Mr Dotcom triggered a flurry of speculation in recent weeks after claiming that a sitting electorate MP had agreed to join his party. While he refused to say who it was, he ruled out Mr Harawira.
Today the party said: " Following the recent decision of delegates at the Mana AGM to continue negotiations with the Internet Party regarding a possible alliance, the current MP and the Internet Party have mutually agreed to end further discussions."
Mr Dotcom said that due to a confidentiality agreement with the MP "no further comment will be made on this matter".
A final decision on whether the Mana Party will join with the Internet Party to contest this year's election is expected in about a month.
