New Zealanders were also more likely than Australians to browse the web, stream videos, check their email and the news and download music.
That use was despite 61 per cent of New Zealanders having concerns about their online privacy. But in Australia, 67.1 of those interviewed expressed privacy fears.
When it came to social media use, Australians were more likely to log on using their smartphones, but Roy Morgan Research NZ general manager Pip Elliot said that may change.
"With the new iPhones 5S and 5C due to land in the next few weeks, it will be interesting to see whether more New Zealanders hop on board the smartphone juggernaut."
Kiwis also outdid Australians when it came to online spending.
Nearly half of New Zealanders (47.5 per cent) aged over 14 bought something through the internet in an average month, compared with 35.4 per cent of Australians.
Research showed our neighbours had adapted to 3D and flatscreen TVs, e-readers, laptops and tablets more quickly than New Zealanders.
While 30.2 per cent of Kiwis owned tablets and 10.4 per cent owned e-readers, those numbers were 42.1 per cent and 13.1 per cent in Australia.
