Kiwis almost never look for pornography on the web, a survey partly conducted by AUT University has found.

The survey of 1250 people in 30 countries showed that fewer than 5 per cent of Kiwis admit using the internet for pornography daily. More than 80 per cent said they never looked for sexual content on the web.

AUT professor Allan Bell said the result should be taken with a grain of salt and Netsafe executive director Martin Cocker agreed that people "massively under-report" pornography use.

The survey showed web use up among older people: more than half of over-70s and a third of over-80s access the net at home.
