In response to the 15 March 2019 Christchurch mosque terror attacks that killed 51 and injured 40 people, New Zealand’s government-owned investors, supported by 105 global investors representing approximately NZD$13.5 trillion, began a collaborative effort to engage the world’s three largest social media companies (Facebook, Alphabet and Twitter) to strengthen controls to prevent the livestreaming and dissemination of objectionable content.

That engagement has now concluded with the release of an independent external research report, which examined whether changes made by the companies are appropriate for the scale of the problem. The research also took a look into the different types of emerging regulation on this issue.

The research was undertaken by a New Zealand based consultancy Brainbox Institute, which specialises in analysis of issues at the intersection of technology, politics, law and policy.

Brainbox found that the measures put in place by the platforms are likely to be highly effective in mitigating the scale in which objectionable content of a similar type to the Christchurch terror attack, can be disseminated online. It also noted, however, that it is unlikely the platforms will be able to entirely prevent a similar type of incident in the future.

Conclusion note on the collaborative engagement

Announcement to mark the end of the engagement

Our thoughts remain with the victims of that horrific act. May they rest in peace.



More than one hundred investors representing approximately USD7.5 trillion of assets-under-management* have joined a global collaboration to encourage Facebook, Alphabet and Twitter to strengthen controls to prevent the livestreaming and dissemination of objectionable content. The initiative will continue to accept new signatories until these companies take meaningful action.

20 March 2020

Dear Board members and executives of the social media companies:

Almost exactly one year ago, 51 people were killed by a gunman in two mosques in Christchurch New Zealand while they worshipped. It was an act that was livestreamed and disseminated across your respective platforms. Our hearts remain with the victims, their families and loved ones and all those affected by this horrific act.

This investor collaboration has made its voice known to you over the year since the atrocity in Christchurch. As owners of your companies, we welcome the changes you’ve made to your platforms and the industry collaboration that has occurred via the Christchurch Call. Mass shootings have, however, continued to be disseminated across your platforms, including via livestream (for example, the recent mass shootings in Thailand and Germany). They remain open to abuse.

It is time that your respective organisations acknowledge the influence you have within society and embrace the responsibility that comes with this. 

Our request includes:

  • clear lines of governance and accountability for senior executives and Board members to ensure your platforms cannot be used to promote objectionable content like the livestreaming and dissemination of the Christchurch shootings; and
  • sufficient resources being dedicated to combating the livestreaming and spread of objectionable material across your platforms.

We encourage and expect modernisation of legislation to protect the public from exposure to similar content in the future. Policy must be built on robust evidence and for this we need you to be open about how your platforms are built and operated.

Perpetrators of crime cannot be permitted to weaponise their actions via your platforms.

To date, we have been dissatisfied with the response from your senior executives and Boards to us. The failure to respond to these actions creates a significant business risk, beyond the harm caused to the global community. You have a duty to address that. We remain open to continued engagement. Our expectation is that you will take responsibility for and fully address this issue. 

Yours faithfully,
