Another four sets of speed bumps will be installed along Clayton Rd in an effort to slow down drivers on the busy road.
But not everyone is happy, with one road user saying the police could patrol the road more often to deter speeding drivers.
Work on the four new speed bumps, referred to as "traffic calming measures" by Rotorua Lakes Council, is about to start.
The project will cost $27,000, including traffic management, road marking and signs.
Three speed bumps will be placed at the Pukehangi Rd end of Clayton Rd while another will be placed just before the Brookland Rd intersection to slow down traffic around a local school and playcentre.
The council's transport and waste solutions manager Stavros Michael said the average speed along Clayton Rd was 57km/h - 7km/h above the speed limit - and 15 per cent of drivers were going 63km/h or faster.
He said the new speed bumps were being installed for safety, to reduce average speeds and in response to complaints about speeding made by locals.
"All affected residents have been notified," he said.
But Rotorua's Rusty McKnight, who drives along Clayton Rd and back every day, said there were enough speed bumps along the road and questioned the need for more.
"Around 90 per cent of us who drive properly have to drive home over these things every day. Once again the council is wasting money.
"Take them all out, let's drive home on a smooth surface and let the police deal with speeding offenders," Mr McKnight said.
Efforts to speak to local schools and a nearby playcentre were unsuccessful last night.
