Pedestrians and drivers may have noticed a traffic island was installed at the intersection of Playfair St and South Rd in Caversham on October 3, only to be ripped up on October 10.
Yesterday, a new traffic island began to take shape in the same spot.
Dunedin City Council group transport manager Richard Saunders said the mistake was because of an error in specifications by the contractor, who was redoing the project at no cost to the council.
Fulton Hogan is the main contractor of the project.
"The size is right, the location is right. It’s just to do with the way it was fixed to the ground."
The council would follow up with contractors on how the error occurred, he said.
"I don’t have the details exactly, but there are things that can go wrong from time to time."
Some disruptions would occur on the road as a new traffic island was installed this week which was "not ideal", he said.
The error was noticed during a routine inspection by council staff.
"It was lucky we found it when we did."
Overall it was "not a huge deal", he said.
