The driver of a truck and trailer unit became trapped after rolling their vehicle north of Kaikoura.

A St John spokesman said two ambulances and Nelson rescue helicopter were called to the scene.
The driver was freed and transported via helicopter to Christchurch Hospital's emergency department in a serious condition, he said.
The police spokeswoman later said the track had been transporting "crusher material" from a quarry.
Meanwhile, two people were injured, one seriously, in a crash at the intersection of Cowans and Southbridge-Leeston roads, south of Christchurch about 6.15pm on Tuesday.
