Te Rauparaha
In 1827-1828 Ngāti Toa under the leadership of Te Rauparaha successfully attacked Kāi Tahu at Kaikoura. Ngāti Toa then visited Kaiapoi, ostensibly to trade. When they attacked their hosts, the well-prepared Kāi Tahu killed all the leading Ngāti Toa chiefs except Te Rauparaha. Te Rauparaha returned to his Kapiti Island stronghold. In November 1830 Te Rauparaha persuaded Captain John Stewart of the brig "Elizabeth" to carry him and his warriors in secret to Akaroa, whereby subterfuge they captured the leading Kāi Tahu chief, Tama-i-hara-nui, and his wife and daughter. After destroying Tama-i-hara-nui's village they took their captives to Kapiti and killed them. John Stewart, though arrested and sent to trial in Sydney as an accomplice to murder, nevertheless escaped conviction.
