Lyons said fog levels were expected to waver before clearing up around 9am, thanks to light westerly winds and cloud.
“It’s extremely unlikely that this would persist for much of the day…But for anyone flying this morning, it could be very inconvenient, particularly for those on the smaller planes,” she said.
“Some of those bigger planes, you’d be shocked what they can land in.”
Visibility at the airport was fluctuating, having been as low as 200m around 6am before improving to 500m.

It’s the second day of disruptions in a row for the airport, with numerous delays and cancellations to domestic regional flights due to fog on Wednesday morning.
Lyons said the current ridge of high pressure was conducive to fog, which was seen across much of the upper North Island this morning, along with low cloud – but that was counteracted by a southwest “cloudy regime” for Auckland.
“It’s not ringing alarm bells that it’s going to be a really foggy week for Auckland…but we keep an eye on that as things get closer to the time.”
