Oh sure, they learned from Erebus and in any case it isn't the same company that it was all those years ago... not even close. However there is still an awful lot of arrogance there in the pilot management side of the company.
I have worked for much bigger airlines than Air NZ, and have not found the same levels of nonsense there at all. It's part of the Kiwi mindset I think (and I am a Kiwi so feel qualified to comment!)
It's a pity, because the product and the commercial innovation is world class - I wouldn't travel with anyone else internationally. Domestically, well I reckon the stage is set for a new player with better equipment.
