Cos you've been over there since you were about three, if I'm not mistaken.
7 actually, although I guess not much difference. Have just always felt English and preferred to support England and Britain in sports etc. Possibly to do with the all teasing about being a "pom" and "go back home" when I was first in school here and my parents also found people to be very anti-English at first. My Dad says it's probably made him much more patriotic of England than he ever was when he lived there. Have also never taken NZ citizenship so am not legally an NZer either.
