At least 50 people travelling in a LATAM Airlines flight from Sydney to Chile via Auckland have suffered injuries after a “technical problem” caused a “strong movement”, the New Zealand Herald reported, citing the airline.

The flight with 263 passengers and nine cabin crew members landed at Auckland airport as scheduled on Monday afternoon.

The newspaper quoted a passenger who said she experienced a “quick little drop” during the flight.

One person is in a serious condition while the rest had suffered mild-to-moderate injuries, a spokesperson for healthcare services firm Hato Hone St John, which treated roughly 50 people at the airport, said.

The aircraft is an eight-year-old Boeing 787-9 Dreamliner, according to flight tracking website FlightRadar24, and stops in Auckland on its way to Santiago.

Boeing said it was working to gather more information and will provide any support to the airline.

A spokesperson for the South American airline told the Herald there had been a “technical problem” on flight LA800 that affected some crew and passengers.

The airline did not immediately respond to queries from Reuters about the cause and nature of the incident.
