French Polynesia's public broadcaster says the Tahoeraa Huiraatira Party has approached the National Front of France as the country is heading for presidential and then parliamentary elections.
The report said there had been no official confirmation but it said the Paris office of the National Front had not denied reports it has been in touch with the Tahoeraa, adding it is aware of what is going on.
The Tahoeraa, which is led by Gaston Flosse, backed the Republicans' Nicolas Sarkozy during the primaries but he failed to make the run-off.
In the run-off, the Tahoeraa switched support to Francois Fillon who won the nomination.
However, French Polynesia's president Edouard Fritch and his party this month became Mr Fillon's election partner in Tahiti.
Mr Fritch said he expects Flosse to seek a deal with the National Front as it may be the only group prepared to accept co-operation with his party.
