The French Polynesian opposition has lodged a motion of no confidence in the government led by President Gaston Tong Sang.
14 assembly members of the Union For Democracy signed the motion which is scheduled to be put to a vote in two days.
The motion claims that the ruling majority includes opportunists and therefore fails to represent the will of the voters as expressed in the last election.
The Union For Democracy lost power in a no-confidence vote six months ago after the defection of some of its backers to the Tahoeraa.
The opposition's Oscar Temaru has again said that his government's ousting was engineered by the tentacles of France's ruling UMP Party in Tahiti.
The motion comes amid continued rifts within the ruling coalition of so-called pro-autonomy parties.
