Am I eligible for postgraduate studies if my prior education is not in the same field in New Zealand?

Yes, you can apply for postgraduate programs in New Zealand even if your previous education is in a different field. Many universities offer "conversion" Master’s degrees or graduate diplomas designed for students who want to shift to a new area. With your four-year bachelor's degree in Arts, a passing grade of 45%, and substantial work experience, you may be eligible for these programs. Your PTE score of 65 also meets English proficiency requirements for most universities.
