Labour leader David Cunliffe's apology for being a man is "insulting" because not all men are abusive, Prime Minister John Key says.
"It's a pretty silly comment from David Cunliffe," Key said.
"The problem isn't being a man, the problem is if you're an abusive man, and I think it's a bit insulting to imply that all men are abusive.
"A small group are and they need to change their behaviour and be held to account.
"Is he really sincere about that statement? Tomorrow afternoon is he going to go down to the local rugby club and say 'I'm sorry for being a man'? I don't think so."
Cunliffe made the apology at a Women's Refuge symposium today, where he also pledged to invest an extra $60 million into family violence services.
He spoke of the "bullshit, deep-seated sexism" still prevalent in New Zealand.
