A scene investigation's underway south of Nelson after a milk tanker went off the road this afternoon, killing the driver, after he'd been stung by a bee.
The incident happened just after 2.30pm on the Kohatu-Kawatiri Highway on State Highway 6.
Police earlier told the Herald the driver appeared to have been stung by a bee before crashing off the road.
He died at the scene.
A crane will need to be used to remove the tanker from scrub.
This part of the highway is now closed and a detour will add about 40-minutes to people's journeys.
