Two people were taken to hospital after a crash on Wednesday morning involving a truck and a van near Te Pohue on State Highway 5 northwest of Napier.
It is believed the van struck the rear of a southbound logging truck-and-trailer, about 4km north of Te Pohue.
The injured men - one aged in his 60s with serious injuries and the other in his 20s with moderate injuries - were taken by St John Ambulance to Hawke's Bay Hospital, more than 60km away in Hastings.
Hawke's Bay DHB staff later said the elder man was being transferred to Wellington Hospital, and the younger man was in a stable condition in a general ward.
Hawke's Bay Rescue Helicopter Service general manager Ian Wilmot said the service was called but after advice from the Hawke's Bay Airport control tower decided low cloud and poor visibility in the crash area meant a flight to the site was not possible.
