"For me the objective is to win the confidence of the people of Wairarapa, win the seat and become the MP for Wairarapa and do the best job I can, and we'll take it from there. I'd like people to judge me on my merits, what I've done in the past and what they think I'm capable of, quite aside and apart from my political colour," he said.
"I have a lot of people saying I really need to get back into parliament and fight for the Wairarapa from inside, and that's the conclusion I've come to. I've got some skills and across the parties, across the house, I have a degree of respect. It's about time I put that to use for the Wairarapa.
"And why not, I was born here, bred here, raised here. This is my home. Why wouldn't I want to represent it?"
Mr Mark said he will stand down from the Carterton mayoralty should he win a seat in Parliament despite legislation allowing work in both roles at the same time.
"This is a far nicer environment to work in. I love the fact we have a council made up of people who are not driven by party politics, they are driven by the issues that affect their people. I actually love that. There's a downside of going back in to Parliament. There's a high personal price to pay. But I can't be whinging and whining about things that have happened to the Wairarapa that have not been good for it if I'm not prepared to put myself forward and fight against them."
Mr Mark said he had gained considerable community and civic experience during his four years on council, work with two district health boards, as a businessman, and as a lead treaty negotiator for Ngati Kahungungu ki Wairarapa.
He had also spent two decades in the military and 12 years in Parliament and "hoped people will judge me on my track record".
"I bring a degree of strength and I'm respected by other parties in the house. I'd like to think people will see the value in my career and experience and that I'm the sort of person they want representing the Wairarapa."
NZ First communications advisor Judith Hughey said NZ First's party list was set to be released on Tuesday, the deadline for political parties.
When asked about a draft list that purported to have Ron Mark at No9, she said "there's a lot of gossip going around".
Alastair Scott, National Party candidate for Wairarapa, said voting for Mr Mark was a "wasted vote".
Asked if he would lose votes to NZ First he said "there might be a few".
Labour Party candidate for Wairarapa, Kieran McAnulty, welcomed Mr Mark to the hustings. "This is great news for our campaign. In a three-horse race I have an even better chance of winning," he said. "Mr Mark will take more votes off Mr Scott than he will from me ... The last time there were two right-wing candidates in Wairarapa we ended up with a Labour MP."
