 After many days and nights at sea, Ruatapu arrived at Tongatapu where the first person he met was Tapotuki Tonga, who informed him that the island's ariki was Chief Kaukura.Ruatapu stayed with Tapotuki Tonga, growing fond of her, and ended up having another son with her named Moenau.While the child was still young, Ruatapu decided to leave again, but first instructing Tapotuki Tonga's father Rangiura to take Moenau back to Rarotonga to be with Uanukukaiatia and Tamaiva, to share chiefly authority.
