No idea. This is my 18th relocation with family and goods. They do not want even to move to another suburb let alone another country, feels like we've arrived now.
So I haven't explored it. In terms of ease for an Indian citizen I still rate NZ and CA to be easier than OZ, UK and definitely the States, in terms of immigration.
But this is my personal opinion and I have many friends in Oz who are happy there.
Maybe if you think you do want to immigrate as a NZ citizen, I suggest look at NZ citizenship if you don't already have it. Oz is not the only place. There are about 95 countries that are very friendly to NZ in terms of immigration.
My writing is fluctuating between Indian English and International. (you don't already have it VS you don't have it already )
