SIS has undergone drastic changes since mosque attack but isn't 'all seeing'

New Zealand’s Security Intelligence Service (SIS) has implemented significant operational reforms following the 2019 Christchurch mosque shootings. Despite these structural adjustments, officials emphasize that the agency does not possess omniscient surveillance capabilities. The ongoing public discourse surrounding these changes was recently reignited by the publication of a book investigating the tragedy. This literary work suggests that critical intelligence failures and missed warning signs may have contributed to the inability to stop the attacks. Consequently, the agency continues to navigate the balance between national security requirements and the limitations of its preventative reach.

The report highlights the persistent tension between intelligence agency oversight and the public's demand for accountability regarding the prevention of domestic terrorism.
