Surrounded by all this Maori opulence, Kiwi grew to manhood. He early developed an arrogant and turbulent disposition. When on a visit to Ngati-Whatua to attend a funeral feast held near Helensville, Kiwi treacherously slew several of the local chiefs and a prominent chieftainess, named Tahataha. Following this up with other murders on his homeward journey, he reached the supposed safety of his tribal domains. The Ngati-Whatua promptly retaliated, and before Kiwi realised their intentions, they arrived in canoes from Pitoitoi (Brigham's Creek, near Riverhead) and successfully attacked the Waitemata foreshore villages. Kiwi then advanced, and met a Kaipara war party coming overland, at Titirangi. After some skirmishing, they defeated Kiwi, who returned to One Tree Hill. The Ngati-Whatua then advanced to the Tamaki Heads, where they captured the Taurere pa, and again returned to Kaipara, losing some of their chiefs in ambush near Remuera. Returning, however, in greater force, one party crossed the Manukau and attacked the Tipitai (Awhitu) and other villages. Kiwi had meanwhile organised his tribesmen, and, reinforced from the southern districts, he advanced against the Kaipara. The forces met again at Titirangi. After much skirmishing, ending in a feigned retreat, the Ngati-Whatua advanced rapidly. The retreat became a "debacle," only ending on the shores of the Manukau, where at Paruroa (Big Muddy Creek) Kiwi fell. All the important Tamaki chieftains fell that day, hence the name of this Maori Bannockburn, "Te Rangi-hinganga-tahi" (The day when all fell together). This battle took place about 1750. Tamaki was now at the mercy of Ngati-Whatua, who advanced, easily disposing of such defenders as remained to dispute their progress. Having depopulated Tamaki, Ngati-Whatua then returned to Kaipara. On their departure, some of the Tamaki refugees again returned to the Waitemata and re-occupied several villages on the harbour side. Ngati-Whatua, hearing of this, sent another expedition, which attacked and finally drove these people away. Tuperiri, the Ngati-Whatua leader, and his tribesmen, then returned to Tamaki and made their home at One Tree Hill and other places. After capturing the last remaining forts at Mangere, they held undisputed sway over this land. Most of the Tamaki people had been slain. Some were enslaved, and a remnant fled into Waikato and Hauraki. Thus ends the story of the ancient tribes of Tamaki. XI _The Ngati-Whatua Era in Tamaki_
