Hi,

If you get permanent residency, and then decide to adopt a child from outside of New Zealand, you may have great difficulty sponsoring the childs residency.

It's probably best to adopt the child first, and then include him/her in your application as a family.

If you plan on going the first way, I would recommend that you contact the NZIS about it first as I'm not too sure about adoption proceedures.

All the best
