The temporary freezing of Dunedin's economy in this week's snowfall has cost the city "upwards of $10 million," Otago Chamber of Commerce chief executive John Christie said.
Although it was impossible to know exactly how much productivity was lost, Mr Christie estimated it was close to the value of Dunedin's daily gross domestic product.
"It's certainly in the millions, probably upwards of $10 million. It ground the city to a halt."
He spoke with "very disgruntled" Dunedin employers yesterday about what they claimed were exaggerated traffic restrictions and warnings on Tuesday.
Mr Christie said some Dunedin employers were frustrated about the conflicting and confusing information publicly available in regards to where and when it was safe for people to travel.
