The son of an elderly Cambridge couple allegedly hit by a truck said he was "very disappointed" at the motorists who passed without stopping to help.

Ron Fey, 70, and his wife, Joyce, 67, were on their daily morning walk on Tuesday when they were hit.

An elderly woman stopped her car in the lane to protect and help the injured couple, but others drove past. The couple's sons, Jonathan and Martin, said they were extremely grateful to the woman and the other people who helped their parents.

"We just want to really warmly thank the people who did stop and assist and got emergency services on the scene," Jonathan said.

"We also want to really thank the police and ambulance and all the hospital staff - they've all been really great."

He said his parents loved to go on morning walks around the lake in Cambridge and normally take a different route home.

"But mum wanted to stop at Countdown on the way home, otherwise they wouldn't have gone that way."

He said he was in a state of shock when a police officer told him his parents had been hit.

Mr Fey was last night in a serious but stable condition in intensive care in Waikato Hospital while his wife was stable and in a ward.

"Mum's up and talking, she's doing really well and she's quite upbeat. But she has got injuries to her right eye and some fractures," said Jonathan.

"Dad's also awake, but his injuries are much more serious. But he's on the road to recovery."

He urged anyone who drove past his parents to contact the police about what they saw.

Sergeant Gordon Grantham, of Hamilton, said police were unsure how the couple were injured but believed they might have stepped into the side of a passing truck. A truck driver who stopped at the scene was interviewed by police.
