Gareth Morgan's brand new political Opportunities Party is yet to release a policy, but has around 1000 members already.
The left-wing party received the amount of financial members needed to register the party in less than 24 hours after its launch.
Chief of staff Geoff Simmons says it's a good sign and it shows people are clearly into what they've been talking about.
"We really want to keep building as much support as we can before March, when we'll make the call whether or not to contest the election.
"Over the next few months we'll be releasing policies and seeing how the public reacts."
The Opportunities Party has been launched in a bid to push away from establishment and career politicians.
Mr Simmons says they're surprised and humbled by the support.
"It's a great start for us. Clearly there is an appetite out there for doing politics a little bit differently, and moving outside the establishment, career politician-type system.
"We're glad to have tapped into that."
The party will be releasing its first policy in December and is keen for members to keep signing up.
