actually it would be pretty easy to guess your race. just a quick check of most common native and immigrant groups for new zealand. that'll probably rule out 99% of the worlds population because it's such a isolated country.
but still, why you're ashamed i dont know.
maybe you're a gypsy? must be something that people have prejudice about in general and you'd like to avoid the drama and the negativity that comes with it.
Give it a shot. You'll never succeed however, cause the first thing you'll find out is that Auckland has people of all races living in it. And I mean all races.
I'm not typically representative of my race. I don't take pride in something that metaphysically happened to me over which I had no control. I pride myself on what I've made of myself, with conscious choice and effort.
I am literally, 1 in 6 billion.
And so are every one of you!
