French Polynesia's A Tia Porinetia Party has attracted about 3,000 people to its inaugural congress in Papeete.
The gathering was held outside the territorial assembly, a week out from the first round of the election to choose a new 57-member assembly.
The party's leader, Teva Rohfritsch, has been campaigning for a renewal to deal with the economic decline of recent years.
Meanwhile, another pro-autonomy party, Porinetia Ora, has also held a campaign rally in Papeete, attracting an estimated 3,000 people.
Its leader, Teiva Manutahi, was joined for the rally by a French parliamentarian and former presidential candidate, Nicolas Dupont-Aignan, who is the leader of the Arise the Republic Party.
The first round of voting will be on April the 21st, with a run-off round two weeks later for those lists securing at least 12.5 percent of the vote.
