In the wake of a poll with disastrous results for his leadership, Simon Bridges hit back with a fiery first Parliamentary speech of the year.
He chastised the Government for forming working groups, of which he said there are "more than 200".
"In its ambition to me measured on its vague intentions, it is proving to be completely incapable of delivering good outcomes for New Zealanders," he said.
He accused the Prime Minister of "vague virtuous talk", and mocked her proclamation that 2019 will be the "year of delivery".
KiwiBuild was another target, with Mr Bridges claiming the Government is embarrassed of its flagship housing policy, noting Jacinda Ardern didn't talk about it in her speech.
"Like so much of this Government, it was intentions, it was talk of kindness and wellbeing, and not a lot else."
It was a passionate speech, with Mr Bridges singling out Ministers including Andrew Little, Carmel Sepuloni and Grant Robertson. He didn't take kindly to being heckled by the other side of the House, either.
"I've got about 10 minutes of material to fit into six minutes, be quiet!" he admonished at one point.
