He also built there at Heketā the earliest known langi (burial tombs)– Langi Heketā and Langi Moungalafa (where four of his children were buried). But he himself would not arrive in using them. He also made a sporting field to play sikaulutoa (reed throwing stick).
As a prince Tuitātui probably had had a sheltered life, away from others. He did not know that he had an older stepbrother, until the latter stepped forwards one day when the people from the Haangongo tribe came to bring their dues. Fasiapule, as was his name, introduced himself with riddles. The king was impressed and made him a kind of governor.
At one stage Fasiapule needed all his cunning to get rid of two nasty goddesses, named Sisi and Faingaa, who were a white and a black heron. He said he had a surprise for them. If they would sit in coconutleaf baskets and look up at the sky, he would carry them around with a pole on his shoulder. So was done, but when Fasiapule came along a suited tree he hang up the pole with the two baskets over a limb and disappeared. Sisi and Faingaa, still looking at the sky and moving in the wind, thought they were still carried around. Until the baskets had rotten away and they fell through. They started to look all over the country for the evildoer, but he had by then left for Fiji.
This story might be symbolic for the start of a revolt in Samoa by the chiefs Lekapai and Lafaipana, counteracted by Loau Tuputoka and Fasiapule. It would still take a century or so before Sāmoans drove out the last Tongan occupier from their soil.
Nua bore him a son: Uanga. Another son: Afulunga. A daughter: Fatafehi. A last son: Sina. Uanga built the Langi Leka, the first langi in Mua, he also moved the royal court to there after his father's death. But no one knows who were Tui Tonga between Tuitātui and Uanga.
One day the king climbed up on such a raised platform (some say it was on the Haamonga itself) and yelled to his sister, Lātūtama below: "Oh, some big vessels are coming, from Haapai very likely." "Lies!", his sister answered. She was a female Tui Tonga. "Not lies, come up and see it for yourself. It is a large fleet, 1, 2, 5, no 100 boats I think", the king retorted. So the woman went up, and there was of course nothing to be seen. Then the king seized her and had intercourse with her, knowing that no one could see them. Lātūtama's maiden attendants below saw blood trickling down and asked what it was. "Oh, it is from a flying fox", Tuitātui answered. As such the place is still known as Toipeka (blood drip of the peka (flying fox)). But the attendants understood what was going on.
Lātūtama's brothers were enraged on hearing this and swore to kill the king. Tuitātui had to flee to Eua, but even there he did not escape his fate.
Meanwhile Fasiapule had returned from Fiji, and hearing that Tuitātui was in Eua, he, and a Fijian friend, embarked in their canoe to there. They were attracted by a strange light, which on arrival turned out to be the funeral torches of the dead king. Fasiapule killed his Fijian friend, substituted him on the place of Tuitātui and smuggled the body of the latter away from Eua. Approaching Tongatapu, he needed a rest on one of the outer islands, which was named Motutapu (sacred island) from then on, because it had served as a resting place for a Tui Tonga. Then he went on to Malapo. But night came, and the procession had to stop on an island in the lagoon, close to Folaha, and that island is still known as Moungatapu (sacred mountain). Next day Malapo was reached and the body was taken care of by Tuitātui's mother's tribe, the Haangongo.
However, later claims (probably incorrect) are that Tuitātui was not buried in Malapo, but in Mua, or that it even was tried to bring his remains to Sāmoa. But by the time the fleet reached Haapai the corpse started so to stink that the adventure was to abandoned. What happened next is not clear, but people on Uiha claim that in the southeast corner of the island, an ancient grave, which contained the bones of a huge man, is Tuitātui's. But most historians doubt it. It also is claimed that the small islands south of Uiha known as the Otu motu Kinekina, have become a symbol for the Tui Tonga for this reason.
