More Australians are making the one-way trip across the ditch than Kiwis going the other way for the third month running.
Before April 2015 there had not been a net inflow of Australians moving to New Zealand to live and work since 1991.
But for the third month in a row, the historical trend of New Zealanders heading to Australia chasing higher wages and conditions has been reversed.
The latest New Zealand government figures show that in June, it had a net inflow of 100 Australian migrants.
Australian arrivals rose 9.2 percent to 24,100 with two-thirds being New Zealanders returning home.
India was the third-biggest source for long-term arrivals with 13,300 in the year, a 61 percent increase from 2014, while China was the fourth largest with 10,300, up 16 percent on the year. UK arrivals fell 2.3 percent to 13,500.
The arrivals was a part of a record annual net gain of 58,300 new migrants for the full-year to end of June 2015.
Meanwhile, short-term visitor arrivals rose 9 percent to 177,000 in June from the same month a year earlier, led by gains in Australian, Chinese, and American visitors. Short-term arrivals rose 7.4 percent to 2.99 million in the year.
