70-570: The Chatham Islands ( / ˈ tʃ æ t ə m / CHAT -əm ) ( Moriori : Rēkohu , lit. 'Misty Sun'; Māori : Wharekauri ) are an archipelago in the Pacific Ocean about 800 km (430 nmi) east of New Zealand's South Island , administered as part of New Zealand , and consisting 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,
140-534: A 'v'. Words in Moriori often have different vowels from their Māori counterparts. The preposition a in Moriori corresponds to e in Māori, the preposition ka to ki , eriki to ariki (lord, chief), reimata to roimata (tear), wihine to wahine (woman), and so forth.</ref> Sometimes a vowel is dropped before a consonant such as na ( ena ), ha ( aha ) and after
210-460: A blessing. By the time the slaves were released in 1863, only 160 remained, hardly 10% of the 1835 population. In early May 1838 (some reports say 1839, but this is contradicted by ship records) the French whaling vessel Jean Bart anchored off Waitangi to trade with the Māori. The number of Māori boarding frightened the French, escalating into a confrontation in which the French crew were killed and
280-486: A brig in late 1842 and sailed to Auckland Island . While Matioro was surveying the island, two of the chiefs who had accompanied him decided the island was too inhospitable for settlement, and set sail before he had returned, stranding him and his followers until Pākehā settlers arrived in 1849. In 1865, the Māori leader Te Kooti was exiled on the Chatham Islands along with a large group of Māori rebels called
350-468: A collection of Moriori texts made by Alexander Shand and published in 1911. The death of the Moriori language went unrecorded, but Johann Friedrich Wilhelm Baucke (1848–1931) was the last man who could speak it. Samuel Deighton's vocabulary of Moriori words was republished as an appendix of Michael King 's Moriori: A People Rediscovered (1989). The language was reconstructed for Barry Barclay 's 2000 film documentary The Feathers of Peace , in

In this regard, it is similar to the Southern dialects of Māori , in which apocope is occasionally found. A vowel is also sometimes dropped after a vowel in the case the preceding vowel is lengthened and sometimes before a vowel, where
490-524: A hundred armed Frenchmen went ashore, burning buildings, destroying waka , and seizing pigs and potatoes. The attacks mostly affected Ngāti Tama, weakening their position relative to Ngāti Mutunga. In 1840, Ngāti Mutunga decided to attack Ngāti Tama at their pā . They built a high staging next to the pā so they could fire down on their former allies. Fighting was still in progress when the New Zealand Company ship Cuba arrived as part of

Chatham and Pitt Islands are inhabited and had a population of 612 in the 2023 New Zealand census , a decrease of 51 people (−7.7%) since the 2018 census , and an increase of 12 people (2.0%) since the 2013 census . There were 390 dwellings. The median age was 44.0 years (compared with 38.1 years nationally). There were 99 people (16.2%) aged under 15 years, 96 (15.7%) aged 15 to 29, 318 (52.0%) aged 30 to 64, and 102 (16.7%) aged 65 or older. Ethnicities were 72.5% European/ Pākehā , 68.6% Māori , 3.9% Pasifika , 2.0% Asian , 1.0% Middle Eastern, Latin American and African New Zealanders, and 1.5% other. People may identify with more than one ethnicity. The Chatham Islands had

Moriori language Moriori , or ta rē Moriori ('the Moriori language'), is a Polynesian language most closely related to New Zealand Māori . It is spoken by the Moriori , the indigenous people of New Zealand 's Chatham Islands ( Rēkohu in Moriori), an archipelago located east of
770-483: A recreation of Moriori contact with Pākehā and Māori. In 2001, as part of a cultural revival movement, Moriori people began attempts to revive the language and compiled a database of Moriori words. There is a POLLEX (Polynesian Lexicon Project Online) database of Moriori words as well. A language app is available for Android devices. The 2006 New Zealand census showed 945 people choosing to include "Moriori" amongst their tribal affiliations, compared to 35 people in

In 1868 Te Kooti and the other prisoners commandeered a schooner and escaped back to the North Island. Almost all the Māori returned to Taranaki in the 1860s, some after a tsunami in 1868 . The economy of the Chatham Islands, then dominated by the export of wool, suffered under the international depression of

In 1841, the New Zealand Company had proposed to establish a German colony on the Chathams. The proposal was discussed by the directors, and the secretary of the company John Ward signed an agreement with Karl Sieveking of Hamburg on 12 September 1841. The price

After generations of warfare, bloodshed was outlawed by the chief Nunuku-whenua and the Moriori society became peaceful. Arguments were resolved by consensus or by duels rather than warfare, and at the first sign of bloodshed, the fight was deemed as over. It has been estimated that
1050-487: A share in ancestral Māori fishing rights. This claim was granted. Now that the primordial population, the Moriori, have been recognised to be former Māori—over the objections of some of the Ngāti Mutunga —they too share in the ancestral Māori fishing rights. Both groups have been granted fishing quotas. Chatham Islands covers 793.88 km (306.52 sq mi) and had an estimated population of 720 as of June 2024, with
1120-506: Is also a potential aquaculture species in Australia. There is already a well established export of wild rock lobster from Australia, especially Southern Australia which currently lands just over 3000 tonnes a year. An aquaculture of this species would serve to bulk up the wild catch and add value with high quality grown lobsters. South Australia currently does have limited aquaculture of Jasus edwardsii , keeping legal sized individuals from
1190-546: Is also commercially cultured in Indonesia and the Philippines. There are three main types of sea cage – floating, wooden fixed, and submerged. The sites for lobster farms should be in shallow water (not exceeding 20 m) and sheltered from currents and swell as well as potential strong winds. Often behind islands and in sheltered bays are the best sites as the sea cages are easily damaged by swell and high winds. Also

The sealing and whaling industries ceased activities about 1861, while fishing remained as a major economic activity. An all-male group of German Moravian missionaries arrived in 1843. When a group of women were sent out to join them three years later, several marriages ensued; a few members of

The National Institute of Water and Atmospheric Research (NIWA) has reared individuals from egg to adult, showing that it is possible to grow this species in captivity, although it takes between 200 and 400 days to reach maturity. This species
1400-467: Is now a technical term referring to those ancestral Māori who settled the Chatham Islands).' The plants cultivated by the Māori arrivals were ill-suited for the colder Chathams, so the Moriori lived as hunter-gatherers and fishermen. While their new environment lacked the resources with which to build ocean-going craft for long voyages, the Moriori invented what was known as the waka kōrari ,

When word of the incident reached the French naval corvette Heroine in the Bay of Islands in September 1838, it set sail for the Chathams, accompanied by the whalers Adele and Rebecca Sims . The French arrived on 13 October and, after unsuccessfully attempting to entice some Ngāti Tama aboard, proceeded to bombard Waitangi. The next morning about

Some ran away from us, these we killed; and others also we killed – but what of that? It was in accordance with our custom. I am not aware of any of our people being killed by them." After the killings, Moriori were forbidden to marry Moriori, or to have children with each other. Māori kept Moriori slaves until 1863, when slavery

Moriori is a Polynesian language that diverged from Māori dialects after centuries of isolation, while still remaining mutually intelligible. The language has a guttural diction and consistent suppression of terminal vowels, meaning that unlike in Māori words may end in consonants. The Chatham Islands' first European contact

They were initially guarded by 26 guards, half of whom were Māori. They lived in whare along with their families. The prisoners helped build
2800-464: The Moriori population, culture, and language was so severe that by 1862, only 101 Moriori remained alive. By the 1870s few spoke the language. The three principal documents on which knowledge of the Moriori language is now based are a manuscript petition written in 1862 by a group of surviving Moriori elders to Governor George Grey ; a vocabulary of Moriori words collected by Samuel Deighton, Resident Magistrate from 1873 to 1891, published in 1887; and
2870-591: The Moriori, enslaving the survivors. Later during the period of European colonisation, the New Zealand Company claimed that the British Crown had never included the Chatham Islands as being under its control, and proposed selling it to the Germans to be a German colony. In 1841, a contract was drawn up for the sale of the islands for £10,000, (equivalent to approximately £860,000 in 2023), but

2940-420: The Moriori. It was formerly believed that the Moriori migrated directly from the more northerly Polynesian islands. However, linguistic research in the early 2000s instead concluded that the ancestral Moriori were Māori wanderers from New Zealand: Scholarship over the past 40 years has radically revised the model offered a century earlier by Smith: the Moriori as a pre-Polynesian people have gone (the term Moriori

This did not stop Ngāti Mutunga from trying to get revenge for the death of one of their chiefs. They were satisfied after they killed the brother of a Ngāti Tama chief. The tribes agreed to an uneasy peace which was finally confirmed in 1842. Reluctant to give up slavery, Matioro and his people chartered

NIWA used primarily brine shrimp to feed the juvenile lobsters, but little is known about a preferred food source. Chopped up mussel flesh has been used previously in Japan. Both these techniques carry some potential disadvantages – brine shrimp can introduce disease, and mussels deteriorate once introduced to

A Moriori survivor recalled: "[The Māori] commenced to kill us like sheep... [We] were terrified, fled to the bush, concealed ourselves in holes underground, and in any place to escape our enemies. It was of no avail; we were discovered and killed – men, women and children – indiscriminately". A Māori chief, Te Rakatau Katihe, said in

Modern descendants of the 1835 Māori conquerors claimed
3850-592: The population numbered about 2,000 prior to European contact. The name "Chatham Islands" comes from the name for the main island, which itself gets its name from John Pitt, 2nd Earl of Chatham , who was the First Lord of the Admiralty in 1791, when HMS Chatham reached the island. The ship, whose captain was William R. Broughton , was part of the Vancouver Expedition . The crew landed on

Maximum total body length is 58 cm (males), and 43 cm (females); maximum carapace lengths 23.5 cm (males), 18 cm (females); minimum legal carapace lengths vary depending on location. In some areas, Jasus edwardsii are frequently harvested weighing over 4.5kg. Jasus edwardsii is prized by consumers in Oceania, China and South-East Asia for its sweet, succulent flesh. Like true lobster, it can be served boiled, steamed, grilled or raw. A$ 250 million worth are harvested every year in Australia alone.

According to Marinov & McHugh (2010), Chatham Island population of Austrolestes colensonis differs genetically from the populations on New Zealand’s main islands, but these differences seem too weak to separate them into two distinct species. Much of the natural forest of these islands has been cleared for farming, but Mangere and Rangatira Islands are now preserved as nature reserves to conserve some of these unique flora and fauna. Another threat to wildlife comes from introduced species which prey on
4550-481: The type of sea cage affects the site, floating and submerged cages can be in deeper water, and wooden fixed cages have to be in water only a few metres deep. Due to the time it takes larva to develop (up to two years) the most cost-effective method of lobster aquaculture is to harvest wild pueruli. This has been done in Vietnam and has been done previously in New Zealand. This would allow a faster grow time to adults as

A study has shown that mussels provide the best food along with a carbohydrate source in the form of agar, allowing faster grow rates in the lobster. The most promising technique for aquaculture in New Zealand is sea cages. These have been successfully used internationally to grow similar species. In Vietnam sea cages are used to grow large amounts of Panulirus ornatus (ornate spiny lobster) in excess of 1,500 t valued at US$ 90 million. This species
