The Government is working on proposals to keep Kiwis safer online with the tricky task of maintaining freedom of expression.
It comes as a new survey found nearly all New Zealanders believe the content in movies, shows and games can negatively influence children.
New Zealand's worst modern-day atrocity, the March 15 massacre was carried out by a man radicalised online.
Today Prime Minister Jacinda Ardern was in Spain talking up the Christchurch Call, a commitment by governments and tech giants to eliminate violent extremist content online.
"When technology enables violent extremists to bridge the divide between believing harmful false narratives and committing atrocities, the effects can be hugely harmful. We saw this play out tragically in my home."
But three years after the attacks the terrorist's livestream is still around.
Earlier this week the Acting Chief Censor Rupert Ablett-Hampson banned a pseudo-documentary using the footage.
"It's very disappointing."
A new survey of 1000 Kiwis for the Classification Office shows they're particularly concerned about harmful content online.
"We know that many instances of violent extremism have been incubated online," said Ablett-Hampson
The survey found that nearly all New Zealanders believe the content in movies, shows and games can negatively influence children.
Also, more than half of the respondents had seen content encouraging discrimination, terrorism or suicide.
And nearly 90 percent support age ratings and classifying harmful content as illegal.
Respondents said they wanted more regulation of online platforms and stronger laws holding people who create and share content to account.
Others wanted the platforms themselves to be more proactive in monitoring and removing harmful content.
Internal Affairs Minister Jan Tinetti told Newshub she'll release proposals later this year on how to "empower people to stay safe while exercising freedom of expression" on the internet.
Rupert Ablett-Hampson said "there's no easy fix".
A societal problem growing as quickly as the technology that makes it available.
