The French Polynesian Government is calling for France to change its constitution to allow MPs to conduct debates in the Tahitian language.
The bid follows a rejection by the French Government of two proposed laws, after the debate took place in Tahitian, rather than French.
French Polynesia's representative on the French Senate, Richard Tuheiava, says the National Assembly of French Polynesia shouldn't have to ask permission to use its own language.
"The use of the French Polynesian language is something that is inalienable and inherent to the identity of the Maohi people - the native indigenous people of French Polynesia," he said.
"Speaking Tahitian language within the [Assembly] is not something for which we should be asking permission - this is something natural."
French Polynesia is classified as an overseas territory of France, and is made up of a collection of islands whose original inhabitants are the Maohi.
Senator Tuheiava says Polynesian languages, particularly Tahitian are widely spoken across the territory, and Tahitian has been a part of the French Polynesian Assembly since its creation.
"Even though there are five archipelagos, including Marquesas island that has two languages and the Tuamoto islands that has seven languages, the most spoken language throughout French Polynesia is the Tahitian language," he said.
"I would says that 75 per cent of the population here in French Polynesia is Polynesian, and out of this...more than half speak the Tahitian language.
"So it's not really something that's disappearing."
Senator Tuheiava says the French governments annulment of the two local laws does not fit with French Polynesia being re-listed by the United Nations as a non self-governing state.
The United Nations earlier this year has approved an appeal for the territory to be re-listed for decolonisation.
The UN General Assembly will put French Polynesia back on the UN decolonisation list after it was withdrawn in 1947.
