National's housing spokesperson says the Government's doing everything it can to salvage a stale scheme.

Megan Woods is taking over from Phil Twyford as Housing Minister, and will head up a new team of housing Ministers, following Jacinda Ardern's first reshuffle as Prime Minister.

Twyford's been relegated to a role in urban development, Kris Faafoi enters Cabinet with a focus on public housing, while Nanaia Mahuta continues her Maori housing role.

A so-called "reset announcement" on impending changes to Kiwibuild will be announced in the coming weeks.

But Judith Collins told Tim Dower that KiwiBuild's a "mission of failure."

"It's not like Phil Twyford hasn't tried, he's done everything he could do except admit that the policy's completely hopeless and get a new one in," Collins said.

She says they need to ditch the policy altogether, and sort out the Resource Management Act.
