Planes can now land or take off from Wellington Airport after a lightning strike disrupted its runway lights, affecting flights in and out of the airport.

A statement from the airport said the issue had affected all aircraft.

At 8.30pm a Wellington Airport spokeswoman said some ground lights on the runway had been restored allowing flights to take off and land following the lightning strike.

"Airways technicians are continuing to work on restoring ground lights to full capacity."

Those booked on flights scheduled to fly in or land at the airport were being told to check the airport's website for up-to-date information.

Several incoming flights were also diverted away from the airport earlier today, and there were delays for those trying to leave.

Air New Zealand had warned customers further disruption is expected today, and travellers should consider delaying any non-urgent travel.

Air New Zealand customers who don't urgently need to fly will have the option to transfer their booking to another date, or hold the fare value in credit for up to 12 months.

The halt on activity at Wellington Airport was the latest in a string of weather-related travel dramas.

Flights were grounded at Auckland Airport yesterday, where winds of 90km/h were recorded and gusts reached up to 120km/h.
