Ra'iātea, is the second largest of the Society Islands, after Tahiti, in French Polynesia. The island is widely regarded as the 'centre' of the eastern islands in ancient Polynesia and it is likely that the organised migrations to Hawai'i, Aotearoa and other parts of East Polynesia started at Ra'iātea. A traditional name for the island is believed to be Havai'i.
