A large boulder has smashed into a building in Christchurch after contractors dislodged it from a nearby hill.
The rock took out a fence and left vegetation strewn across a driveway before smashing a large hole into the Avoca Valley Rd garage about 4.45pm yesterday.
"It appears that contractors were up on the hill moving rocks and one has gone across the road and into the garage," police said.
No one was home and no one was injured.
Property owner Kevin Prince was contacted by a neighbour who told him of the damage.
