Air New Zealand’s head of flight operations Hugh Pearce said the redirection of the flight was due to crosswinds.
“NZ946 from Auckland to Rarotonga was unable to land due to crosswinds at Rarotonga International Airport,” Pearce said.
“The flight will return to Auckland, and consequently, we have unfortunately had to cancel the return service NZ945 from Rarotonga to Auckland.”
Air New Zealand hoped passengers and the aircraft would be able to recommence their journey to Rarotonga as soon as possible.
Pearce said Air New Zealand understood the weather disruption would be “frustrating” but it put the safety of passengers and crew first.
“We appreciate the patience and understanding of our customers while our team works to rebook them onto the next available services,” he said.
Crosswinds can make it difficult for pilots to control the aircraft while guiding it towards the runway for landing, usually causing the aeroplane to drift sideways.
Various factors are considered in deciding whether a flight continues its route, diverts to another airport or returns to its departure airport. When it comes to weather disruptions such as crosswinds, airlines often divert to another airport.
