In October 2016 New Zealand police, in a "sting" operation code named "Operation Painter", set up roadblocks (checkpoints) outside an Exit International meeting and took down names and addresses of all attendees [REF].
This coincided with another action by New Zealand police in which 76-year old Patsy McGrath, a member of Nitschke's Exit group, had her home raided and her store-bought helium balloon cylinder confiscated under warrant [REF].
