New research exposes how little parents know about what their kids are getting up to online

Devices can be an easy way to entertain kids - but do you know what they're truly getting up to online?

The answer is probably not.

For the first time, research into Kiwi families by Netsafe has found a big gap between what parents think their kids are doing, and what they're really doing.

The online safety organisation says that comes with dangerous consequences.

Devices can be an easy way to entertain kids - but do you know what they're truly getting up to online?

The answer is probably not.

For the first time, research into Kiwi families by Netsafe has found a big gap between what parents think their kids are doing, and what they're really doing.

The online safety organisation says that comes with dangerous consequences.

Now, in a first-of-its-kind report, Netsafe has compared what parents think their kids are doing online to what's actually happening.

It found 25 percent of children aged between nine and 17 said they had been upset by something online - however, only 19 percent of parents were aware of it.

Netsafe's Martin Cocker says in that area, the gap isn't huge - but he is concerned about other harmful content.

"It's content promoting self-harm, eating disorders, very gory or graphic content," he told Newshub.

"About 10 percent of parents think their kids have seen that kind of content, whereas the actual number is closer to a third."

The research also looked at the number of children meeting a person face-to-face that they met online. Scarily, 38 percent of children were doing that very thing - but only 26 percent of parents knew about it.

Cocker and Lange both have the same number one piece of advice for parents.

"It's about keeping up a conversation with young people about their experiences online," Cocker said.

"Honesty is the best policy," Lange said. "It doesn't matter what happens - you're always going to have their back."
