2013 Murienua by-election

A by-election was held in the Cook Islands electorate of Murienua on 19 September 2013. The by-election was precipitated by the resignation of sitting MP Tom Marsters following his appointment as Queen's Representative.

Planning for the by-election began immediately following the announcement of Marsters' appointment. Initially the by-election was expected to happen in August, but it was later delayed until September.

The election was contested by two candidates: the Cook Islands Party's Kaota Tuariki and the Democratic Party's James Beer. It was won by Tuariki.
