The generic body won the Specialist Importers Trade Tastings award for contribution to the independent trade thanks to its 2006 independents competition, in which Clitheroe-based wine merchant D Byrne's New Zealand wine promotion won partner Tim Byrne a trip to the 2007 Pinot Noir conference.
SITT founder Danny Cameron, of Raymond Reynolds, said: "We should recognise from this year onwards the elements within the trade that contribute to the buoyancy of the independent sector."
New Zealand Winegrowers was one of five finalists for the award and was voted the winner by around 100 interested parties.
"It was a clear winner in terms of votes. What it did for the independent trade by focusing on it and having a very geared campaign, something genuinely targeted towards independents, was something we should recognise on behalf of the independent trade and say well done ," said Cameron.
New Zealand Winegrowers UK director Warren Adamson said: "From our side I think you can only encourage as a generic to work closer with people like SITT. It is a really good concept, a fantastic organisation, and next year we are going to look at how we can work even harder."
The award was presented at the third annual SITT, which drew record numbers of visitors to events in London and Manchester.
