UPDATE 11.30am: Gisborne police have confirmed a man in his 30s is in a stable condition after his car crashed into a pole on Melbourne Road near the Calder Freeway just after 7am this morning.
"He's still stable, he's got some moderate injuries, nothing life threatening," Senior Constable Leonie Earl said.
Senior Constable Earl said police were still investigating the cause of the crash but said it was likely to have been driver fatigue.
She said Powercor were currently at the scene, replacing the whole pole, which broke into "two or three pieces" after the car hit it.
She said the car was travelling at about 100 kilometres per hour upon impact with the pole.
She said there was "significant damage" to the vehicle.
UPDATE 11.10am: Powercor has reported that the pole hit by a car just after 7am was a concrete pole which held up a 66,000 volt line between Sunbury and Gisborne.
A Powercor spokesperson said the pole snapped in half and the line is believed to have come down onto the car.
Crews are on the scene and will likely take most of the day to complete repairs.
Powercor said it was likely there had been a slight variation in power as a result of the accident but because the area was serviced by a number of other lines, there had been no disruption to customer power.
