In Hawaiian mythology, according to the Kumulipo he is known as Kaha'inuiahema and according to Tregear, the legends about Kaha’i are 'extremely fragmentary and vague',[1] but they indicate that Hema traveled to 'Kahiki' (perhaps Tahiti, but more probably to kahiki 'the distance', as kahiki can be understood to include all of the islands in the Pacific Ocean) to receive a tribute called palala for the birth of his son Kaha’i.
A rainbow was the path over which he and his brother ‘Alihi ascended into the skies, where they asked Kane and Kanaloa where Hema's remains were to be found.
He then proceeds to Hiva-nui, the land of the goblins, with a strong net called Tukutuhuraho-nui (great spider).
Later, the nude Tahaki and his cousin Karihi go down to the underworld, where his grandmother returns each piece of skin to its rightful place.
In the Samoan version of the legend, Tafa'i, his brother 'Alise, and his sister Ifiifi are the children of Pua and Sigano.
He convinces the goddess Sina-tae-o-i-lagi, daughter of Tagaloa-lagi, to give an audience to the Tafa'i and his brother, who disguise themselves as ugly old men in order to reach her court safely.
Her family convince her to return to earth and marry Tafa'i, to whom she bears La, the sun, who goes to live with her mother in the sky.
