The district chiefs and elected district representatives make up the Rotuma Island Council. The districts are divided into subgroupings of households (hoaga) that function as work groups under the leadership of a subchief (gagaj es hoaga). All district headmen and the majority of hoaga headmen are titled. In addition, some men hold titles without headship (as tög), although they are expected to exercise leadership roles in support of the district headman. Titles, which are held for life, belong to specified house sites (fuạg ri). All the descendants of previous occupants of a fuạg ri have a right to participate in the selection of successors to titles.
