White supremacy
Following the Christchurch mosque shootings in March 2019, the GCSB assembled a 24-hour operation response team which worked with domestic agencies and foreign partners to support the New Zealand Police and its domestic intelligence counterpart, the New Zealand Security Intelligence Service. In December 2020, a Royal Commission of Inquiry into the mosque shootings criticised the GCSB and other security services and intelligence agencies for focusing on Islamic extremism at the expense of other threats including White supremacy.
