"We don't produce $1000 wines, but we also don't produce $5 wines - our market is mainly between the $20 and $50 mark, and we do really well."
Mr Yorke said New Zealand's success on the world wine stage had been gradually building.
Overseas, its wine was renowned for its quality, sustainability and diversity.
"We started winning competitions 25 or 30 years ago with our sauvignon blanc, and we are now getting recognition for our chardonnay, pinot noir and other red wines.
We have always focused on the premium end of the market, and I think that's the key thing here."
At the same time, annual export sales had risen from $300 million eight years ago to around $1.2 billion today, with 53 per cent of sales going to China.
"We see China as a high-end market - it's certainly not a dumping ground - and it's another place for us to establish the New Zealand wine brand as one of the premium brands around the world."
In a blind taste test last year, the Royal Household wine committee chose two New Zealand wines for the Queen's collection.
The committee selected 40 cases of Villa Maria Estate's private bin sauvignon blanc and 30 cases of Palliser Estate Wine's Pencarrow sauvignon blanc 2010 for inclusion in Her Majesty's 5000-bottle wine cellar.
The top five brands in the Drinks International list were Concha y Toro, Torres, Antinori, Penfolds and Jacob's Creek.
