Rolling fog disrupted a string of flights through Hawke's Bay Airport this morning.
"When it comes down to delays through the weather people are pretty understanding though," an Air New Zealand spokesperson said.
The fog began rolling across Napier and the airport zone just before 7am with the service to Christchurch able to get away just in time.
However, as it thickened two further flights were boarded but passengers spent about an hour in their seats before there was a break in the fog allowing them to depart.
An in-bound flight from Auckland though had to be sent back after circling for nearly 40 minutes waiting for a break which did not arrive.
