Will there be difficulties pursuing a PhD from here compared to pursuing a double master's abroad in New Zealand?

It depends. You can pursue a PhD in New Zealand after your current master's in India, but there may be more challenges compared to doing a double master's abroad.

- PhD admissions in New Zealand usually require a master's with a strong research component. If your Indian master's did not include significant research, you may need to show equivalent experience.
- Double master's abroad programs often provide structured research training and international recognition, which can make PhD admission smoother and help you build connections with potential supervisors.
- Networking and supervisor fit may be easier if you study abroad first, as you'll have direct access to faculty and research opportunities.
