Vavaʻu is an electoral constituency which sends two representatives to the Legislative Assembly of Tonga.
There are eight titles of nobility attached to Vavaʻu: Fakatulolo, Fulivai, Luani, Tuʻiʻafitu, Tuʻilakepa, Tuita, ʻUlukalala, and Veikune.
As the number of titles of nobility was increased by successive monarchs, a constitutional amendment in 1914 provided that the nobles would henceforth elect seven among them to represent them; the number of peoples' representatives was also decreased to seven.
[5] Lord Luani died in office in May 2010, and it was thus his successor to the title who voted in the November 2010 election.
[6] With the number of voters reduced to eight, the electorate was split evenly between two nobles, who were thus both elected.
