National's being accused of spamming Parliament, its MPs lodging more than 6000 parliamentary questions in the last month.

Nearly 6300 questions have been submitted, with the majority asking what events or meetings a minister had attended on a particular date.

In contrast, Newsroom says only 964 were submitted by the Labour-led Opposition in the month following the 2014 election.

Labour Leader of the House Chris Hipkins says the Opposition's got its priorities wrong.

"What we've seen from the National Party in the last few weeks is the parliamentary equivalent of spam mail, and as a result I don't think they're going to get much useful information out of it," he told Newshub.

Shadow Leader of the House, National MP Simon Bridges, says so many questions are being asked because Labour's not giving them good enough answers.

"We're not getting answers in Parliament or outside of it from new ministers. If they answered our questions… we wouldn't have to ask so many," he told Newshub on Sunday morning.

"We have a right to ask questions, we have a right to get answers. We're not getting them at the moment, and that's leading them to yet more while we try and work out how we can get good answers to these, we think, reasonable questions."
