Ten people have been injured after a van collided with a truck on State Highway 5, near Tarawera, on Monday morning.
Emergency services are responding to the two-vehicle collision on SH5, between Tataraakina Rd and Pohukura Rd, about 9.52am on Monday.
Police said the crash, outside the Tarawera Café, involved a van and a truck.
Initial indications are two people have serious injuries and a further eight have more moderate injuries, a police spokesperson said.
The road is blocked and has been closed from both the Napier and Taupo ends. Police said it would remain closed for some time.
A Tarawera Café spokesman said the crash involved a truck carting wine and a van carrying workers who had just called into the cafe and were pulling back onto the road.
Fluid, thought to be wine, was leaking onto the road after the crash.
A Fire and Emergency New Zealand spokesman said three fire trucks – two from Napier and one from Bay View – are en route to the crash.
"We have also asked for help from Taupo, as it is a collision between a truck and a van," he said.
Hawke's Bay Rescue Helicopter Trust general manager Ian Wilmot said one helicopter is currently on its way to the scene.
A St John Ambulance spokesman said they were notified of the crash at 9.52am and had sent three helicopters, two ambulances and a St John manager in a rapid response vehicle.
Motorists are asked to avoid the area or expect delays.
