New Zealand First leader Winston Peters has again used parliamentary privilege to grill United Future leader Peter Dunne on leaking official documents.
In a select committee discussion on student loans this morning, Mr Peters asked the Mr Dunne, the Revenue Minister, whether the Inland Revenue Department prioritised and enforced privacy.
"Would any leak that [came] from the department be seriously investigated?" Mr Peters asked.
Mr Dunne said that the IRD had not dealt with any leaks of information, but if it did, it would be rigorously investigated.
He said that Mr Peters' questions about leaking information to the media were "speculation".
