Judith Collins has apologised to Nicola Willis on behalf of a man who targeted the National MP on Twitter, branding him a "sexist slug".
The exchange took place after Willis, the Opposition's spokesperson for Housing and Urban Development, shared a fiery clip of her blasting Labour's emergency housing plans.
She branded the Government's wellbeing approach as "a hoax", saying child wellbeing is falling by the wayside.
More than 4000 children are living in motels across the country as their parents struggle to find permanent housing.
Minister for Social Development Carmel Sepuloni said in a statement to RNZ there was a major programme of work underway aimed at increasing the supply of public housing and improving affordability and supply.
Willis posted a clip of her impassioned speech on Twitter, exclaiming: "We have a minister who is overseeing the biggest number of children living in motels that we have ever seen in this country!"
A man quickly responded to the post, targeting the MP with a distasteful jab.
"Must be that time of the month huh...," the man replied, before following it up with, "shut your f***ing mouth girl".
Opposition leader Judith Collins swooped in to apologise on behalf of the man, who's Twitter account has since been deleted.
"I'm so sorry Nicola for that sexist slug," Collins tweeted.
But Willis didn't seem phased, even retweeting the man's misogynistic comment, wishing him a nice day.
"Have a nice day Twitter man. In fact, you deserve a whole month of them."
