Vainui started dancing at 3 years old.
Trained for fifteen years by the Hula Vahine school, on the island of Raiatea where she was born, her love for this art only grew and asserted itself. At eleven she became the best dancer in the children's category; she participates six times in the Heiva i Raiatea with her group and wins it four times; she dances professionally in hotels and tourist boats on her island.
At the same time, she continues to perfect herself with the greatest: internship at the Tahiti Conservatory, with Teruria Taimana (gold medalist at the conservatory), Moena Maiotui or Lorenzo Schmidt (founder of the Grands Ballets de Tahiti) and Tiare Trompette (Hei Tahiti).
In France she continues to dance and transmit her passion and is currently a teacher, choreographer and dancer on behalf of Mahaora in Haute-Savoie and Geneva.
