The Prime Minister says the Government is heavily invested in education and knows it needs to step it up.
It's launching a three-month inquiry into school building projects that it says has expectations beyond the scope of delivery.
So far 20 projects have been put on hold, with up to 350 up in the air.
Christopher Luxon says the highly bespoke additions tacked on to projects have blown costs out.
He told Mike Hosking that there may be further delays and re-scoping, but the review is necessary for the long-term.
Luxon says it could legitimately ask how they better manage projects and how to build competence.
