I've been living in NZ for 16 years as a permanent resident. Travel on my UK passport. My kids have two passports but generally travel on their kiwi passports. I travel a fair bit, but not really to Europe - only the Uk., Asia, the Pacific and Oz. I am feeling that my passport might be less useful come March and am wondering if I should get a kiwi passport. I would hang onto my uk passport as I don't want to give up my uk citizenship. Any thoughts?
