A pilot sacked for having sex with a flight attendant and drinking on an overnight stop has won a "relentless" legal battle to save his job.
Regional airline Air Nelson has exhausted its legal avenues after its decision to dismiss the pilot for "serious misconduct" was overruled.
The flight attendant, then 19, said she could not have consented to sex but her complaint to police did not result in a prosecution.
The Employment Relations Authority found the pilot's dismissal was justified. But the Air New Zealand subsidiary was ordered to reinstate him after the Employment Court ruled the airline's investigation into what happened on the overnight stop was "fundamentally flawed".
The airline finally asked the Court of Appeal for the right to challenge the Employment Court decision but has been rejected.
