Hi Silvie
Welcome to the forum.
Getting a job in NZ is easier if you are there because potential employers seem to like to see applicants on a face to face basis and, of course, you are more attractive to them because you are already in the country and not just thinking about it. It shouldn’t be too difficult to find a job with your skills and it shouldn’t make any difference that you are Asian as there are many Asians working in NZ already. There may be the odd one or two employers who prefer to hire Europeans or Americans, but that’s their loss.
Do you know if your qualification from Secretary Academy is recognised by NZIS? This is important because the number of points you can get for a qualification and work experience is what helps you to be accepted for Permanent Residency. Also if your job is a managerial type position that will help because those jobs are on the skills shortages list. It’s a good starting point.
Once you find out if you qualify to apply for PR, you will know which way to go. If you don’t have enough points, the next best thing is to find a job and apply for a Work Permit. This is not a permanent solution because the WP is only a temporary measure and will not get you PR. You can, however, extend your WP when it runs out. You can get WPs from 1 – 3 years so having one will allow you to stay in NZ for up to 3 years, then you can apply to extend.
