In May, Jacinda Ardern co-chaired the 'Christchurch Call' summit, where she and French President Emmanuel Macron addressed the spread of extremism on social media.
But replies on Twitter to the alleged Christchurch gunman and video which he shared, cited by Stuff Circuit documentary Infinite Evil, are still online.
YouTube reportedly only took down footage and channels after it was approached.
According to Infinite Evil, the comments sections of the videos and Twitter replies enticed racism and far or alt-right ideologies.
Last week, NZME revealed a Ukrainian online message board was selling the alleged gunman's manifesto in paperback form, reportedly for NZ$6.23.
The document was published online just minutes before the alleged gunman attacked two mosques in Christchurch, killing 51 people. It was banned by the Chief Censor earlier this year.
According to NZME, the administrator of the "Ukrainian right-wing" channel it's being sold on wrote: "The idea is to give paper versions to everyone in a row, on birthdays, wedding anniversaries and baptisms of children".
