Police have formally identified the mother and son killed in a fiery road crash in Manawatu.
They were 51-year-old Margaret Jane Turnbull and father-of-one Trent Cole Whitburn, 20, of Levin.
The pair died in a three-vehicle crash on State Highway 1, near Sanson on Wednesday..
"The crash investigation is ongoing and there is still a lot of information to be sourced and reviewed before any conclusions can be drawn especially in relation to any potential criminal charges," acting Detective Sergeant Shelly Ross of the Manawatu CIB said.
Central House Movers, the company contracted to transport a catamaran that was travelling in front of Ms Turnbull and Mr Whitburn's Nissan car, was not involved in the crash, she said.
