Colin Craig has launched legal action against Greens co-leader Russel Norman, over remarks Norman made about Craig at Auckland's Big Gay Out.
Fairfax understands Craig's complaint relates to Norman suggesting Craig thinks that a woman's place is in the kitchen and a gay man's place is in the closet.
Norman made an almost identical comment in Parliament during his opening speech for the year, but attributed it to the "conservative right," rather than Craig himself.
A spokeswoman from Craig's office confirmed legal action had been launched.
Craig's lawyers had sent a letter to Norman, demanding an apology and retraction to an audience similar in size to the one that heard Norman's original comments.
His lawyers said further action could be taken if no such apology and retraction was received.
Norman was yet to respond publicly over the legal action but was in discussions with his own camp over it.
