Former Tauranga MP Bob Clarkson has rejected two approaches from leader Don Brash to stand in November's general election for the Act Party.
Mr Clarkson, who has crossed from National to Act, said he thought about standing in the Tauranga electorate but decided against it.
"Don Brash has had a couple of cracks at me, even on the weekend, but my wife would kill me if I stood," he said.
National candidate Mr Clarkson rolled New Zealand First leader Winston Peters by 730 votes to become Tauranga MP in 2005 - after Mr Peters had held the seat for 21 years.
Mr Clarkson then stood down for the 2008 election, allowing Simon Bridges to take over.
