I've yet to see such a beast as a Mount Cook/Freedom pilot on Air NZ senority. There ain't such an entity. Remember that Mt Cook is Link as well.
Freedom yes. Mt Cook, Nah!
That rumour refers to, I think, any regional jet over 70 seats. And as far as I've heard, not in any Air NZ contract. I could be wrong.
Re the TPC thingo, it didn't make a lot of waves outside alpa house then. The few I've talked to didn't seem to jump on a high horse. Maybe they'd all been beaten up too much. Or looking for a length of rope.....
Whatever.
Like I said b4, get your job and be happy. Join or dont join. Your call. Just don't bag it to those that like the benefits (& aren't card carrying .......)....
But if you want change then put your hand up to do something about it!
