While much of their work must necessarily be carried out in secrecy, I wanted to put on record the work of the New Zealand Security Intelligence Service (NZSIS) and what they did over many years to protect the community from this terrorist. The NZSIS identified the individual in 2016 from his disturbing online activities. He remained a person of interest ever since, with the SIS continually appraising and reappraising the risk he posed. The intelligence collected by the SIS was vital to supporting the Police and other authorities to minimise and manage that risk.
