Do research-oriented courses require publishing a research paper, and what if my previous research paper was rejected in New Zealand for a Master's?

No, research-oriented Master's programs in New Zealand do not require you to publish a research paper. You are expected to complete a thesis or research portfolio showing your ability to conduct independent research, but publication is not mandatory.

If your previous research paper was rejected, it will not negatively affect your application. Admissions committees focus on your academic record, research skills, and how well your background fits the program. Your strong qualifications and extensive work experience in Pharmaceutical Sciences will be valuable for your application.
