Following Christianization in the 1860s, the offices of sạu and mua were terminated. Colonial administration involved the appointment by the governor of Fiji of a Resident Commissioner (after 1935, a District Officer) to Rotuma. He was advised by a council composed of the district chiefs. In 1940 the council was expanded to include an elected representative from each district and the Assistant Medical Practitioner. Following Fiji's independence in 1970, the council assumed responsibility for the internal governance of Rotuma, with the District Officer assigned to an advisory role. Up until the first coup, Rotuma was represented in the Fiji legislature by a single senator.
