Firebrand MP Hone Harawira is gearing up to launch a new political party to contest the November general election, this weekend.

The 'Mana Party' is expected to be officially launched on Saturday.

Left wing political pundit Matt McCarten has been lined up as party president and ex-Green MP Sue Bradford and lawyer Annette Sykes are on the list of potential candidates he hopes to woo, Newstalk ZB reports.

The party has yet to decide how many seats it will contest, or whether it will concentrate on his seat and winning party vote, Mr Harawira said.

He said the Mana Party moniker would not last and a permanent name would be decided in a competition.
