At least two flights have been cancelled as a result of the icy blast down South, while others were delayed this morning due to black ice on the runway in Queenstown.
A spokeswoman for Air New Zealand said weather conditions in Queenstown today had forced the cancellation of one Air New Zealand flight from Christchurch to Queenstown, and as a result the return service going the other way was also cancelled.
"There have also been some delays to flights into and out of both Queenstown and Invercargill today as a result of weather," she said.
Customers were advised to keep an eye on the arrivals and departures page on Air New Zealand's website for the latest flight information.
A spokesman for Jetstar said there were no current delays or issues to its services because of the weather.
