A petition is on its way to Parliament, calling for the Government to take action against pornography.

More than 22,000 people have signed the document asking the Government to look at health and societal harms of online porn.

Labour's Aupito William Sio, who is presenting that petition, told Rachel Smalley pornography is "more prevalent now than ever before".

School councillor Sarah Maindonald said 90 percent of boys under 16 watch porn, which can be addictive and damaging.

She told Mike Hosking teenagers don't always talk to their parents about sexuality so it's time the Government step in.

"They're actually learning about sex from pornography, rather than other sources, and it does really then influence and shape their perceptions of relationships," she said.

Maindonald said better resourcing would help school health programmes tackle the problem.

"Every community will be quite different, there will be religious and cultural considerations. Often the guidance staff and the health teachers are in the best position to look at the appropriate programme."
