Air New Zealand is pausing flights in and out of Wellington until 11am due to high winds in the capital.
“High winds in Wellington are currently impacting flight operations in and out of the city. Due to strong gusts, we’ve made the decision to pause services until 11am," Air New Zealand chief operations officer Alex Marren said.
"We’ll continue to monitor conditions closely and reassess throughout the morning. Unfortunately, this will mean delays to services in and out of Wellington today.
"Safety is always our highest priority, and we’ll only restart operations when it is safe to do so."
Customers were advised to keep an eye on the Air NZ app or website for the latest information on their flight.
