The French Polynesian Government led by Gaston Flosse says the major by-election, in Tahiti and Moorea, will be held in February and it is confident of its prospects despite the political crisis.
Plans for a by-election for 37 of the assembly's 57 MPs are now proceeding following the failure of talks in Paris aimed at paving the way for fresh territory-wide elections.
A government spokesman, Jean Christophe Bouissou, says the by-election must be held before February the fifteenth, but the exact date may not be known for another two weeks.
Mr Bouissou says he believes people will weigh law-breaking activities of the supporters of ousted president Oscar Temaru against his side's respect of law and push for development.
"We can win this election because people, starting today, should be starting to feel really bad about all this blocking and all these kind of actions in breaking the law, made by Mr Oscar Temaru."
