The Transport Minister is looking at potentially privatising aviation security at airports around the country.
This comes as the Civil Aviation Authority - which runs the Aviation Security Service - has proposed a 146 per cent increase in passenger safety levies, in the face of a $100 million plus shortfall.
Simeon Brown has put out a discussion document, which includes the possibility of airport security being run by airports, airlines and private security companies.
Mr Brown says he understands the passenger levy needs to rise as it hasn't been reviewed since 2017, but he has ruled out any more funding for CAA from July next year.
The union E Tū represents many aviation security staff - spokesperson Michael Wood, a former Labour Transport Minister, says aviation security is a core regulatory service which should not be privatised to a for-profit organisation.
