island from the Auckland and Campbell Islands.[82]

New Zealand bittern	Ixobrychus novaezelandiae	South Island,[29][86] North Island[86][29] and Chatham Island[29][87]	Last definite records from the mid-1890s.[87] Scarcity during colonial history may have been due to early spread of brown rats and feral cats throughout New Zealand; a captive bird showed alarm at the presence of a cat. Final extinction coincided with the first expansion of stoats on the West Coast Region, before the wetlands were drained for farming.[87]

Eyles's harrier	Circus teauteensis	North Island and South Island[29]	Last dated to the first millennium CE[51] but believed to have survived until Polynesian arrival c. 1280.[39] There is a dubious observation from the 1870s.[43] It is thought to have become extinct due to a combination of human-induced impacts: its forest and shrubland habitat was burned off and replaced with grassland, predation by introduced Polynesian rats probably caused a decline in its prey species, and hunting by humans is apparent from the presence of harrier bones in middens, and use of its bones to make tools. The Polynesian rat and dog may have also preyed on chicks. Unlike the closely related swamp harrier which colonised New Zealand after its extinction,[88] it was probably too heavy and small-winged to hunt over open grassland areas.[89]
Haast's eagle	Hieraaetus moorei	South Island[29][90] and Stewart Island[90]	Most recent eggshell fragments at Wairau Bar were dated to 1320–1350 CE.[35] It became extinct around the same time as all moa species. Overhunting of its moa prey was probably the main cause of its extinction. Loss of habitat due to the burning of dry mosaic forests and shrublands may also have caused declines in its prey species. Haast's eagle may also have been hunted because its bones, some of which were found in middens after being worked into tools.[90] Nests could also have been raided by feral pigs and rats.[43] Two claimed sightings from the 1800s are unlikely to have been Haast's eagle.[90]

Laughing owl	Ninox albifacies	North Island, South Island, and Stewart Island[29][d]	Though possibly declining in the North Island before major European settlement, it was reportedly common in the Urewera Ranges in pre-European times. Only two specimens were collected from the North Island, now lost. They were common in the South Island in the mid-1800s, but thereafter declined rapidly. The last specimen was collected in 1914, and they were probably extinct by 1940. Polynesian rats formed an important part of the owl's diet and is unlikely to have contributed to its extinction. Instead, the rapid decline of the laughing owl has been attributed to predation and competition by stoats, ferrets, and weasels introduced to control rabbits in the 1880s,[91] as well as feral cats.[92]

Lyall's wren	Traversia lyalli	Stephens Island,[29] North Island, and South Island[29]	Disappeared from the main islands after Maori settlement, likely because of habitat loss and predation by Polynesian rats. It lingered on Stephens Island until 1895, when it was exterminated by domestic cats.[95][96]
Bushwren	Xenicus longipes	North Island, South Island, Stewart Island,[29] Kapiti Island, Big South Cape Island, Solomon Island and Pukeweka offshore Stewart Island[97]	Extinct since 1972 due to predation by feral cats, rats, weasels, and stoats.[43]
North Island stout-legged wren	Xenicus jagmi	North Island[81]	Extinct after Māori settlement but before European contact. Sometimes considered conspecific with X. yaldwyni.[98]
South Island stout-legged wren	Xenicus yaldwyni	South Island[81]	Extinct after Māori settlement but before European contact.[99]
Long-billed wren	Dendroscansor decurvirostris	South Island[29]	Extinct shortly after Māori settlement.[100] Its flightlessness and probable ground-nesting habits would have made it easy prey for Polynesian rats.[100]

North Island piopio	Turnagra tanagra	North Island[29]	Last known individual killed at Ōhura, south Waikato, in 1902. Unconfirmed sightings continued into the 1970s, mainly from forest behind Whanganui, inland Taranaki and Te Urewera. It is likely that predation by introduced black rats was the main cause of extinction, though birds were occasionally eaten by settlers, and their final disappearance coincided with the spread of stoats.[103]
South Island piopio	Turnagra capensis capensis	South Island and some Fiordland islands[29][104]	Declined rapidly following European settlement, especially after 1870. It was extinct on Banks and Otago Peninsulas by the 1880s, and on the West Coast and Fiordland by c. 1895. This coincided with the spread of introduced black rats and later, stoats. Unconfirmed sightings persisted into the 1930s, with the last in west Otago in 1963. Suggestions to transfer South Island piopio to an offshore sanctuary such as Kapiti Island or Little Barrier Island never eventuated, as live capture was very difficult before the invention of modern mist nets.[104]
Stephens Island piopio	Turnagra capensis minor	Stephens Island	Last collected in 1897. Became extinct following clearance of the island's forest and introduction of cats by lighthouse keepers.[104]

Huia	Heteralocha acutirostris	North Island[29]	Last accepted sighting in 1907, but it's likely that a few persisted into the 1920s.[106] Predation by introduced mammals and, to a lesser extent, human hunting, was the likely cause of extinction. Large areas of native forest containing huia were logged or burned in the 1800s to make way for farming, but this would have caused a modest range reduction rather than being a major contributor to extinction. Māori traditionally prized and wore huia tail feathers as a mark of status. Tail feathers became fashionable in Britain after the Duke of York was photographed wearing one during a 1901 visit to New Zealand. Overseas bird collectors and museums bought mounted specimens and tail feathers. Austrian naturalist Andreas Reischek took 212 pairs between 1877 and 1889. Walter Buller recorded that 11 Māori hunters took 646 huia skins from the forest between Manawatū Gorge and Ākitio during one month in 1863. Gilbert Mair recorded eating 'a splendid stew of Huia, Kaka, Pigeons & Bacon' with Buller at a bush camp in Wairarapa, October 1883, after shooting 16 huia and capturing live birds. Thousands of huia were exported overseas. Protection measures enacted in the 1890s were poorly enforced. Two male birds kept at London Zoo in the 1880s died in captivity. Plans to transfer huia to Kapiti and Little Barrier Island reserves never eventuated. A pair captured in 1893 for transfer to Little Barrier was acquired by Buller and apparently sent to Baron Walter Rothschild in England.[106]

South Island kōkako	Callaeas cinereus	South Island[29] Stewart Island,[107] and offshore islands[107]	The main cause of decline was predation by black rats (introduced in the 1860s), cats, stoats, and weasels (1880s in the latter two's case). It was described as rapidly approaching extinction in 1889, when the related North Island kōkako was still relatively common. It has been suggested this difference was due to the tendency of South Island kōkako to spend longer feeding on the forest floor and to nest closer to the ground, making it more vulnerable. Like huia, South Island kōkako were described as ecologically naive. An incubating bird tolerated a close approach without giving an alarm call or defending its young. Māori traditionally hunted them, and large numbers were killed for sale to European collectors and museums. Declared extinct by the Department of Conservation in 2008, the species' conservation status was moved from extinct to data deficient in 2013 following the acceptance of a sighting near Reefton on the West Coast Region of the South Island in 2007.[108] Another unconfirmed sighting took place in the Heaphy Track in Kahurangi National Park in 2018.[109] A 2021 sighting and recording from Heaphy Track is undergoing analysis.[110][111] In 2019, the IUCN Red List estimated the probability of the species being extant as 0.898 based on records and surveys and 0.220 based on threats. Despite this high probability, recent reports are not deemed credible and so the species is considered Possibly Extinct.[107]

Black robin	Petroica traversi	Chatham Islands	Extirpated from the larger islands by the 1870s as a result of forest clearance by European settlers, and predation by introduced cats and rats. The population of Mangere Island followed after cats were introduced in the 1890s. The last seven individuals were captured in Little Mangere Island in 1976 and transferred to a controlled breeding program in Mangere, where cats had died out by then.[113] The species has since been successfully reintroduced to Mangere and Rangatira Island.[114]

New Zealand grayling	Prototroctes oxyrhynchus	North Island and South Island[121]	Abundant at the time of European settlement in the 1860s, population decline was noted by the late 1870s. By the 1920s the species was known to exist only in some streams in the East Cape, Wairarapa, and Otaki districts in the North Island, and on the West Coast of the South Island. Even in these areas, specimens were rarely encountered. In the early 1930s a specimen, possibly the last, was brought to the British Museum, though the origin and date of collection were not noted. The extinction was possibly due to a combination of factors including over-exploitation, deterioration of the freshwater habitat through clearance of forest cover resulting in increased light penetration, raised water temperature, and invasive salmonids.[121]

Adams mistletoe	Trilepidea adamsii	From the Waipoua River to the Waikato and Coromandel Peninsula in the North Island; Great Barrier Island, and Waiheke Island[129]	Last collected in 1954 from Maungakawa in the Pakaroa Range, east of Cambridge. Habitat loss, over-collecting, loss of pollinators and dispersers, and possum browse have all been proposed as contributors to its extinction.[129]
