Ecologically, the Auckland Islands form part of the Antipodes Subantarctic Islands tundra ecoregion. Along with other New Zealand Subantarctic Islands, they were designated a UNESCO World Heritage Site in 1998.[3]
Geography
The Auckland Islands lie 360 km (220 mi) south of Stewart Island, and 465 km (289 mi) from the South Island port of Bluff, between the latitudes 50° 30' and 50° 55' S and longitudes 165° 50' and 166° 20' E.
They include
Auckland Island, the main island, has an approximate land area of 510 km2 (197 sq mi), and a length of 42 km (26 mi). It is notable for its steep cliffs and rugged terrain, which rises to over 600 m (1,969 ft). Prominent peaks include Cavern Peak (659 m or 2,162 ft), Mount Raynal (635 m or 2,083 ft), Mount D'Urville (630 m or 2,067 ft), Mount Easton (610 m or 2,001 ft), and the Tower of Babel (550 m or 1,804 ft). The southern end of the island broadens to a width of 26 km (16 mi).[4]
Here, the narrow channel of Carnley Harbour (the Adams Straits on some maps) separates the main island from the roughly triangular Adams Island (97 km2 (37 sq mi)),[5] which is even more mountainous, reaching a height of 705 m (2,313 ft) at Mount Dick. The channel is the remains of the crater of an extinct volcano, and Adams Island and the southern part of the main island form the crater rim. The main island features many sharply incised inlets, notably Port Ross at the northern end.
The group includes numerous other smaller islands, notably Disappointment Island (northwest of the main island) and Enderby Island (off the northern tip of the main island), altogether covering 12 km2 (4.6 sq mi).[5]
Most of the islands have a volcanic origin, with the archipelago dominated by two 12-million-year-old Miocene shield volcanoes, subsequently eroded and dissected.[6][7] These rest on older volcanic rocks 15–25 million years old with some older granites and fossil-bearing sedimentary rocks from around 100 million years ago.[8]

Climate
Port Ross features a subpolar oceanic climate (Cfc according to the Köppen climate classification system). Like many other Subpolar oceanic climates, Port Ross, along with the Auckland Islands in general, are characterised by the near-constant overcast weather and never being too hot or too cold.
This borders on an extremely mild-wintered, maritime-influenced tundra climate.

Carnley Harbour also features a subpolar oceanic climate (Cfc according to the Köppen climate classification system), though it exaggerates the features shown in Port Ross, as it is much wetter and a lot more affected by ocean-moderation.
The Auckland Islands have a fairly constant cool and wet weather year-round, with neither winter being excessively cold nor summer excessively hot. The climate is most similar to that seen in the Faroe Islands and Aleutian Islands.
History
Discovery and early exploitation
Evidence exists that Polynesian voyagers first discovered the Auckland Islands. Traces of Polynesian settlement, possibly dating to the 13th century, have been found by archaeologists on Enderby Island.[9] This is the most southerly settlement by Polynesians yet known.[10]
The whaler Ocean discovered the islands in 1806, finding them uninhabited.[11] Captain
Whalers and sealers set up temporary bases, the islands becoming one of the principal sealing stations in the Pacific in the years immediately after their discovery.[11] By 1812, so many seals had been killed that the islands lost their commercial importance and sealers redirected their efforts towards Campbell and Macquarie Islands. Visits to the islands declined, although recovering seal populations allowed a modest revival in sealing in the mid-1820s.
The sealing era lasted from 1807 till 1894, during which time 82 vessels are recorded as visiting for sealing purposes. Some 11 of these ships were wrecked off-shore.[12] Relics of the sealing period include inscriptions, the remains of huts, and graves.
Settlement
Now
The Auckland Islands were part of the Colony of New Zealand under the Letters Patent of April 1842, which fixed the southern boundary of New Zealand at 53° south, but they were then excluded by the New Zealand Constitution Act 1846, which defined the southern boundary at 47° 10' south; however, they were again included by the New Zealand Boundaries Act of 1863, an act of the Imperial Parliament at Westminster that extended the boundaries of the colony once more.[14]
Shipwrecks
The Grafton, captained by Thomas Musgrave, was wrecked in Carnley Harbour in 1864. Madelene Ferguson Allen's narrative about her great-grandfather, Robert Holding, and the wreck of the Scottish sailing ship Invercauld, wrecked in the Auckland Islands a few months later in 1864, counterpoints the Grafton story.[15] François Édouard Raynal wrote Wrecked on a Reef.[16]
In 1866, one of New Zealand's most famous shipwrecks, that of the General Grant, occurred on the western coast. Ten survivors waited for rescue on Auckland Island for 18 months. Several attempts have failed to salvage its cargo, allegedly including bullion.[17]
Because of the probability of wrecks around the islands, calls arose for the establishment of emergency depots for castaways in 1868. The New Zealand authorities established and maintained three such depots, at Port Ross, Norman Inlet and Carnley Harbour from 1887. They also cached additional supplies, including boats (to help reach the depots) and 40 finger-posts (which had smaller amounts of supplies), around the islands.[18]
A further maritime tragedy occurred in 1907, with the loss of the Dundonald and 12 of her crew, off Disappointment Island. The 15 survivors lived off the supplies in the Auckland Island depot.[19]
In 2019, a helicopter with three passengers crashed into the ocean near Enderby Island, when they were en route to uplift an ill man on a fishing trawler.[20] The three passengers survived the crash, and were found the next day with only minor injuries.[21] The rescue effort was led by Richard Hayes.[22]
Scientific research and reserve
Three independent scientific expeditions arrived into the Auckland Islands in 1840.
The
From 1941 to 1945, the islands hosted a New Zealand
Currently[update] the islands have no inhabitants, although scientists visit regularly and the authorities allow limited tourism on Enderby Island and Auckland Island.[23]
The marine environment surrounding the archipelago became a marine mammal sanctuary in 1993 and, unusually, also a marine reserve in 2003, measuring 4,980 km2 (1,920 sq mi).[27] The Subantarctic Islands marine reserves around the Auckland, Antipodes, Bounty and Campbell Islands combined form the largest natural sanctuary in New Zealand.[28][29]

By the 21st century the islands had become the primary breeding location of New Zealand sea lions.
Birds
The islands hold important
The whole Auckland Island group has been identified as an Important Bird Area (IBA) by BirdLife International because of its significance as a breeding site for several species of seabirds as well as eight endemic species or subspecies, including Auckland shag, Auckland teal, Auckland rail, Auckland snipe, Gibson's albatross, Auckland Island banded dotterel, Auckland Island tomtit, and the now extinct Auckland Island merganser.[40][39] The seabirds include southern rockhopper and yellow-eyed penguins; Antipodean, southern royal, light-mantled and white-capped albatrosses; and white-chinned petrel.[41][42]

Ecological history
Several
The New Zealand Department of Conservation plans to remove the last remaining introduced mammals from Auckland Island, making the entire island group pest-free, in what would be one of the largest multi-species eradication plans in the world.[47][48] This project started in November 2018, with NZ$2 million of initial scoping work. The total cost for the eradication could stretch to NZ$40–50 million over 10 years.[49]

Legal status
The Auckland Islands – as with all of New Zealand's subantarctic islands – is a National Nature Reserve, afforded the highest possible level of protection under New Zealand law. In addition, a marine reserve encompasses all of the Auckland Islands territorial sea and internal waterways.[2]
All of New Zealand's subantarctic islands are managed by the Southland Conservancy of the Department of Conservation (DOC). Expedition party size, length of stay and landing on the islands are kept to a minimum. Entry is by permit only and applicants must undergo thorough pre-expedition quarantine checks.[2]
