WELLINGTON, March 8 - Labour's education spokesman, Chris Hipkins, came to parliament on Wednesday armed with an analysis by Infometrics, commissioned by teacher unions.

He questioned Parata on its findings, saying it showed a 13.9 per cent drop in school capital funding, in real terms, over the past eight years.

Parata told Hipkins it was hard to take him seriously.

"Factually, we have spent a third more in the eight years we have been in government than occurred during the eight years of the previously administration," she said.

"It's all in the government's accounts - for anyone who can read them."

Parata said her associate minister, Nikki Kaye, had commissioned a condition assessment of every school building in the country - which had never been done before.

"That gives us a basis against which to invest taxpayer funds and prioritise redevelopment, refurbishment and earthquake strengthening," she said.
