Hello dear student,

As it seems like you want to take admission in New Zealand. so dear student it depends in which university you want to take admission in , so different universities asks for the different exam .They all have  their own criteria to take students for MS in their university. So maximum universities asks for GRE marks while few asks for the other test scores.  GRE though not too popular, GRE is required for admission to masters courses in some of the universities in New Zealand.  GMAT: While NZ, just like Australia puts more emphasis on work experience, GMAT is still accepted for admission to management courses in its business schools.

i hope it was helpful.

Best wishes
