This affair resulted from some tribal differences in the Waitakerei-Kaipara borderland, about 1680. Kawharu (who was a chief connected with the Northern Ngati-Whatua) attacked the tribes in those districts, driving all before him. He assaulted also many of the Tamaki villages, continuing his campaign until he reached as far as the Paparoa headland, east of Howick. Capturing and destroying the pa there, he returned to Kaipara.

Also descended from the Patu-paiarehe, they had gradually incorporated their pedigrees with those of the Tainui, Arawa and other people. The earliest warfare on record of Tamaki with these people originated (so says the legend) when the Tamaki tribes slew the pet seal belonging to the Hauraki people. Strange to say, this animal (named "Ureia") was on a visit to Manukau Harbour, at the invitation of the Tamaki people, and there it met its untimely end. Surely the most unusual of Maori _casus belli_. Maru-tuahu, as the tribes of the Hauraki district were called, then invaded Tamaki. They attacked among other places the Maunga-whau (Mount Eden) pa. After various other successes they returned homewards. THE MURDER OF KAHURAUTAO Subsequent to this affair was the warfare resulting from the murder of Kahurautao, his son Kiwi, and other Maru-tuahu chiefs. These people were returning from Waikato by canoe _via_ Manukau and Tamaki. They had visited the Tamaki chiefs at Mount Eden and other places, and on their return to their canoes at the Tamaki River they were waylaid and murdered near where St. John's College now stands, hence the name of that place, "Paru-tahi"--killed together. The Maru-tuahu tribes, under Kahu's son Rau-tao, thereupon invaded Tamaki. They attacked with success the riverside pas at Tamaki, also those at Mount Eden, One Tree Hill and Orakei. Crossing to Takapuna, they scoured along the coast as far as Mahurangi. Apparently all those people, being Ngai-Tai, were of one tribal identity. This was not the last time these coastal tribes suffered in this way. KAPETAWA'S INVASION
