Cabinet Minister Judith Collins has accused Labour leader David Cunliffe of sexism after he referred to her as a "trout" in an opinion piece.
Mr Cunliffe made the comment in a blog post on the website The Ruminator this afternoon.
He wrote: "The original brief was to respond to a post by Judith Collins. My post was going to be about snapper, not trout. But considering that issue, along with Judith's leadership aspirations, has floundered, I'll try another hook."
Asked to respond on Twitter, Mrs Collins said: "Imagine the outcry from Labour if one of Nat male MPs called a Labour woman a trout."
