Colin Craig is confident of winning the Rodney seat held by National MP Lockwood Smith after polling put him more than 10 points ahead of Dr Smith's successor, former policeman Mark Mitchell.
Mr Craig, a former Auckland mayoral candidate, yesterday said he would not, as expected, go head-to-head with John Banks for the Epsom seat, but instead had "followed his heart" to stand in Rodney.
"I've lived in Rodney, and my business involvement here has spanned more than 20 years," he said.
"Many of my family live here, and I'm passionate about getting things moving for everyone in the region."
Dr Smith, the Speaker of the House, will stand on National's party list at the November election and former policeman and security consultant Mr Mitchell has been chosen - after a contentious selection process - to stand in Rodney in his place.
