Fog restrictions lifted at Auckland Airport

Fog restrictions have been lifted at Auckland Airport, after a misty morning in the city.

Twenty one domestic flights out of Auckland were cancelled and approximately 20 delayed after restrictions were put in place at 7:52am. No international flights were affected.

The restrictions were lifted at 10:38.

The Transport Agency also urged drivers to take care, with a blanket of fog covering parts of Auckland.

It said visibility was reduced on some motorways and reminded drivers to increase following distances.

Video posted to Twitter showed cars' lights shrouded by a thick blanket of fog.

Video from NIWA showed the fog rolling in across the city just before 6am, with skyscrapers and buildings disappearing under a thick blanket of cloud.

It's a disappointing start to the school holidays, which are nearly halfway through their first week.

The South Island had a particularly rough start to the break, with Southland lashed by strong cold winds over the weekend.

It didn't get better when the week began with warnings Southland and Otago could be affected by snow flurries, and temperatures dropped a few degrees at the bottom of the North Island on Monday.

Things are expected to settle down towards the end of the week, but weather models are indicating a wet weekend ahead.
