The Queenstown Times spoke to seven traders who had experienced footpath, drainage, road surfacing and telecommunications work outside their doors.
While everyone said they thought the street would be improved once finished, they asked why the upgrade had taken so long to complete.
The majority said their business had been impacted as foot traffic was either diverted or bypassed altogether from their premises.
Betty's Liquor Store manager Christine Gilbert said she and staff were dusting the shop everyday and putting up with machinery noise and a service shed parked directly outside.
"Look at what they've plopped in front of my business - a big ugly shed. It's been there since Monday morning, bright and early."
Shoppers "can go to the cash machine but the service shed is blocking my entrance. Right now, no-one's working.
I know people have to have lunch but why don't they take lunch breaks in shifts so work doesn't completely stop?"
Miss Gilbert said she had no idea when contractors would be finished or when the shed would move.
Southern Lakes Info Centre manager Andrew Bisset said there was a "bit of noise" when workmen were outside the door but the final product was looking "really good".
"We haven't found an impact in terms of people getting through the door. It's a small inconvenience that's worth it."
Queenstown Health and Sport Nutrition manager Pip McIlwrick said a service shed had been outside her business for two or three months.
Contractors had apologised for the disruption and explained what they were doing and how long it would take, she said.
"It's starting to look good but it has stopped a lot of customers. Everyone on Camp St has felt it with traffic flow.
"I understand [the council] had to do it and I'm looking forward to when it's all done.
Just the timing of the road works and pavement was not good."
Peter Alexander manager Emma Cameron also said noise and dust affected trade.
Staff had gone to assist an elderly lady who had fallen over while walking on the upturned pavement.
"There were days it was like an obstacle course trying to get in.
Hopefully, it will be worth it and people will come down here and start spending.
"There's no communication from council and we've been kept in the dark over it, really."
Just Jeans manager Robyn Thomas said while the pavement was looking tidier, she and staff were having to dust everyday while contractors were outside for two weeks.
Goldfields owner Trond Johansson said the upgrade was "a joke" that involved the replacement of "perfectly fine grey pavers with grey pavers from China at great expense and time."
He said the timing of the road sealing and street upgrade had "done wonders" for his turnover and he was unconvinced by the end result.
Contractors started repaving the Camp St entrance to O'Connells Shopping Centre last week.
