Labour has called it the Parliamentary equivalent of spam mail but National is unrepentant about lodging more than 6000 written questions to ministers in the past month.
Opposition MPs can lodge written questions to ministers, with the answers then published online. Since Labour came to power National has lodged thousands, with many asking what meetings a minister held on a specific date.
National's Leader of the House, Simon Bridges, acknowledged a "side effect" of that approach would be to test the new Government and its staff.
"Is part of this around testing the Government more broadly and is that a side effect of what we are doing? Okay, maybe. But the primary reason for doing this is to get substantive answers on what they are doing at this stage of their Government so we can understand their priorities.
"We are not getting answers inside or outside of Parliament. That necessitates us asking more detailed and specific questions. If we were getting answers to what we feel are reasonable questions, we wouldn't have to ask so many."
