A resident claims ''vicious'' speed bumps on Kawaha Point Rd are still too tall, despite work by a council contractor to shave them down to standard size.
But Rotorua Lakes Council says the speed bumps no longer exceed the standards they once did.
Speed bumps were installed on Kawaha Point and Ford Rds in June, the council said it was at the request of residents and local police.
But shortly after, complaints rolled in were between 10 and 20mm too tall.
Contractors have since returned to the sites and shaved the tops from the speed bumps.
But Rotorua Energy Charitable Trust trustee Jo-Anne La Grouw, who drives on Kawaha Point Rd every day, said in her view the repairs were not enough.
La Grouw commended the council for listening to road users and having some of the tops shaved off the oversized speed bumps but said this had not solved the problem.
"I got [the speed bumps] measured when they were first done and they were almost double the standard height.
"I've remeasured them now with a laser light and they're still over 100mm tall."
La Grouw said cars driving behind buses often need to slow down to 10km/h to tackle the eight speed bumps across 1km.
"That's not traffic calming. I call that traffic frustration.
"I don't have a problem with speed bumps in general but these are overkill. They're vicious."
One Kawaha Point Rd resident, who wished to remain anonymous, called the speed bumps "a pain in the bum".
She said she also drove regularly up and down Ford Rd, where more complaints about speed bump height and location had been voiced by residents and motorists.
"It just seems really odd to me that these two urban roads have ridiculous speed bumps on them.
"I don't remember the council asking the people living here what we thought."
While the recent work had made "some difference", she believed the speed bumps were still too close together.
Rotorua Lakes Council infrastructure and environment deputy chief executive Stavros Michael said letters were delivered to residents before the speed bumps were installed.
"That letter included the number of speed bumps to be built and residents were able to provide feedback at that time. No specific concerns were raised during this time."
Michael said information about the speed bumps had been available on the council's website and in meeting agendas since November.
Regarding the speed bump shortening, Michael said contractors had spent two days on Kawaha Point and Ford Rds correcting the bumps.
"The contractor followed a process of measuring the height difference between the road surface and the apex of the hump," Michael said.
"Where the height of the [speed bump curve] was higher than 100mm a roto-milling machine was used to trim back to the specified height."
Michael said council staff supervised the repair work and a physical template was used to ensure the speed bumps did not exceed 100mm.
A Waka Kotahi NZ Transport Agency spokesperson said while there was no New Zealand national standard for height of speed humps road controlling authorities refer to the Australian Standard.
The Australian Standard Manual of Uniform Traffic Control Devices sets the maximum height of a speed bump at 100mm.
The manual notes speed bumps "that differ from the above may not be effective in controlling vehicle speeds".
The contractor which did the work did not wish to comment.
