Hi. I am assuming that you are on a SMC Job Search Visa at present (there are quite a few categories in WTR). If you have "an offer of skilled employment in NZ" that is full-time (more than 30 hours a week) and permanent, this should be fine. If the work is skilled and you are working in NZ, albeit for an American company I can see no reason why this would not be acceptable. See the INZ Ops manual SM7.10.1. However, I am not 100% sure, so if I were you, I would send an email to my Case Officer or call into one of the INZ branches in INZ and ask them directly. Good luck! Karen
