Collisions had almost occurred as a result, he said.
Yesterday, police issued 12 tickets between 7.30am and 8.45am. Mr Hunter said he counted 25 other motorists carrying out the dangerous manoeuvre but they were unable to fine these drivers because they were already dealing with others.
Mr Hunter said most of the drivers police stopped yesterday morning said they knew they were not allowed to use the left lane "but said they did not want to wait in the long queue in the right lane so always did this every morning".
Mr Hunter said police were also aware of many crashes that went unreported. "Someone's going to get injured," he said. "All it needs is for a truck coming out of Matapihi Rd then a car into the side of it and it could be quite different."
At Owens Place, Zone Cafe owner Jenny Fraser said she arrived at work early and did not experience much bother at the roundabout but she knew of many people who did. "A lot of my older customers won't even use it if they don't have to. They're too scared to," she said.
Lighting Plus Mount Maunganui manager Brent Smith uses the roundabout at peak times and said the cars travelled "pretty swiftly".
As a result, other traffic had to be quite quick to avoid collision, he said. "It's not good, especially when it's wet and dark it can be quite tricky. Then you've got overly cautious drivers that just don't go. It's a bit of a nightmare."
Police plan to continue targeting the roundabout until drivers changed their behaviour.
