Sir Ernest Hyam Davis was a New Zealand businessman, and was Mayor of Auckland City from 1935 to 1941. He was also on other Auckland local bodies and on various philanthropic and sporting organisations. He was Mayor of Newmarket 1909–1910.
Davis was in the brewing industry, first with W Macarthur & Co, later becoming managing director of Hancock & Co. In 1923 New Zealand Breweries was formed. He was a brewery baron for half a century and a master tactician against the Prohibition movement. His brother Eliot Davis was also in the brewing company. During the 1912 Waihi miners' strike the strike leaders were imprisoned, but were released in November for securities of £1600; the bond was later found to have been put up by Davis. He was a major source of funds for the Labour Party for half a century. He was the employer of Michael Joseph Savage for most of the period 1908–1919. He also employed John A. Lee to manage the Palace Hotel in Rotorua from 1929 to 1931 after the latter lost his seat in Parliament.
A millionaire who from 1912 until his death was a very generous financial supporter of the Labour Party... A ruthless businessman, benefactor of worthy causes, and with an eye for the opposite sex.
Davis told Warren Freer, then the Labour candidate for in the 1947 by-election that he was not opposed to state control of liquor outlets, but was opposed to state control of breweries and supported Labour because the Labour Party policy allows a worker to have a few shillings in his pocket and without that he cannot buy my beer. Conservatives tend to look after the more affluent in the country and do not care if the worker has sixpence for a beer or not. Davis was the owner of the Grand Hotel Auckland from 1910 when his parents Moss and Leah Davis retired to London until 1962 when he died himself. He had collected a large amount of Victorian paintings, which hung in the hotel until its closure in 1966 when leased by Hancock & Co. Ltd from the Ara Masonic Lodge. He was also a racehorse owner and yachtsman, and was knighted as a Knight Bachelor in 1937. In 1935 Davis was elected Mayor of Auckland with Citizens' Committee endorsement, narrowly defeating Labour's candidate Joe Sayegh by only 400 votes. He greatly increased his majority when re-elected in 1938. Davis was appointed a Chevalier of the Légion d’honneur by the Republic of France on 2 April 1938 for his services to the French Navy during their visits to Auckland. His award was announced by the French Foreign Minister and recognised the never-failing courtesy and entertainment of French naval crews during visits to Auckland, most notably the cruiser Jeanne d’Arc, which had visited only two months previous. He was a brother of Eliot Davis, MLC.
