RNZ reports Noble MP Lord Vaea says the government has underperformed, particularly when it comes to the budget and changes to the education sector.
Lord Vaea first spoke of a no-confidence motion three weeks ago.
He hasn't officially made a submission but plans to do so next week.
This week the government failed in an attempt to get a two-week adjournment of parliament until some of their MPs returned from overseas.
Mr Pohiva also announced a meeting on education reforms in a last ditch effort to get people on board with the various changes.
