The 183 prisoners were taken by boat to the
Great South Road, then marched to
Auckland. They were initially held on the
Marion, an old coal hulk in
Waitematā Harbour before being moved to the disused
copper mine smelter on
Kawau Island, north of Auckland. The prisoners were allowed the use of fishing boats to supplement their diet. Premier
Frederick Whitaker and Colonial Secretary
William Fox, meanwhile, debated bringing charges of
high treason against all or some of them but disagreed on whether they should be tried by the Supreme Court or by
court martial under the Suppression of Rebellion Act, a piece of legislation passed in late 1863 that authorised the Governor to arrest and detain indefinitely anyone suspected of complicity in the "rebellion". The Act provided for punishment by death, imprisonment or corporal punishment such as whipping. Dr Arini Loader, a lecturer at Victoria University of Wellington, has stated that there was a rumour at the time the ship was going to be towed out to the ocean and sunk. "They didn’t know if they were going to be lined up and shot. Neither Grey nor his ministers knew what to do with them," she said. The prisoners were never charged nor tried by any tribunal. On the night of 11 September 1864 the 200 prisoners on Kawau seized all boats on the island and paddled to the mainland using spades, shovels and pieces of board they had fashioned into paddles. The group landed at Waikauri Bay and set up camp on a ridge overlooking
Ōmaha and
Matakana. They refused pleas by the prison keeper to return to Kawau and were eventually permitted by the government to make their way back to the Waikato. Two Victoria Crosses were awarded after the battle: one to Assistant Surgeon
William Temple for disregarding his own welfare in attending to the wounded during the assaults at the end of the day and another to Lieutenant
Arthur Pickard for showing courage in running through enemy fire to reach Cameron and seek help. Cameron attracted both praise for his "skilful measures" in the capture of Rangiriri and severe criticism over the high number of British losses. Yet the battle had highlighted the rapidly growing disparity between British and Māori forces and the inability of Waikato Māori to maintain their manpower continuously because of the need to sustain their tribal economy and attend to domestic needs. Tamehana sent his own
mere to Cameron soon after the battle, and this was interpreted as a token of submission. Several Waikato chiefs including Te Wharepu expressed a willingness to negotiate and on 8 December the Kingite capital at
Ngāruawāhia was abandoned and then taken by Cameron's troops. But Māori were still opposed to the British demands of submitting to the Queen and surrendering all arms and lands and began building further defences south of Ngāruawāhia.
Wiremu Te Wheoro, a chief of Ngāti Naho who was loyal to the government, was installed in a wooden redoubt constructed on a high point east of the main earth redoubt at Rangigiri. Te Wheoro, who served as a magistrate in the Native Land Court—and about 30 of his men manned the wooden redoubt until 1868 to prevent any disruption by Kingites to the British supply line. Te Wheoro later resigned in disgust at corruption within the court and in 1879 entered Parliament as the Member for
Western Maori. == The site today ==
