Wellington Airport is advising passengers to check with their airlines.
Air New Zealand said all domestic flights into Wellington had been held at their point of departure.
"Customers with Wellington flights are strongly recommended to consider deferring non-urgent travel, and those who do need to travel should keep an eye on the airline's Arrivals and Departures page for the latest information," Air New Zealand Senior Manager Customer Care Doug Grant said.
Customers who no longer need to travel automatically have the option to transfer their booking to another date or hold the fare value in credit for up to 12 months toward future travel without the need to advise the airline's contact centre today, he said.
