New Zealand
When the regiment was posted to Sydney, New South Wales, Australia, in 1844, Wynyard was sent on to New Zealand with 200 men to take part in the Flagstaff War against Hōne Heke and Kawiti. Wynyard was present at the siege of Ruapekapeka on 11 January 1846 and in recognition of services Queen Victoria appointed him to be a Companion of the Most Honourable Military Order of the Bath on 2 July 1846.[7] In December 1846 Wynyards returned to New South Wales,[8] then, after an absence of some seven months, returned with the 58th Regiment to Auckland, New Zealand, in July 1847.[9][10] He was promoted to the rank of colonel in 1854.[11] Somewhere along the line he had a sexual relationship with a Maori woman that produced a male child.
When a fire broke out in Auckland, New Zealand, in 1858, eventually destroying an entire city block, Wynyard was personally on the scene directing the men of the 58th Regiment in firefighting efforts.[12]
Superintendent of Auckland Province
Wynyard elected Superintendent of the new Auckland Province on 12 July 1853, beating William Brown. He held the office until he resigned on 5 January 1855. Wynyard's election to the office was controversial, as he was in charge of the colonial armed forces at the time, and effectively deputy to the Governor.[13]: 61 The Colonial Office, on learning that Wynyard had been elected to the office of superintendent, demanded he resign from the role, which he soon did.[14]: 49 He was replaced in the role by his previous electoral opponent William Brown.
Administrator of Government
Wynyard served for two periods (3 January 1854 to 6 September 1855 and 3 October 1861 to December 1861) as Administrator of the Government, in each case between the recall of one Governor and the arrival of the next.
Wynyard opened the 1st New Zealand Parliament on 24 May 1854.[14]: 50 He was quickly confronted by the demands of the new Parliament that responsible government be granted immediately; on 2 June the House of Representatives passed a resolution, sponsored by Edward Gibbon Wakefield, to that effect. Wynyard refused, stating that the Colonial Office made no mention of responsible government in its dispatches. The appointed Executive Council advised Wynyard against implementing responsible government, and in the meantime, he sent a dispatch to London requesting clarification. Wynyard then offered to add some elected members of parliament to the Executive Council, and appointed James FitzGerald, Henry Sewell and Frederick Weld to the council. The compromise worked for a few weeks, but on 1 August Parliament demanded complete power to appoint ministers. Wynyard refused, and all three MPs resigned from the council. In response, Wynyard prorogued Parliament for two weeks. On 31 August he appointed Thomas Forsaith, Jerningham Wakefield and James Macandrew to the Executive Council, but when Parliament met again it moved a motion of no confidence in the members.
Parliament met on 8 August 1855, by which time Wynyard had received instructions from the Colonial Office to introduce responsible government. The new Governor, Sir Thomas Gore Browne, arrived on 6 September 1855 and relieved Wynyard of his duties. He resumed his military career and belonged to the 58th Regiment.[15] On 28 January 1858, Wynyard was appointed to the New Zealand Legislative Council.[16] He resigned on 3 November of that year, as the 58th Regiment was recalled to England.[15][16]
Wynyard's second term as Administrator in 1861 was much less eventful. Filling in between Gore Browne and Sir George Grey, he governed New Zealand for a short period with the advice of responsible Ministers, under Premier William Fox.
