Selected businesses in central Whangārei decided to reopen once the alert level was downgraded and one made hay, selling its stock within 30 minutes.
Cuppacakes Northland on John St usually sells new stock during the course of the day but yesterday, all were gone in half an hour of reopening in the afternoon.
Owner Ashley Telfer said her staff baked about 80 cupcakes, 40 donuts and other things this morning but had to shut shop due to the alert.
They reopened about 2pm and customers flocked in.
"We've had to restock, we already had them made. I knew, based on how the community responded after a change in Covid alert levels, that all I needed to do was to put it out there and people would come in," she said.
