Just checking NZ's calculator again, AU GSM is by far easier if you compare side by side, and if you see the trends in the past stats, but NZ is more straight forward, walang maraming types ng visa and have easier qualifications assessment - may exceptions sila sa mga recognized schools from PH which is in fairness marami rami.
For NZ's EOI, wala kasi sa calculation nila ang English competency, requirement lang siya to be eligible pero di siya makaka affect sa EOI score so nabawasan ng area na pwede sana nating pataasin. Pero check mo rin since may partner ka, may points to sa EOI. For singles kasi wala.
