We've got a Minister for Women, so why not a Minister for Men?

That's what ACT Party leader David Seymour wants to know - or better still, he wants all of what he calls "demographic ministers" to be scrapped.

"I think it's wrong to have ministers exist purely for a particular type of person. I actually think that all ministers should be working for all New Zealanders," he says.

It comes off the back of huge criticism of the Minister for Women, Louise Upston, for not directly addressing the Chiefs stripper scandal.

"Men are doing worse than women in just about every imaginable social statistic," Mr Seymour says.

"If you believe it's worth having a minister for a particular type of social issue, then it's far more important in 2016 that it's a Minister for Gender rather than merely women."
