Can I still enjoy domestic retirement salary and domestic medical insurance after immigrating to New Zealand?

It depends on whether your nationality is China or not. If you only live abroad, you still have China nationality and China hukou, of course you can enjoy it. There is no special rule in the law that you can't enjoy it, but you can't enjoy it if you are an immigrant. In addition, you can enjoy medical insurance, but reimbursement is a problem. It is almost impossible to reimburse unless you come back from seeing a doctor.

However, if you are already registered in New Zealand, you can't enjoy it.
