Fog restrictions at Auckland Airport which resulted in the cancellation and delay of a number of regional flights this morning have been lifted.
Auckland Airport spokesman Simon Lambourne said flight restrictions were put in place around 5am but were lifted just before 8am.
The fog caused the cancellation of six regional arrivals and departures. A further 24 regional arrivals and 10 regional departures were delayed.
Main trunk flights and international flights were not affected by the fog, he said.

Passengers were advised to check the airport's website or iPhone App for the latest flight arrival and departure information.
Air New Zealand spokeswoman Brigitte Ransom said the fog caused disruption to the airline's regional Link services.
MetService duty forecaster Liz Walsh said the fog was patchy and was looking like it would remain until around 9am, when southwesterly winds would dissipate the fog.
Fog is also causing problems at Hamilton Airport, grounding flights to both main centres and regional airports.
Three flights from Hamilton to Wellington have been cancelled and a further 12 flights from Hamilton to Auckland, Palmerston North, Christchurch and Wellington Airports have been delayed by more than 45 minutes.
