Air NZ has unveiled a record interim financial result for the first half of the 2014 financial year. The airline says its net profit after tax was $140m - a 40 per cent jump on the same period the year before. Chief executive Christopher Luxon said the hard work of the airline's 11,000 staff had placed the airline in a position where it was able to adapt to a changing economic and competitive environment. A good economic outlook in the airline's 'key revenue markets' was good news, said Luxon, with the airline well placed with new planes arriving soon.
