Whatever the case, Tahupōtiki was born in Whāngārā (a place associated with Paikea), around 1450CE. He was given command of the (canoe), and took it down to the South Island where he landed at the Arahura River on the West Coast – or at the Waiau River near Manapōuri. He stayed there for a time before travelling back to Whāngārā in a new canoe upon learning of the death of his brother. As according to ancient protocol, he took Porourangi's grieving wife Hamo-te-rangi as his own, by whom he had at least four sons: Ira-a-Tahu, Ira-(apa)-roa, Tahumuri-hape, and Karimoe. Some say his other sons were Ira-manawa-piko, Rakaroa, Rakahurumanu, Tūroto, Tahutīoro, and Ruanuku.
