Douglas Myers was born in Auckland in 1938, the son of Kenneth and Margaret Myers. Kenneth's family had lived for generations in the area around Poznan, now in West Poland, but then in Prussia. His great grandfather came to New Zealand in the 1860s by way of the Australian gold-fields and joined a small Jewish community in their new country. Kenneth's grandmother was from the Ehrenfried family, a Jewish family of Hamburg, Germany. By contrast, Margaret Myers (nee Pirie) was born in Canada although she was raised in Costa Rica. Kenneth and Margaret lived in the eastern outer-reaches of Auckland, overlooking the Tamaki estuary.
After schooling at Auckland's King's College, Douglas followed in his father's footsteps and went to Caius College at Cambridge University. He stayed abroad for four years after graduating and was reluctantly drawn home in late 1965 to work with his father in the family hospitality business, Campbell & Ehrenfried.
Following several years of restlessness Douglas Myers developed an ambition to succeed in business not seen in the family since great uncle Louis Ehrenfried's pioneering days. In 1971 he sold most of the company's hotels to New Zealand Breweries, which was more widely known as Lion Breweries, and focused the company's efforts on New Zealand Wines and Spirits, a joint venture between Campbell and Ehrenfield and Lion. In 1972, he took full control of Campbell & Ehrenfried and during the following decade New Zealand Wines and Spirits grew into a major enterprise.
Through a series of clever and courageous manoeuvres in late 1981 and 1982, Myers transformed his half share in New Zealand Wines and Spirits into a controlling stake of Lion Breweries, then one of the nation's ten largest businesses. His first act as Managing Director of Lion was to put the balls back on the lion that had long been the company's symbol.
The restructuring and efficiency drive that Myers led at Lion was required across the entire New Zealand economy. After decades of protectionism prior to 1984, New Zealand businesses had become chronically uncompetitive. Myers devoted much of his time to supporting the reforms begun in 1984 by the Fourth Labour Government. From the mid-1980s, as a foundation member and vice-chairman, and then chairman, of the New Zealand Business Roundtable he used frequent speeches to advocate fearlessly for liberal economic and social policies.
