Congressman Chambliss also said that American terrorism experts had been visiting countries on the list and hoped to come to New Zealand.
Communications staff at the US State Department said a comprehensive report - Patterns of Global Terrorism - released by the department in April made no mention of New Zealand.
An FBI spokeswoman told the Herald that she had no knowledge of New Zealand appearing on any list of countries containing terrorists and if it did exist it would not be made public.
"I haven't heard of the list. If there were a list the appropriate authorities would probably be notified."
Congressman Chambliss' office was unable yesterday to find the source of his information.
The congressman himself was unavailable for comment.
The Weekend Herald revealed in August last year that police had investigated signs of an Afghan cell in Mt Albert suspected of conspiring to attack the Lucas Heights nuclear reactor in Sydney.
