The education union is accusing Education Minister Hekia Parata of 'fake news.'

NZEI national secretary Paul Goulter said the Minister has made claims in a number of media interviews, that school funding has increased by 35 percent under National.

He said these claims are 'Trump-style politics' - in that they are simply not true.

Mr Goulter said they have taken the Ministry's own funding information, engaged Infometrics to do some research, and found that increase is actually less than four percent.

"There is a significant discrepancy between the number that the Government have been putting out there for quite some period of time now, and the number that the Education Counts website actually discloses," he said.

Labour's education spokesman Chris Hipkins backed the Infometrics study, and echoed NZEI's view of the Education Minister and her claims about school funding.

"The numbers that Hekia Parata uses are certainly misleading, if not alternative facts," he said.

However, Ms Parata said a quick google will prove otherwise.

"There aren't an alternative set of facts. A whole lot of professional public servants are involved in the Budget process.

"The idea that there's one set of facts for the unions and one set of facts for Ministers just doesn't bare scrutiny."
