Clips from the terrorist’s video of the Christchurch mosque attacks were uploaded last week to Twitter, which did not pick them up as harmful.
Other users reported the videos and the government separately raised it with the company on Friday night.
A spokesperson for the Prime Minister said Twitter’s automated reporting function failed to identify the content as harmful.
Twitter advised the government overnight on Friday the clips had been taken down and it would do a sweep for other instances.
