Conservatives' leader Colin 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 this afternoon.
Mr Craig is also considering new legal action against Dr Norman for comments made on TVNZ Breakfast this week.
The politician and millionaire property manager had given Dr Norman a deadline of 5pm today to retract and apologise for comments he made in a speech at the Big Gay Out two weeks ago.
Dr Norman was 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''.
Mr Craig said this afternoon he had asked his lawyers at Chapman Tripp to draft a statement of claim and advise him on the likely costs and timeframe for a defamation case.
