Owen was desperate to get home to see his wife Megan and kids - six-year-old Sarah and three-year-old Eric - but he also wanted to help out.
So as he passed tired, scared people trekking on foot up the Bridle Path, he stopped time and time again to pick them up. He would drop some off at the top - then go back for more.
Eventually, he parked the Land Rover at the top, where the road was blocked, and set out on foot himself, down the Major Hornbrook Track towards his Lyttelton home.
He sent his wife of 17 years another text: "Home in 10."
That was his last contact.
As he walked down the path, almost within sight of home, another aftershock hit. The keen outdoors-man was crushed by boulders.
"He gave a number of people rides up the Bridle Path because they were walking home to Lyttelton from Heathcote.
"We understand that was his last act of kindness," said Owen's brother Anthony.
