The notes in the Te Ao Hou article state that this song is reprinted from Rev. Richard Taylor’s Te Ika A Maui. The chant was written by Te Rangitakoru for his new-born daughter and in it he informs her of a story from her ancestry concerning Hau and his wife Wairaka. A point of interest noted by Te Ao Hou is that this song ‘gives the origin of every place-name from Wanganui to Waiararapa.’ S. Percy Smith writes that this ‘song contains a play on the names of the rivers Hau crossed on his journey in search for his daughter’ (135).
