The spy agency took two years to implement a major shift in how it targeted threats, but once it did, the rewards were almost immediate. The Security Intelligence Service (NZSIS) got 10 leads on right-wing extremists in the lead-up to the Christchurch mosque attacks. This came within a few months of the SIS shifting from an overriding focus on Islamists and threats it knew about, to looking much harder at ones it did not, notably white supremacists. Summaries of its strategies - newly released to RNZ under the OIA by the SIS - alongside the Royal Commission of Inquiry reports, show how that vital shift was a long time coming, held back by what the commission called "scarce" counterterrorism resources - though an internal review, the Arotake report, maintains the agency got its priorities and rebuilding right.
