Green Party co-leader Russel Norman says there is 'absolutely no deal' with Kim Dotcom over his extradition case.
The prime minister claims Dr Norman has been secretly meeting the internet entrepreneur to discuss his extradition case and the political party he is forming.
Dr Norman has acknowledged visiting the Dotcom mansion twice last year, but told Morning Report it was only to discuss the internet economy and the Internet Party.
He said the visits were above board and no donations were offered or accepted.
Dr Norman said he has always been highly critical of the Dotcom mansion raid, which was illegal.
He said there is nothing underhand in his statement that if involved in the next Government, he would fight Mr Dotcom's extradition to the United States.
Winston Peters is refusing to confirm or deny the Prime Minister's claims that he has been to Mr Dotcom's house three times.
John Key said both MPs should provide details of what they talked to Mr Dotcom about.
He said both he and ACT MP John Banks were pursued relentlessly by opposition parties about details of conversations they had during the controversy over Mr Dotcom and the Government Communications Security Bureau.
