The SIS yesterday launched a website so the public can confidentially and anonymously pass on sensitive information.
SIS director Warren Tucker acknowledged there was potential for the system to be abused.
"However the majority of people who volunteer information to the SIS are genuinely concerned members of the community. The people receiving this information are trained to follow a process that mitigates the risk of pursuing false or malicious information."
The SIS has about 200 staff and advises the Government on matters relating to New Zealand's security, including investigating threats to security and disrupting them if necessary, and gathering foreign intelligence.
