A teacher claims he was forced out of Auckland's Tamaki College for being an atheist.
Christopher Scott Roy was employed by the college from February 2007 until he resigned in September 2010.
Mr Roy has taken a case to the Employment Relations Authority claiming he was constructively and unjustifiably dismissed because of his atheist beliefs.
In a decision published by the authority this week, Mr Roy said Tamaki College "saw Christian/Mormon faith as a core responsibility to which he was indifferent and reluctant to accept or practise as a condition of his employment".
The Tamaki College Board of Trustees disagrees, and said Mr Roy signed a record of settlement with the college on November 5.
