Hi. You sound like you have lots of opportunities in NZ. To get a job as a doctor, your wife would need to obtain provisional registration with the NZ Medical Registration Board - see
https://www.mcnz.org.nz/home/doctors...n-new-zealand/. If she obtains this, she do not have to an Individual Qualification Assessment from NZQA. She can then either apply for jobs and then go for residence when you get one or see if you have enough points (140) without a job offer. See
http://skillshortages.immigration.go...paediatrician/. The job isn't on the Long Term Skills Shortage List, but it is on the Immediate Skills Shortage List - which mean that getting a work visa is much easier (but it doesn't help for residence. As a software developer, your job is on the Long Term Skills Shortage List, but if your qualifications are from Brazil, you will have to have them assessed by NZQA - see
http://www.nzqa.govt.nz/qualificatio...ns-assessment/. Hope this helps to get you started.
