New Zealand has a large economy that requires an extensive workforce. This, combined with a relatively small population, means New Zealand can't rely on its own people alone to get the work done, so New Zealand is dependent on expatriate workers to help sustain some of its industries. Added to this is the propensity of Kiwis to become expatriates themselves – New Zealanders are second only to the Irish in terms of the expatriate diaspora in the developed world. Currently, approximately 1 million New Zealanders, around 14%, live overseas.
