Maori Party whip Te Ururoa Flavell says his caucus has undersold itself during the election campaign.
He says it has failed to get across the message of what the party has achieved and the hard mahi still being done.
Mr Flavell says one example is the Maori Party securing a Government review of how well taxpayer money is spent on developing the Maori language.
He says the report is still in progress but hasn't received much attention.
Mr Flavell, who is the sitting MP for the Maori seat of Waiariki, says more MPs in Parliament would help put the Maori Party's achievements in the public eye.
