Speaker David Carter has asked the Privileges Committee to draw up rules setting out the circumstances under which information such as security access details can be released, after concerns were raised that such details were used without permission to track the movements of United Future's Peter Dunne and Fairfax reporter Andrea Vance.
Parliamentary Services released swipe card details of Mr Dunne and Miss Vance to David Henry as part of his inquiry into the leak of a GCSB report to Miss Vance. The details allowed Mr Henry to trace some of their movements through Parliament.
Mr Carter dismissed a complaint by Green Party co-leader Russel Norman against the Prime Minister over the issue, but said Dr Norman's complaint did raise serious issues that the Privileges Committee was best-placed to look into.
"The exercise of intrusive powers against members threatens members' freedom to carry out their functions as elected representatives and the House's powers to control its own proceedings and precincts without outside interference.''
He said the release of information relating to journalists working in Parliament also raised concerns.
