The party plans to contest next year's election on a list-only basis.
Mr Rintoul said those coming to the party were from all different walks of life who want economic policies that "will help get the country back on its feet".
The policies released so far are something of a grab-bag from across the political spectrum, incorporating some of the philosophy and business-friendly approach of Act with a dose of NZ First's interventionist economic nationalism.
Former National Party MP Ross Meurant, the party's policy analyst who will not be standing next year, said Focus NZ aimed to be the "economic conscience" of the nation.
Like Act, Focus NZ wants to cut taxes, but not in all areas: it wants to introduce a new tax on international financial transactions.
Also unlike Act, it is opposed to asset sales.
However, there is more than a whiff of John Banks' party in Focus NZ's guiding principles which include "reinforce the principles of private property ownership" and "one rule of law for all New Zealanders".
Mr Rintoul says the common theme is that the policies "will get the people we hope to represent being able to compete on the international market".
The board of Focus NZ includes founders Mr Rintoul and co-founder Joe Carr, former Federated Farmers dairy chairman and primary industries commentator Lachlan McKenzie, and Mr Meurant.
