The Porinetia Ora is the latest French Polynesian party to hold a march as part of the campaign for next month's first round of the territorial election.
An estimated 1,000 people gathered at the territorial assembly to hear the pro-autonomy party's leader, Teiva Manutahi, speak.
He plans to walk around the entire island of Tahiti as part of his campaign.
Voters will go to the polls on April the 21st and for a second round on May 5th to elect a 57-member assembly for a five-year term.
There have been no opinion polls but the key contenders are expected to be the pro-autonomy Tahoeraa Huiraatira and the A Tia Porinetia group, which has absorbed the To Tatou Aia as well as a raft of small parties.
There has been one major televised debate but the ruling Union For Democracy stayed away, saying it is still to finalise its list of candidates.
