Both sons accompanied their father when he captained the Arawa canoe on its journey to New Zealand and settled with him at Maketu in the Bay of Plenty.
[5] After this journey, Kahumatamomoe settled down with Tuhoromatakakā near Maketu in a house called Whitingakongako in the pā (fortified village) of Te Koari.
Kahumatamomoe threatened to kill his brother and Tuhoromatakakā attacked him again, ripping a pounamu earring called Kaukaumatua out of his ear.
When he heard of this, Kahumatamomoe came storming in, intending to kill the invader for the insult, but he recognised Īhenga as his nephew, welcomed him, and cleansed him of the tapu.
Then he carried out the pure ritual, cutting off Īhenga's hair and tying it to a stone which was deposited in a sacred place.
Passing the hot springs, Te Pera-o-tangaroa, and Waiohiro stream, they arrived at Ngongotahā (called Parawai by Kahumatamomoe).
[12] Two years later, Kahumatamomoe decided to make a trip to visit his nephew Taramainuku, Īhenga's older brother, who now lived at Kaipara in Northland.
At one point on the journey, they rested under a rātā tree and Kahumatamomoe named the place Te Whakamarumaru o Kahu ("The sun-shade of Kahu"); Īhenga responded by naming the place Te Ure o Tūhoro ("The penis of Tūhoro") after his own father, because he saw a mataī tree with a penis-like growth on its trunk.
After crossing the Waikato River, the younger men became very slow, so Kahumatamomoe named the spot Māngere ("lazy").
They crossed the Waipa River, passed Mount Pirongia and Waingaroa and came to Port Waikato, where they met Ohomairangi, an uncle of Kahumatamomoe, who had come to New Zealand on the Tainui.
To the north, Kahumatamomoe set up a mānuka post as a rahui (sacred marker) and named the place Manuka (which might be Manukau).
[12] At Kaipara, the travellers met with Taramainuku and he gave them his daughter Hinetu-te-rauniao, to be married to Kahumatamomoe's grandson Uenuku-mai-rarotonga.
[13] After this, Kahumatamomoe began his journey home, travelling to Waitematā Harbour, where he placed a mauri stone on Boat Rock.
[14][15] He boarded a canoe at Takapuna, passed Motuihe and Paritu on Waiheke Island, and came to Moehau, where his father and brother had been buried.
