Air New Zealand customers can automatically transfer bookings to a later flight or hold on to credit for 12 months, the airline says.

A number of customers have been diverted or affected by flight delays today at Queenstown, Invercargill and Dunedin airports.

A large number of flights have been cancelled at Queenstown Airport in particular, where cross-winds continue to affect flight schedules.

A Queenstown Airport spokeswoman was unsure when flights would resume.

Both Jetstar and Air New Zealand flights have been affected, with the Highlanders' scheduled flight from Dunedin to Christchurch at 5.30pm among the weather-related cancellations.

The team is supposed to play against the Crusaders tomorrow night in the Garden City but may be forced to stay in Dunedin until tomorrow morning as an increasing number of flights are cancelled.

Jetstar has cancelled six regional flights today, including one at 4.15pm, and two domestic jet flights have been diverted due to weather - one Auckland to Dunedin and one Auckland to Queenstown.​

Air New Zealand flights between Dunedin and Auckland and Dunedin and Christchurch have also been cancelled.

Air New Zealand is advising customers booked to travel to and from Dunedin to consult the arrivals and departures information on their website here for up to date schedule information.

Customers who no longer require to travel now 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 their contact centre today, an Air New Zealand spokeswoman said.

Air New Zealand would work with customers still requiring travel to arrange re-accommodation on alternative services.
