Levin was born in Wellington, New Zealand, the son of English-born parents, Jessie and Nathaniel William Levin, who were both Jewish. From Wellington, he ran the businessW H Levin and Co, a stock and station agency and general mercantile suppliers founded there in 1841 by his father. W H Levin took over the business in 1868 aged only 22 when his father prepared for his own permanent return to London though it was in the event delayed until 1869. His first partners were C J Pharazyn, who withdrew early in 1871, and W W Johnston. After that he conducted the business on his own account as W H Levin until 1889 when he took in Edward Pearce and John Duncan as partners, both had previously managed the business, and it was renamed Levin & Co. His death brought the four-year-old partnership a serious problem. Neither son wanted to go into their father's business. Finally, near three years later, a buyer with the necessary capital was found in Dunedin. In March 1896 Mr Ritchie of the National Mortgage and Agency Company of New Zealand settled current rumours by announcing that his company had taken an interest in a new company, Levin & Co Limited, formed to take over the old established business of Levin & Co. Ritchie advised that the management would remain under the control of the old partners as well as the Levin family.
He represented two Wellington electorates, first the City of Wellington electorate from to 1881, and then the Thorndon electorate from 1881 to 1884, when he resigned due to ill-health. Levin served on the Wellington City Council and the Wellington Harbour Board, and was known for his public benefactions.
Early death
Well-liked and a capable businessman Levin's health had never been strong. He died suddenly at his home in Tinakori Road aged 48 on 15 September 1893 leaving his wife, Amy, daughter of James Edward Fitzgerald and four young children; two sons and two daughters. Learning of his death Parliament closed until the evening session after valedictory speeches. Flags were flown at half-mast by consulates and businesses and a special theatrical performance was indefinitely postponed. He promoted many social and charitable organisations in the Wellington region as well as his business activities.
