Flights out of Dunedin have been delayed due to poor conditions affecting visibility.
Freezing fog and icy conditions caused low visibility on Friday morning, meaning flights were grounded.
"This morning we are experiencing unusual icy/fog conditions affecting all early morning departures" said Dunedin Airport on Facebook.
So far only one plane has left the airport, after spending two and a half hours on the tarmac.
"It was minus 2 in Dunedin early this morning, and there were reports of freezing fog until about an hour ago," Metservice meteorologist Kyle Lee told Newshub.
"And it's still in the negatives now, so it's pretty cold down there."
Visibility was low due to fog and mist, but Lee says it shouldn't last too much longer.
"It's set to improve over the next hour, so hopefully those delays won't last much longer."
Anyone flying from Dunedin is urged to check with their airlines about delays and cancellations.
