Te Rauparaha
In January 1846 fifteen chiefs of the area, including Te Rauparaha, had sent a combined letter to the newly arrived Governor Grey, pledging their loyalty to the British Crown. After intercepting letters from Te Rauparaha, Grey realised he was playing a double game. He was receiving and sending secret instructions to the local Māori who were attacking settlers. In a surprise attack on his pā at Taupo (now named Plimmerton) at dawn on 23 July, Te Rauparaha, who was now quite elderly, was captured and taken prisoner. The justification given for his arrest was weapons supplied to Māori deemed to be in open rebellion against the Crown. However, charges were never laid against Te Rauparaha so his detention was declared unlawful. While Grey’s declaration of Martial law was within his authority, internment without trial would only be lawful if it had been authorised by statute. Te Rauparaha was held prisoner on "HMS Driver", then he was taken to Auckland on HMS "Calliope" where he remained imprisoned until January 1848.
