The Opportunities Party also rated 1 per cent in the latest 1 News Colmar Brunton poll on party vote, which could mean three MPs with an electorate.
Winning an electorate seat means a party does not have to reach the five per cent threshold before getting MPs.
Morgan, a millionaire economist and author, launched his party this year but has not decided whether to stand in an electorate or just stand on the party list.
A party source said tonight Morgan was actively considering the Epsom option partly because of the Herald ZB poll.
Among the party's radical policies are cutting superannuation for the wealthy, giving an unconditional allowance of $200 a week to young people, parents of children under three, legalising and regulating cannabis, and applying tax to all productive assets including housing and land.
Morgan has locked horns with New Zealand First leader Winston Peters and expressed concern at the prospect of him holding the balance of power after the election.
