In the decades to come, the Crown's acts and omissions caused Moriori to lose their autonomy and connection with their 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. As a result, Moriori were left virtually landless. The tribal structures were undermined, and Moriori were severed from their land, their wāhi t'chap—or wāhi tapu—and their responsibilities as guardians and hosts.
