Wind, rain and fog across New Zealand on Saturday has caused significant disruption to regional turbo-prop services across the Air New Zealand network this school holiday weekend.

Wellington, New Plymouth and Nelson are currently the worst affected ports, while Auckland, Whangarei, Kerikeri, Hamilton, Tauranga, Rotorua, Gisborne and Timaru have also been impacted by Saturday's weather conditions – with flow on impact across the wider domestic network.

Multiple regional turbo-prop services were cancelled or significantly delayed on Saturday and this disruption is likely to impact the schedule into today. Disrupted customers were offered road transportation options where possible yesterday, and the airline is adding additional services to its schedule today to reaccommodate customers.

Jet services operated largely as normal yesterday with some delays into and out of Auckland.

Customers booked to travel domestically were advised to keep an eye on the Air New Zealand arrivals and departures page for up the most up to date flight information.

Customers who no longer needed to travel yesterday automatically had the option to transfer to another flight within 72 hours or hold their fare value in credit for up to 12 months toward future travel. This can be done online through the Air New Zealand self-service booking tool, without the need to call the airline's contact centre.

The contact centre and online customer care teams experienced very high demand yesterday and customers were asked to avoid calling unless absolutely necessary. Travellers already at airports were encouraged to speak to a member of the Air New Zealand team.

The airline is grateful to customers for their patience as it works through these weather challenges.
