Airlines are warning customers of cancellations and delays as adverse weather conditions continue to affect flights around the country.
This morning Air New Zealand recommended customers delay non essential travel or allowed for flexibility as the upper North Island is hammered by a destructive storm, bringing winds gusting up to 140km/h.
"There will unfortunately be significant disruptions across our network today due to the storm and the temporary closure of the Auckland Airport runway which affected many of our flights last night.
"If your need for travel is not immediate or you are only travelling for the day, we recommend deferring your travel," it said.
Due to this advice, the airline is allowing customers to change their ticket to a different flight, in the same class of travel and before April 21, without penalty.
