Schools blocked 300,000 attempts to access pornographic websites in a single month this year.
Ministry of Education associate deputy secretary Pauline Cleaver disclosed the figure for the month of March at a parliamentary committee hearing today on a petition by two Wellington High School students for better sex education in schools.
"We have heard from parents and young people about the increasing curiosity of young people at increasingly young ages," she told National MP Nikki Kaye during the hearing.
"We know that school sites are blocking, we know in one month that 300,000 searches were blocked from our school network. That tells us that children are curious, that they are seeking access.
"It tells us that safeguards and blocks are in place, but it means that we have to have community, parents, whānau and teachers feeling confident and skilful enough to have conversations about the harmful effects of pornography.
