Gareth Morgan, the leader of the Opportunities Party, is said to be considering standing in Epsom against Act leader David Seymour in the September 23 election.
Seymour, a first-term MP, holds the seat with a 4250 majority.
Morgan rated two per cent in the Herald ZB Kantar TNS poll this week which asked: "who do you think is most capable of running the Government?"
However his support was only 1 per cent in Auckland and he polled 4 per cent in Canterbury and Wellington, where he lives.
Seymour did not rate.
