Two of my moves were for educational opportunities not available at home, the others were for work opportunities.
It's interesting to note that while New Zealand is a similar size to Great Britain, with quite a few million fewer people, we have nowhere near the same number of accents. Other than in the deep south, we've never stuck around in big enough groups in one place for long enough to develop anything other than our wonderful broad Kiwi twang. We are a nation on the move.
Despite all the roaming, I'm one of the lucky ones who has been able to end up back in my home town. But even so, this isn't a huge country and though it may at times feel like it, you're never too far from home wherever you are.
