Multiple flights at Wellington Airport have been delayed "indefinitely" due to low clouds and extreme fog blanketing the capital.
According to the airport's arrivals and departures board, several incoming flights from Melbourne, Christchurch, Queenstown and Brisbane have been diverted.
Departures to Melbourne, Sydney, Nelson and Picton have also been delayed "indefinitely".
According to a Newshub reporter at Wellington Airport, domestic flights to Auckland, Nelson, Blenheim, Hamilton, Tauranga, New Plymouth and Christchurch have recently been cancelled.
MetService says the capital's low cloud has caused limited visibility, resulting in flight delays and diversions. A spokesperson told Newshub that the weather is currently being monitored in Rongotai, where the airport is located.
"The low cloud in Wellington may possibly spread to Hutt Valley this afternoon," the spokesperson said.
Although the "fairly heavy" fog has since lifted in some areas of the capital, there is no definitive answer on when the conditions will clear.
The majority of Sunday evening's departures have been cancelled, although Newshub's reporter says one flight is attempting take-off.
"Low cloud and fog at Wellington Airport is affecting a number of our services into and out of Wellington this afternoon," an Air New Zealand spokesperson told Newshub.
"Customers are asked to keep an eye on the Arrivals and Departures page for the latest information."
A Jetstar spokesperson said that "impacted customers have been given the option to fly on the next available service at no additional cost, or a voucher to the full amount of their booking".
"We appreciate disruptions are frustrating however safety is our top priority."
The spokesperson confirmed that three Jetstar flights between Auckland and Wellington have been cancelled due to the thick fog and "unfavourable weather".
