Cheering British and Irish Lions fans helped bring a surge of overseas visitors into the country last month, while net migration also reached a record high.
With the Lions touring to play the All Blacks, 23,400 UK and Irish visitors flocked into the country in June, up from 16,700 in the same month last year.
It was the second highest month for visitors from the two countries in New Zealand's history, Stats NZ population statistics senior manager Peter Dolan said.
"The highest was in June 2005 when arrivals reached 28,200, which also coincided with [a] British and Irish Lions tour to New Zealand," he said.
