Severe gales this week blew a Tranzit bus off State Highway 2, causing the driver to crash through a fence and into a paddock.
The driver, a Featherston man who was the sole occupant of the bus, had just dropped passengers in Masterton and was 3km south of Greytown, on the Tauherenikau Straight, when he was hit by a strong gust of wind just before 7pm on Monday.
Tranzit spokeswoman Jenna Snelgrove said the crash area was "notorious" for wind.
She said another driver had seen the crash unfold.
"He saw a few wobbles at first and then he saw the front of the bus pick up and fire him [driver] off the road."
