Initially regarded as part of the "left" group on Council, Ahipene-Mercer has avoided alignment with any faction, preferring to work across all groups. He has fielded some criticism from supporters for his willingness to work cooperatively with right-wing Mayor Kerry Prendergast, but announced in early 2007 his intention to oppose Prendergast in the elections to be held later that year. He told reporters he was "in to win", and if elected would continue to work with all councillors.He was runner-up in the election.
