NZ Aus living
Up till about 15 years ago CER - Closer Economic Relations gave you the previledge of moving between Aust and NZ with out dealing with costly migration checks. Then the Aust Govt got stingy and changed things. Reciprocated by NZ govt.
I made inquiries some years ago on moving to NZ as a had an NZ born grand parent. Answer was no go. Strange because if she had been a limey then I would have been able to get an EU passport and migrated to the UK.
Cannot even blame little Johnny for this one as I think it was Paul Keating that changed things for the worse.
