Air travellers face significant delays due to thick fog halting domestic flights at Auckland airport today.
Twenty-two flights were cancelled and 17 delayed.
An airport spokeswoman said there was still thick fog at 11.30am, which was affecting flights to and from provincial towns.
Main flight routes were now operating but there were still delays due to the backlog.
One international flight, a Fiji Airways flight to Suva, was also delayed, by about 3-1/2 hours.
