French Polynesia's Tahoeraa Huiraatira Party says it has never paid any money to an assembly member, Noa Tetuanui, for him to support its motion of no confidence in 2004 to oust the administration of Oscar Temaru.
The party issued a statement after investigators questioned Mr Tetuanui for more than 24 hours amid suspicion by the public prosecutor that Mr Tetuanui accepted money to defect from Mr Temaru's party.
His switch brought down the government, with Mr Tetuanui accusing Mr Temaru of being incompetent.
The Tahoeraa says Mr Tetuanui stood up for republican values at the time by denouncing the speaker's action to put up a crucifix on the territorial assembly wall.
