French Polynesia's opposition Tahoeraa Huiraatira party has objected to a statement by the centrist Fetia Api party which says the government's majority is being supported by politicians who defect from the Tahoeraa.
The Fetia Api said the ruling coalition wanted to do away with the Tahoeraa system but is now happy to receive Tahoeraa politicians who repent and seek government subsidies.
It went on to say that government behaviour with lavish spending hasn't changed, irrespective of who is in power.
But the Tahoeraa has hit back, saying the current government could only get to power because Fetia Api last year voted for Oscar Temaru's coalition.
In a statement, the Tahoeraa says it will continue its opposition to Mr Temaru's policies which it says will lead the territory to a catastrophe.
The Tahoeraa has lost several members and is now believed to command the support of only 21 members in the 57-strong assembly
