there IS a cure, only I doubt that the industry has the guts to do it: go on strike, Kill everything from remote area tourism flights to the King Island crayfish trade. No exceptions. Stop the medical emergency flights as well. Shut it all down until there is a binding agreementf from both sides of Government to break up CASA and separate the roles of regulator and policeman, give ATSB back its full independence and implement the NZ version of FAA regulations.
Nothing less is going to save you. Creampuff is right, neither side of Government responds to rational argument. Kick them both in the balls if you want a result.
....or perhaps build a fighting fund and donate massively to both their political campaigns, they seem to be getting as greedy and corrupt as American politicians.
