That's good - I was imagining the delays there could be if she had been the main applicant, and hadn't yet gone into the formalities necessary to be a teacher in NZ.
Right - if your wife wants to be a teacher, she will need to have her qualifications checked by, and register with, the New Zealand Teaching Council.
http://www.teacherscouncil.govt.nz/c...rseas-teachers This page and the links off it give all the requirements. I hear from other teachers who are members of the forum that, in case of any questions, you can contact the NZTC through their website, and the people there are very helpful.
