Whether you can work here after your MBA depends on whether you get a job. At the moment, all NZ graduates a granted a 6-month work visa on application. If you do get a job within six months, they'll grant you a permanent work visa. I believe the job has to be full-time and related in some way to your course (with an MBA that should be too difficult to comply with). Once you find a permanent job and work for about 2 years, you'll be able to apply for PR. Then you can work full-time/part-time/ not work while you study... what ever suits you.

If you don't go down the job/PR route but instead start your PhD immediately after your MBA, you'll be on an international student visa which only allows you to work up to 20 hours a week. Note that PhDs students are only charged local fees.

I'm sorry, can't tell you much more than I already did. For the MBA/IT/related to degree thing, you'll have to check with NZ immigration.

PhD fees are around $4000 per year. Before the govt implemented this policy, it was at least 3 times more. It varies from course to course though, more technical courses are more expensive. You'll have to find out the exact figures from the unis. You could always try looking for scholarships too.

NZ academia - I have no clue how hard it is. general tutorship positions while pursuing postgrad degrees aren't hard to get, but full-time positions are different. I suppose it depends on which institution you go to and whether there are vacancies. Standards are generally high since we don't have hundreds of private colleges here. They are equal opportunities recruiters, which basically means that you won't run into racism problems getting a job.

There are 3 different campuses for Massey, not sure whether where the business faculty is located. The main campus is located at Palmerston North, whereas the other 2 are in Wellington and Auckland. Not too familiar about Waikato though.

But why limit your choice of universities in NZ? Why not consider UOA or Otago even?

for master in engieering or CS, it will be RM100k for a year though hahaha clear my pocket in KWSP account B in 1 shot.... for phd, it can tahan for 2 years. Sure, a teaching assistant income is crucial there if study phd...my wife is quite hesitate for me to do that though coz of let go of malaysia income and go there she has to afford the family while i can barely survive on my own with the teaching assistant job.... decision! decision!
