French Polynesia's small anti-independence Rautahi Party has been disbanded and its members are being urged to join the ruling Tahoeraa Huiraatira of Gaston Flosse.
Rautahi politicians have already been associated with the Tahoeraa, which has nominated an assembly member elected on the Tahoeraa list, Maina Sage, to be the party's candidate for the by-election to fill a seat in the French National Assembly.
The Rautahi leader, Jean-Christophe Bouissou, says the dissolution comes as the differences seen after the 2004 elections no longer exist.
He split from the Tahoeraa in 2005 after Gaston Flosse refused to act on his by-election promise to resign, should his party lose.
Despite a defeat, the veteran politician insisted on staying on but was immediately removed in a no-confidence vote.
Mr Bouissou says he is open to stand for one of the territory's two French Senate seats which will be decided in September.
Gaston Flosse says he won't seek re-election.
