Facebook has broken its silence over the Christchurch terror attacks by unveiling plans to combat hate speech.

In a letter provided to the Weekend Herald, the platform says they're looking into restricting access to Facebook Live and are working on banning hate groups, including ones within Australia and New Zealand. 

They also plan to build better technology to identify violent videos and images.

However, technology commentator Paul Brislin is less than convinced.

He told Lorna Subritzky that this is very "light weight, entry level" plans, and it's too little and too late.

"This isn't the first time that FB Live has been used to live-stream atrocities as they happen. Three years ago, a man was shot dead in Ohio live on Facebook. They promised then they'd do something to change it... and nothing's changed." 

Brislin believes that Facebook does have the technology and the ability to properly monitor this level of content, as they currently do it for Germany. 

"The laws are very strict around far right and Nazi discussion. They do it for Germany. If you want to clean up your Twitter feed, I'd go into your settings and change your location to Germany and 90 per cent of the hate speech disappears."

He says that the only way that Facebook would listen will be if there is legislative pressure from governments around the world.

Brislin wants that pressure to be felt by all social media companies, as Facebook is not the only problem.

"If you find something horrible on YouTube, next all your recommends videos will be 'Do you want to look at this atrocity?'"
