Forty-three years of family winemaking before the first Oyster Bay.

Oyster Bay is younger than the company that owns it. The brand belongs to Delegat Group, an Auckland wine company whose story, as told by New Zealand Winegrowers in a 2022 profile of the family, begins with Nikola Delegat, who emigrated to New Zealand from the former Yugoslavia in 1938, and Vidosava Delegat, who arrived the same year with her parents. The couple married in 1941 and worked on a dairy farm in the Waikato before, in 1947, they planted vines on a four-hectare block in Henderson, West Auckland, and set up a small wine label under the family name.

The next generation took over in 1973. The same profile, written by Sophie Preece and published in August 2022, says that Jim Delegat, then 24, and his sister Rosemari Delegat, then 22, took on the business that year. They planted vineyards in Hawke’s Bay in 1978 and began fermenting Chardonnay in French oak barrels in 1983. The 1980s were hard on New Zealand wine: the profile says an industry oversupply and downturn brought the company close to receivership after it bought its first property on Gimblett Road in 1986, and that the siblings regained the business and returned it to full family ownership in 1989.

The following year they launched a new brand from a different region. New Zealand Winegrowers dates the founding of Oyster Bay to 1990, with its first wine a Marlborough Sauvignon Blanc. That first vintage won a gold medal and the Marquis de Goulaine Trophy for the best Sauvignon Blanc at the International Wine & Spirit Competition in London, according to the profile, and Delegat’s annual reports repeat the claim.

A place name, a single region and a white wine first.

The brand’s identity starts with a regional promise. Delegat describes Oyster Bay as its flagship brand and says its wines come from Marlborough and Hawke’s Bay. The Sauvignon Blanc came first; the range sold today also includes Chardonnay, Pinot Noir, Pinot Grigio and a rosé, and the name sits on still and sparkling wines alike. The trade magazine The Drinks Business reported in 2007 that the company was considering a sparkling wine under the Oyster Bay label, and by 2014 the brand’s American line-up included two sparkling wines, Shanken News Daily reported.

The supply of grapes behind the label has its own corporate history. Oyster Bay Marlborough Vineyards was a separately listed grape grower that supplied the brand. Delegat’s made a partial takeover offer for it in 2005 that, with shares it already held, took its stake to 51.66 per cent, the company announced that August. In 2010 a Delegat’s subsidiary made a full takeover offer for the remaining shares; the Takeovers Panel’s register records that Delegat’s passed 90 per cent in December 2010 and moved to acquire the rest in January 2011, bringing the grower fully into the group.

The brand’s typography has its own short guide on this site: What font does Oyster Bay use? No designer of the original Oyster Bay label is named in published sources, so none is named here.

The family’s place in the industry has been recognised separately from the brand. Jim Delegat won the Ernst & Young Master Entrepreneur of the Year award in 2004, and in 2022, the company’s 75th year, Jim and Rosemari Delegat were both named Fellows of New Zealand Winegrowers, the industry body said.

Design and documentation.

The seven brands in this group are all Australian and New Zealand wine names: Wolf Blass, Lindeman’s, Hardys, Banrock Station, Oyster Bay, Cloudy Bay and Kim Crawford. Wine brands in general sit at many different points in the trade, from family houses that still carry a founder’s name to labels that now belong to much larger drinks groups, and a single brand can be sold everywhere from a corner shop to a restaurant list.

A wine brand’s identity is usually carried less by a single bottle than by a label, a name and the place it promises, because the company behind the name may have changed hands, moved its production or grown far beyond the place where it started. That makes the questions behind each name worth asking plainly: who started it, who owns it now, and where its wine is actually made and bottled.

Each guide separates what independent sources record from what the company says about itself — its founding story, its owners over time, where its wine is made and how its labels have changed — and marks plainly what rests only on the company’s own word.

A listed company that the family still controls.

Delegat’s became a public company while remaining a family one. New Zealand Winegrowers’ profile dates its listing on the New Zealand Stock Exchange to 2006, with Jim and Rosemari Delegat keeping a 66 per cent majority; an August 2005 company release had announced the plan for a share offering led by Westpac. The group crossed the Tasman in 2013, when it bought Barossa Valley Estate in South Australia out of receivership, Decanter reported, describing the deal as Delegat’s first move into Australia.

The brand has been built largely abroad. A 2004 Delegat release said Oyster Bay was then the second-largest super-premium New Zealand wine in Britain, and Shanken News Daily reported in 2014, citing Impact Databank, that Oyster Bay’s sales in the United States rose 21 per cent in 2013 to about 470,000 cases. In its results for the year to June 2025, Delegat Group reported global sales of 3.2 million cases, down 12 per cent, and attributed the fall to American tariffs and distributors reducing their stock. For the year to June 2026, announced on 28 August 2026, the group reported 3.3 million cases, up 4 per cent, along with a non-cash impairment on the assets of Barossa Valley Estate.

The name needs a little care online. Oyster Bay is also a town on Long Island in New York and a bay on the east coast of Tasmania, and neither has any link to the wine.

For a design guide, Oyster Bay shows how a single regional name and a first-vintage trophy can carry a family wine company from a West Auckland vineyard into markets around the world over more than three decades. Compare Cloudy Bay, the Marlborough winery founded five years earlier, and Kim Crawford, another New Zealand Sauvignon Blanc brand. For this guide we use Sounds teal, shell grey and brass with a classic serif, an unofficial interpretation; no product or logo is reproduced.
