The driver of a bulldozer jumped for his life yesterday afternoon when it tipped over and rolled down a bank in a forestry block on the Whakarau Road near Te Karaka, inland from Gisborne.
The man, in his 50s, is in hospital in a serious condition with head injuries and a broken arm.
Emergency services were alerted to the accident at about 1pm.
"We sent two ambulances from Gisborne and called in the ECT rescue helicopter to fly the injured driver to Gisborne Hospital," a St John spokesman said.
He was admitted to the hospital's intensive care unit.
"He is in a serious condition," a hospital spokeswoman said this morning.
