It would seem to me that because of clause 27, the answer is going to be emphatically fewer, because no production company would come into New Zealand with a big budget and a chequebook to write for these contractors if before they even start the conversation about "Are we going to engage with each other?", they're under a legal obligation to conclude that bargaining with a contract. They're just not going to take that risk. And actually, they're over a barrel before the negotiations even start.
