Speed bumps installed on Kawaha Point and Ford Rds have failed to meet "exact design height specifications".
Rotorua Lakes Council said in a Facebook post this morning: "Following community concern about the traffic calming measures on Kawaha Point and Ford Rds, the council assessed each of the speed bumps against the required design standard.
"As a result of the assessment we found that some speed bumps failed to meet the exact design height specifications," the post said.
"The contractor is required to correct that mistake and will be carrying out work this week to fix the error. We expect that this work will take about two days to complete and disruption to motorists will be kept to a minimum."
