The Moriori are the native Polynesian people of the Chatham Islands ("Rēkohu" in Moriori; "" in Māori), New Zealand. Moriori originated from Māori settlers from the New Zealand mainland around AD 1500. 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 (which started as a dialect but gradually became only partially intelligable with Māori), 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.
