New Zealand admits it has access to Facebook takedown portal to censor content
New Zealand has always had an official censor (Office of Film and Literature Classification [1]), responsible for what works are available in the country.They already have an internet filter which blocks access to certain domains/ip ranges/etc. [2]Of course they would require similar abilities once Facebook came to their notice by broadcasting a terrorist's murder spree. [3]It would have been "You are selling to New Zealanders. 
We will have the ability to censor information passed to NZ IP addresses, or we will block the IP range, your choice."[1] https://en.wikipedia.org/wiki/Classification_Office_(New_Zea...[2] https://en.wikipedia.org/wiki/Internet_censorship_in_New_Zea...[3] https://en.wikipedia.org/wiki/Christchurch_mosque_shootings
