Moriori karāpuna, or ancestors, were the waina-pono, the original inhabitants or tangata whenua, of Rēkohu, Rangihaute, Hokorereoro—South East Island—and other nearby islands making up the Chathams. Moriori arrived some time between 1000 and 1400 CE, and all Moriori hokopapa are descended from the founding ancestor Rongomaiwhenua. Māori accounts put the number of Moriori killed in 1835-36 at around 300, or about one-sixth of the population. Those Moriori who survived the invasion were enslaved and forced to do manual labour.
