Yep, Air NZ is 53% owned by the NZ Government, now as it was sold down by the National government along with numerous power companies.
How much more money did the NZ Government put into Air NZ since that bailout? About $0.
Stands on its own two feet, gets no special benefits from the government here, has to pay full taxes in NZ and even pay the government dividends just like any other shareholder. There is no government debt assurances, discounts on fuel, landing fees, airways charges or CAA charges. They are the same charges as any other airline in NZ get charged, except for Jetstar. They don't pay NZCAA charges, security charges.
The main difference is post bailout, they have found exceptional CEOs and board members who have done a great job transforming the airline to what it is today. They have been smart, innovative and open to opportunities as they have presented themselves to run an efficient business.
