Ngati-Whatua were now installed in possession of Tamaki. They soon found that might was the only right to their new territory. To the south were the powerful Waikato and Marutuahu tribes, who by sea and land were a continual anxiety to the new lords of Tamaki. They were closely related to the late victims of Ngati-Whatua. Many of the refugees, indeed, had gone to those districts to live, and no doubt instigated many a surprise attack. Ngati-Paoa appear to have always maintained several fortified villages on the Tamaki River unmolested by Ngati-Whatua down to European times. Quarrels arose with Ngati-Paoa at last as the result of a marriage of a Waikato chieftainess to Te Putu, a Ngati-Paoa chief. Land on the Tamaki River had been given to cement a tribal peace and in honour of the union. Shortly thereafter, at a fishing expedition off Mahurangi, Ngati-Paoa and Ngati-Whatua quarrelled. The former attacked the latter and killed Tara-hawaiki, son of Tuperiri. Ngati-Paoa followed this up by invading Tamaki, having in alliance with them the other Hauraki tribes. The invaders were defeated by Ngati-Whatua at Pu-ponga on the Manukau Harbour and again at Rangi-mata-rau (Point Chevalier Beach). On a later occasion a party of Ngati-Paoa were surprised whilst shark-fishing at Kauri Point,[2] the survivors being left on the pinnacle rock (Niho-Kiore) off there to drown. Thereafter Ngati-Whatua, now in alliance with Waikato and Manukau tribes, attacked Ngati-Paoa at Putiki (Waiheke). In a final battle at Tamaki West Heads, Ngati-Paoa were defeated, and thus was ended that warfare. This event is placed about 1793, and permanently established Ngati-Whatua's prestige and their possession of Tamaki. At this time, Tamaki had become a rather unsafe place of residence, and does not appear to have been extensively occupied. In fact, Mount Eden and many of the large hill forts had long been abandoned, and their elaborate defences were already in ruin and overgrown with scrub and fern. About this period, also, came a great epidemic remembered as the "Rewharewha." It was probably an influenza outbreak, and swept throughout the land. No doubt this visitation further reduced the Tamaki population, and therein lies the reason why many of the old-time villages were abandoned and passed out of history. The remnants of the people, though still numerous, were unable to hold the large hill fortresses against an enemy. Smaller and easier defended positions only were maintained.
