Asked later about the endorsement, Mr Peters said he had not heard it but that Rowles was clearly an astute man.
Mr Peters said he believed the party could get 190,000 votes this election - double the number it received in 2008 when it just missed out on getting back into Parliament.
Mr Peters did not reveal which electorate - if any - he would stand in, despite speculation he would try to reclaim Tauranga to tap into discontent with the Government since the grounding of the Rena.
He said that would be announced tomorrow, when the final nominations were due.
Candidates include former North Shore Mayor Andrew Williams, former weather broadcaster Brendan Horan, former NZ First MPs Pita Paraone and Barbara Stewart, and Dr Hugh Barr, a scientist who opposed National's overhaul of the foreshore and seabed legislation.
Mr Peters likened National and Labour to rugby balls: "You never know which way they'll bounce next."
