On Tuesday, all flights through Wellington Airport were stopped and two international flights were diverted to Christchurch and Auckland after the city was hit by a severe thunderstorm in the afternoon.
Torrents of rain, large hail and surface flooding not only disrupted flights but injured several people and caused widespread damage, cutting power, blocking roads, downing trees and damaging cars, homes and businesses.
Two people needed to be hospitalised and Hutt South MP Chris Bishop said two children were among the injured.
