New Zealanders who die or leave the country completely are being replaced by residents of other countries, as immigration modifications the face of New Zealand's society and workforce.
Between 1964 and March this year, 942,300 New Zealanders left the country completely and 1,101,600 residents of other countries migrated here.
Richard Bedford, a professor of population geography, stated net migration was changing the face of New Zealand society "as varieties of births fall while deaths rise in an ageing populace".
Teacher Bedford stated Auckland was most impacted because while New Zealanders returned and left from all areas, other residents "mainly move into and out of Auckland".
Census data launched last week exposed the New Zealand populace grew by 214,000 since 2006.
Professor Bedford stated natural increase, as opposed to net migration, still stayed the most essential aspect for populace development.
The average number of births has to do with 60,000 every year while there are about 30,000 fatalities.
However "churning" - the procedure of citizens of other countries changing New Zealand residents - indicated the migrant workforce was of growing importance to the economy.
"Churn is most significant amongst the age most likely to move, 20 to 40 years," Professor Bedford stated.
Statistics New Zealand figures also showed that in between 2008 and 2012 there was a boost of 81,100 in the workforce who were not New Zealand-born.
Of the 583,300 overseas-born employees, who formed 36 per cent of workers last year, 331,600 were not recent migrants however had actually lived here for even more than 10 years.
Edwina Pio, professor of variety at AUT University, stated she anticipated the number of minority ethnicities to have increased considerably between the 2 Censuses.
Demographic changes suggested New Zealand employers should make radical changes to the way they viewed using migrants.
Multicultural development required them to make "seismic changes in their views towards utilizing and progressing ethnic minorities in the workplace", said Professor Pio, who is also an associate director of the NZ India Research Institute.
"Employers will have to discover how you can manage diversity in the workplace and to see this as a perk as opposed to a deficit.".
Massey University sociologist and immigration specialist Paul Spoonley said the international monetary crisis reduced the variety of immigrants showing up and contributed to the number of New Zealanders and immigrants leaving, especially to Australia.
"In five of those seven years, we had major net losses to Australia ... it looks as though the net loss had to do with 150,000, so that influences the net gain/loss for New Zealand as a whole," Professor Spoonley stated.
If the high number of overseas-born workers showed companies below were now more accepting of migrants, it was hard to know.
"Remember that numerous even more of our employers are themselves immigrants who then utilize other immigrants," he said.
Stats did not address the "genuine concerns" about the nature of this employment, wage levels and if the jobs mirrored the qualifications and experience of immigrants.
