Police say a man killed when his four-wheel-drive vehicle rolled near Haast early yesterday may have been distracted before the crash.
The vehicle veered off State highway 6, crashed through a fence, rolled and came to rest in a paddock about 6km north of the Haast River bridge.
Craig Bennett, 40, of Australia but formerly of Haast, was thrown from the vehicle and killed.
His 11-year-old son Hunter survived and ran in the dark all the way back to the Haast Junction service station to raise the alarm about 7am.
The boy was still strapped in when the vehicle came to rest, and suffered only a black eye and minor cuts and bruises.
