Air New Zealand is to send specialist staff to France this weekend as investigations continue into the crash of an Airbus A320.
The visit is at the invitation of the French investigating body, the BEA.
Personnel from the New Zealand Transport Accident Investigation Commission will also take part.
The A320 crashed into the sea off Perpignan on 27 November, with the loss of seven lives: two German pilots and five New Zealanders.
Air New Zealand chief executive Rob Fyfe says the request from the BEA is no surprise, as it will be seeking expert input into key aspects of the flight.
He says the French agency is indicating it will have a preliminary report available by the end of the month.
