Since they had killed nobody at Waikakahi, the Kaiapoi warriors feared ridicule. They happened across the nephew of Chief Taununu, of Rīpapa Island, and killed him. In retaliation Taununu overran the Whakaepa , near Coalgate, killing the inhabitants. The Otago attacked Waikakahi again, and although Taiaroa had again warned them, they were pursued and killed. Two of Tamaiharanui's close kin, his sisters, were slaughtered. The Otago and Taumutu parties destroyed the Rīpapa before returning to Otago. Many settlements and communities along Banks Peninsula were abandoned in the series of retaliatory attacks.
