The remnants of the Kaikoura Ngāi Tahu retreated to the back country, or to the pā along the coast further south. The most important of these places of refuge was the Omihi Pa, north of the Oaro River. In 1829, however, Te Rauparaha returned to the attack. He landed at Kaikoura, but the inhabitants had fled at his approach. He then went further down the coast and attacked and destroyed the pā at Omihi, the reason given for this attack being that the people of Omihi were sheltering the chief Kekerengu, who had taken refuge in the Kaikoura district after being discovered in an affair with one of the wives of Te Rangihaeata, Te Rauparaha's nephew and chief lieutenant. The pā was destroyed and most of its people were killed. Kekerengu escaped.
