German-born internet entrepreneur Kim Dotcom, who is awaiting a US extradition hearing on charges of internet piracy, tweeted a photo of the new party's logo on Wednesday.
The United States has charged the co-founder of file-sharing website Megaupload and three colleagues with internet piracy, money laundering, and racketeering.
Dotcom earlier said that the party would campaign for fair internet pricing and no internet data caps.
As a permanent resident of New Zealand, Dotcom is not eligible to stand for parliament, but is able to be president of a political party.
Dotcom also will launch his online music service Baboom and release his debut music album Good Times on Monday.
