The two members of French Polynesia's anti-independence Fetia Api Party say they will stay away from the assembly session called to debate the no confidence motion against the 15-month old government of Gaston Tong Sang.
The motion was lodged by the pro-independence Union For Democracy last week - two years before the next general election is due.
A Fetia Api statement says again French Polynesia has to put up with weeks of sordid negotiations to get a new majority.
It says the motion has been inevitable because Mr Tong Sang's majority had crumbled to nine members.
It also says the honourable thing would have been for him to resign a long time ago .
