One bottle store chain reported an 1800 per cent spike sales yesterday, New Zealand Alcohol Beverages Council executive director Bridget MacDonald said.
One outlet also reported a 10-fold increase in trade with spirits under significant demand as they would not be available in supermarkets.
"It is unprecedented," MacDonald said. "It's significantly busier than Christmas.
"We understand that consumers want to ensure they have stocks in hand for the four week isolation period, but a rush on product is not going to help anyone."
