Captain McGearty was a highly experienced pilot for Air New Zealand, holding the top rank as a C7 Boeing 777 captain. Upon turning 65, international aviation rules limited his ability to fly certain routes. Air New Zealand, citing both international standards and its collective agreement with the pilots’ union, placed him on leave without pay and offered him a less senior position on a different aircraft. Captain McGearty declined, arguing this would unfairly reduce his status and earnings.
He brought a personal grievance claim, alleging unjustified disadvantage and unlawful discrimination based on age. The dispute centred on whether Air New Zealand had acted fairly and lawfully, and whether the collective agreement or international rules justified its actions. The pilots’ union intervened, supporting Air New Zealand’s interpretation of the agreement.
