Spanish tourists Joan Roma-Serra and Eva Fajula-Rovira didn't stand a chance when a truck jack-knifed and collided with their campervan in Northland in 2009.
Whangarei coroner Brandt Shortland found that driver error was the main cause of the fatal crash on State Highway 1, north of Towai, which occurred as the couple made their way to the Bay of Islands from Auckland.
A 2-1/2-year-old boy was also injured in the accident, and requires ongoing treatment for his injuries.
In his findings, released today, Coroner Shortland said an 84-tonne Mercedes Benz truck and trailer driven by Ioane Etuale lost control as it travelled over a bumpy section of road. It jack-knifed and slid towards the oncoming campervan.
"The left-hand side of the northbound lane was all bank. Therefore the campervan had nowhere else to go. It could not avoid being hit by the truck.''
