The Te Tai Tokerau Principals Association is threatening to create a public blacklist of schools where it deems the boards are "out of control".
However, the association has been blasted by the advisers of boards for circulating "snide and unproven allegations".
New Zealand School Trustees Association (NZSTA) president Lorraine Kerr said creating a blacklist would do nothing positive for education in Northland.
Te Tai Tokerau Principals Association president Pat Newman said there had been concerns for a number of years about school boards that had acted in an "unacceptable" manner towards a number of principals.
"A simple list published on, for instance, our website, would certainly inform people to be wary about applying," he said.
