In February 1941 Newall was appointed
Governor-General of New Zealand, a post he would hold for the remainder of the war. His time there was mostly quiet – described by one biographer as "a nice long rest" Newall and his wife, who also carried out an extensive program of engagements, were broadly popular, but there were occasional tensions; shortly after his arrival, it was widely (but mistakenly) rumoured that he had slighted the "men" of the Army in favour of the "gentlemen" of the RNZAF in a speech. Politically, he had a lukewarm relationship with the Prime Minister,
Peter Fraser – "I can't persuade myself that he is all he quite appears to be", Newall noted in a private report – but the two worked together effectively. Small problems occasionally flared up, such as that in October 1942, when Fraser was reprimanded for not personally informing Newall of the resignation of four ministers. Newall was presented with a government recommendation to
remit four prisoners sentenced to be flogged, but refused to do so. He argued that if the government was opposed to flogging, it should repeal the legislation rather than maintain a policy of always remitting the sentences. This would be constitutionally improper, as it meant that the executive was overriding the legislature, which had provided for the sentence, and the judiciary, which had given it. Fraser, and his deputy
Walter Nash, refused to accept this response, and the impasse stretched out for several days; in the end, a compromise was reached where Newall remitted the sentences but the government undertook to repeal the legislation. The repeal bill was then extended to cover
capital punishment as well; the government had the same policy to always remit, and it was felt that both had to be handled in the same way. A second conflict emerged just before the end of his term, when in 1945, the
Labour government sought to abolish the
country quota, a system that gave additional electoral seats in rural areas. Farming groups – predominantly
National-supporting – strongly opposed the move, and argued that such a major change could only be made after gaining approval in a general election. Newall sympathised, and advised Fraser to wait until after the election, but did not feel it was appropriate to intervene; he assented to the bill. Following his return from New Zealand in 1946, Newall was raised to the peerage as
Baron Newall, of Clifton upon Dunsmoor, in the county of Warwick. He spoke in the
House of Lords rarely, making five speeches between 1946 and 1948 and one in 1959, mostly addressing defence issues. Newall died at his home at Welbeck Street in London on 30 November 1963, at which time his son
Francis inherited his title. ==Arms==
