Right, but that's not the point. You even said yourself that you didn't include her to speed up the process -- your wife's PR was issued on the basis that she had two dependents when the reality is that there are three. That's all there is to it. Don't get me wrong, the situation you are in SUCKS, but it still remains that what you did is immigration fraud as the forms are quite clear that everyone must be declared. This forum is hosted by an immigration firm, their number is around here somewhere. Though they are based in Canada, wouldn't know where to start for someone in NZ. Good luck to you.
