AUCKLAND, NEW ZEALANDNew Zealand's civil aviation authority has permitted the Boeing 737 MAX jets to use the country's airspace again

The regulatory body said after a comprehensive safety review the type was granted to resume flights from/to New Zealand. The authority said only Fiji Airways uses the aircraft in New Zealand at this stage.

Permission for the craft to fly here was pulled two years ago.

The authority said aviation regulators around the world put similar conditions in place at the time, which effectively grounded the global fleet.

Since then, Boeing has worked with aviation regulators in the US, Europe, and Canada on system modifications and changes to pilot training procedures.

"We have thoroughly and independently reviewed the work undertaken by Fiji Airways to bring their 737 Max aircraft back into service and are confident these aircraft are safe to return to operation," CAA deputy chief executive David Harrison said.

A date for when the aircraft will resume flying has not been decided.

"Passengers can be assured that no stone has been left unturned to ensure all the necessary safety improvements have been put in place so that when these aircraft return to New Zealand's skies, they do so safely."
