Conservative Party leader Colin Craig should drop his planned defamation action in the interests of preserving robust political debate.
Mr Craig has begun preparing a defamation case against Greens' co-leader Russel Norman after the MP refused to apologise within a deadline set by Mr Craig on Friday.
The politician and millionaire property manager gave Dr Norman a deadline to retract and apologise for comments he made in a speech at the Big Gay Out two weeks ago.
Dr Norman is standing by his description of Mr Craig as someone who "thinks a woman's place is in the kitchen and a gay man's place is in the closet".
His legal team is also looking at two of Dr Norman's statements in particular - a claim that Mr Craig had "tried to build a society based on intolerance and hatred" and comments made about the Conservative leader's religious beliefs.
