The Prime Minister’s office said as a member of the Christchurch Call community of 120 governments and online service providers, Twitter was expected to remove terrorist content published on its platform.
Netsafe’s chief safety officer, Sean Lyons, has reminded people they can face criminal charges for interacting with illegal online content.
Lyons said if people saw anything concerning, they should report it immediately to the platform concerned and to the Department of Internal Affairs.
He said the Christchurch terror footage has resurfaced before and can be swiftly dealt with.
Meanwhile, new Twitter owner Elon Musk has tweeted hate speech messages have dropped by a third in the last few days compared with a peak of more than 10 million on 20 October.
