Jones had been walking home from a concert in the central city.
Detective Rosanne Rix said the Good Samaritan may have information to help police figure out what happened to Jones.
Rix said the rideshare driver found Jones unconscious but managed to wake him. The rideshare driver offered to call an ambulance, but Jones - unaware of how serious his injuries were - simply asked to be taken home.
Lochie Jones was only 400m from his flat when he was struck, sending him flying through the air and before he fell hard on the gravel and the car kept going.
He suffered a broken sternum, broken vertebrae, cracked and broken teeth, internal bleeding and damage to several organs among other serious injuries.
“It looks like he’s been through some sort of industrial machine, smashing his body around,” Cliff Jones said.
Jones said his son was the “most loveable kid around” and was loved by so many.
He urged the person responsible to surrender themselves to police and pleaded with the public to provide any information they could.
“The sort of person that will leave a boy fighting for his life on the street, lying on a road, you have to question whether they are the sort of people we want on our roads,” Jones said.
“And so to that end, you know, anything the public can do to assist us in finding that person will be greatly appreciated.”
Sergeant Shaun Taiaki, of Wellington road policing, said Lochie was found at the intersection of Kaiwharawhara and Old Porirua Rds between 4.45am and 5.45am.
Jones said with the nature of his son’s injuries, the driver must have known he had hit him and would have damage to their car.
“This did not happen without him knowing,” Jones said.
