Two people were killed when a light plane and a helicopter collided in mid-air north of New Zealand's capital Sunday, police said. The two who died were in the helicopter which, crippled by the collision, crashed onto the roof of a hardware store in the coastal settlement of Paraparaumu, said a police spokesman, who was not authorized to speak to media about the crash. Nobody inside the building was hurt. The light plane crashed onto a street, narrowly missing a house. The pilot, the sole occupant, was taken to a hospital in critical condition, emergency services said.
