Moriori is an extinct Malayo-Polynesian language most closely related to New Zealand Māori. It is the native language of the Moriori, the indigenous people of the Chatham Islands (Rekohu in Moriori), which are east of New Zealand and under its sovereignty.
The invasion from Taranaki had a heavy impact on Moriori population, culture and language, with only 101 Moriori remaining in 1862, and few speaking the language by the 1870s. However, Samuel Deighton, Resident Magistrate on the Chathams from 1873 to 1891, compiled a short vocabulary of Moriori words, with their equivalents in Māori and English. The vocabulary was published as an appendix of Michael King's Moriori: A People Rediscovered.
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.
