I feel something is missing from the story too. Perhaps the OP is also unaware of the full facts.
I doubt the media tweets will get a response, as the scenario seems so implausible.
I did a quick scan of the RBNZ website and nothing shows a maximum deposit rule.
It just simply does not make sense to me, 2 willing parties wanting to do business and the government stepping in for no good reason.
Although, I've got an open mind. I've been convinced of the rights/wrongs of a scenario before, then something comes up that you hadn't considered which changes things.
@surfisup1000 I hope you are correct and it seems so implausible to me and my family / friends as well
