Jack Pedley lives on Waterview Crescent and said due to the recent move of the 70km/h speed sign, the intersection has become unsafe for residents and pedestrians.

"We now have to deal with drivers travelling at 70km/h coming towards the intersection, not the 50km/h which we are used to," he said.

The 50-70km/h speed limit transition point recently moved 500 metres to the east, from a location west of Waterview Crescent to a location west of Captain Cook Bicentennial Drive.

A spokesperson from Port Macquarie-Hastings Council said the speed zone change was sparked by a number of community requests.

It resulted in the NSW Roads and Maritime Services (RMS) reviewing the speed limit along Ocean Drive, in the vicinity of Waterview Crescent.

"This review considered a range of factors including the level of roadside development, road alignment and intersection sight distance," the council spokesperson said.

Council installed the required signs in early July to make the speed zone change.

Mr Pedley said he'd like the signs moved back to where they were originally.

He said the speed zone change will make it more unsafe for school children and others, who cross Ocean Drive to use the bus stop opposite Waterview Crescent.

The council spokesperson said the changes have resulted in a more consistent approach to speed zoning on Ocean Drive between Laurieton and Kew.

"A 50 km/h urban residential area speed limit only applies where there are closely spaced driveways," he said.

"The Waterview Crescent intersection, now located in a 70 km/h zone, is treated consistently with other similar intersections on Ocean Drive such as Mission Terrace and Fairwinds Avenue."

Speed limits in NSW are set by the RMS in accordance with the NSW Speed Zoning Guidelines.
