The Legislative Assembly sits seventeen People's Representatives, elected by the citizens, and nine Nobles' Representatives, elected by the nobility. The Niuas are the smallest of the four constituencies of the nobility, and the only one to elect only one representative. It covers the islands of Niuafoʻou and Niuatoputapu, and thus the lands allocated to three of the Kingdom's thirty-three titles of hereditary nobility. The holders of these three titles constitute the constituency's electorate, and its pool of candidates. Thus, the four nobles in the Niuas (Lord Fusituʻa, Lord Fotofili, Lord Maʻatu and Lord Tangipa) elect their representative among themselves. (In parallel, the Niuas also form a constituency for the people's vote. The Niuas send one noble and one people's representative to Parliament, in separate votes. The May 2014 by-election concerned only the nobility.)
