I am not sure if this will help. Well i am currently on my last year of my bachelor degree in Massey university (New Zealand)

As much as i know theres many scholarship and students supports in New Zealand. For example Student Loan is pretty easy to gain if you have the right requirements.

maybe it will be best if you talk to one of New Zealand university's representative.

As for living cost, its really depend on where you lived. If you would like to know more about career in New Zealand please check on this website
