"I had never been [to New Zealand] before we moved here. I accepted the job and thought 'why not'.
"It not only lived up to expectations it's been better than we expected."

"It's not like it has been a jolt. If I had moved from a country town in Australia you'd go 'My God, the prices', but things are similar to Sydney."
Norenbergs said he believed the pay rate is similar in Australia and New Zealand, but the decision to move here wasn't all about money.

If his wife and 10-year-old son had not settled in well in Auckland the family would have moved back to Sydney, but the whole family had made many friends, he said.
"We have made so many Kiwi friends who are just the nicest people."
The change in migration trend has attracted the interest of overseas commentators. Foreign affairs commentator Adam Taylor wrote in the Washington Post this week: "New Zealand has long been overshadowed by its geographically larger and more populated neighbour Australia... complicated by the fact that many New Zealanders moved to Australia in search of jobs and other opportunities."

Statistics NZ figures showed December was the ninth month in a row with a net gain of migrants from Australia. Before April 2015, the last net gain in migrants from Australia had been in June 1991.
Of all migrant arrivals in the December year, 25,300 were from Australia. Fewer New Zealand citizens left for Australia, with departures down 11 per cent to 21,100 in 2015, less than half the peak departures set in 2010.
