A Whanganui teacher has been censured for serious misconduct.
Karl-John Allen was a teacher at Whanganui High School in October 2014 when he sent a letter which described the school principal as "someone who discriminates" and implied the principal was "bigoted and racist", according to the teachers' Disciplinary Tribunal.
The tribunal's findings have been released in a report which says Mr Allen's letter went out to 28 people, including senior school leaders, the PPTA union, Maori staff and local iwi.
The letter followed a disagreement between Mr Allen and principal Garry Olver in the school staffroom in September which had not been resolved.
Mr Allen had taken sick leave due to stress and informed the principal that he would be addressing his concerns in writing and that he felt "culturally unsafe" in meeting the principal.
