Air NZ management have always been in la la land. Comes from being a protected monopoly. The Govt should never have bailed the incompetent management out after the Ansett Australia shambles. The airline should have been allowed to go under then be resurrected after the inevitable clean out.
Their age old pig-headed management style is rising to the surface again. It started with the swipe at the engineers, they followed that up with a go at the Mt Cook pilots, then the ground staff fiasco. Now it seems Air Nelson overall.
