Once it turned green, Stewart and the other pedestrian walked out on to the road. Price failed to see the pair and slammed on his brakes at the last minute but it was too late to avoid hitting Stewart, who was a resident at the adjacent Hilda Ross Retirement Village.
A camera on the dash of Price's truck showed the pedestrian traffic lights turned green nine seconds prior to Stewart, who used a walker, being hit.
When questioned, Price said the last thing he saw was a green light for traffic as he travelled down Ruakura Rd.
Price's lawyer Murray McKechnie said his client did not dispute the facts of the case.
He was also keen to attend a restorative justice conference with the victim's family.
Community Magistrate Stevan Cole convicted Price and remanded him at large until June 25 for sentencing to allow time for him to attend the conference, if the victim's family were willing.
