Footage captured by Television New Zealand on Wednesday shows the pilot slowly descending from about 25 feet (8 meters) when the chopper's blades appear to get caught in cables attached to scaffolding. The rear of the helicopter snaps and the pilot is tossed about as the helicopter smashes into the ground.
The television station reports that pilot Greg Gribble, who has 20 years experience, says he's "doing fine" after his ordeal.
