Hone Harawira's Mana Party has been registered by the Electoral Commission on the eve of the Te Tai Tokerau by-election.
Mr Harawira was late with his application to register the party, which raised the possibility that it wouldn't be registered in time.
That would have meant that the party was not recognised under electoral law.
The commission said tonight it had considered whether the name of the party could confuse voters, because there is an electorate called Mana just outside Wellington.
"The board has concluded that although there is a remote possibility of confusing or misleading a small number of electors in the Mana electorate, this falls short of the statutory test for refusal of registration of a political party," it said.
