The Secretary for Education Iona Holsted has told MPs the single biggest investment ever made in schools has failed to deliver and politicians' policy flip-flops are partly to blame for schools' achievement problems.
Holsted was speaking to Parliament's Education and Workforce Select Committee which is holding its annual review of the Education Ministry's performance.
The review is continuing this morning with the committee expecting to hear from the Education Minister Erica Stanford and Associate Education Minister David Seymour.
Education Correspondent John Gerritsen spoke to Ingrid Hipkiss.
