Rituals, ceremonies, dances and « incantations » were celebrated to « seal deals » with the gods. Whoever broke the law was interfering with sacred circuits and could be sentenced to death. « Uru » (breadfuit), « taro » (yam), « fe’i » (banana plantain) formed the basis of the Polynesians’ diet, out of season of abundance i.e. from April to October, fruits were transformed in paste or fermented and stored in the ground.
This traditional sustainable use plan of ressources disappeared when Polynesian diet was looked down and replaced by imported food from Europe. Only back in 2000, people from Austral islands and Maiao, followed by Teahupoo on the Southwestern coast of Tahiti reinstated the ‘rahui’.
