In the period that followed, the Crown's continued acts and omissions eroded what little autonomy Moriori had, causing them to lose their connection to their language and culture and to suffer severe social and economic deprivation. In the late 1860s, the Crown did not consult Moriori karāpuna when promoting the native land laws, nor did it devise a just solution for Moriori regarding land on the Chatham Islands following the Native Land Court's determination of land title in 1870. As a result, Moriori were left virtually landless, their tribal structures were undermined, and Moriori were severed from their land, their wahi t'chap, or wahi tapu, and their responsibilities as guardians and hosts. Over a period of many years, the Crown, through the Colonial Museum, collected, removed, and traded kōimi t'chakat, or Moriori human remains, from Rēkohu. This was but one example of the cultural degradation faced by Moriori.
