Kaiapoi was now more deeply involved in the feud. A strong war party was sent to join the Taumutu people, and again with reinforcements from Otago, a new attack was launched against Wairewa. Once more Taiaroa sent warning against the defenders, but although many got away from the pā in canoes, they were followed and most of them were killed or drowned. Among those killed were two sisters of Tama-i-hara-nui. This battle ended in a cannibal feast, which was considered particularly atrocious because of the close relationship of the victors and the slain. The war party then went on to attack Purau and Ripapa Island, and although many of the occupants of these villages escaped, some going up the steep hills behind the island and rolling stones down upon their pursuers, very many, including Taununu, were killed.
