The online Te Aka Maori Dictionary is being accused of publishing 'political spin' in its new definition of charter schools, or Kura Hourua.
The Auckland University of Technology-run tool defines Kura Hourua as partnership schools and goes on to explain how they will bring different sectors together to provide new opportunities for students to achieve educational success.
Green Party co-leader Metiria Turei says the definition is absolutely political and should not be included. She says it wrongly buys in to Government spin about hotly debated schools that don't yet exist.
Labour's Nanaia Mahuta agrees it's a Government constructed definition.
The Maori Party wouldn't comment.
Meanwhile, a Maori Development professor at AUT in charge of updating the site says he is open to making changes.
John Moorfield says the definition of Kura Hourua was taken from the Ministry of Education website because he had no other source.
Mr Moorfield says if people don't agree with the definition and give him a reason why, then he's happy to modify it.
