An 8-year-old boy who was the sole survivor from a four-wheel drive involved in a fatal collision with a logging truck and trailer on Tuesday remains in a stable condition at Auckland's Starship Hospital.
Police said the Range Rover carrying five people attempted to make a U-turn from the left-hand side of the road - and into the path of the fully-laden northbound Kenworth truck, north of a turnoff to Uretiti Beach.
Two men and two girls travelling in the car were killed. They were Andy Li, 43, Catherine Li, 10, Xingwu Bian, 47 and Ximeng Bian, 8.
All four were from Auckland.
An 8-year-old boy who had also been in the vehicle was critically injured and was initially taken to Whangarei Hospital and then later airlifted to Starship.
