Thick fog that cancelled and delayed flights in and out of Christchurch this morning has now lifted.
Hundreds of travellers were stuck at Christchurch International Airport after a thick layer of fog grounded planes.
Air New Zealand flights from Wellington, Auckland and Queenstown were cancelled, while JetStar flights from Auckland and Wellington have been delayed.
International flights, however, appear largely unaffected.
An airport spokeswoman said the fog lifted about 10.30am and "things are now back on track".
"The only issue is that until planes actually land here, we don't have aircraft to take people away again," she said.
Passengers are advised to contact their carriers or check the airport's website for updates.
