Pickens said the annual vintage was regions one chance to make wine, which occurs from February until April. With wine making supplying a fifth of the local economy and the majority of New Zealand's grapes, it was decided to put a stopper in the wine festival.
Wine Marlborough which hosts the event, represents 700 grape growers and winemakers in the region.
" We know people will have their weekends planned or travel booked," said Pickens, who said it was a disappointment.
"They're still welcome to come and enjoy the region, but a major event of close to six thousand, we just feel is not safe to go ahead with."
Cellar doors will still be accepting visitors under the Covid framework and a raft of independent events will still be taking place as planned.
Tickers will be 100 per cent refunded, and will be processed in the next 15 days.
