Glenys HanleyOwaka residents say The Catlins Area School should be more transparent with parents over revelations the principal’s husband is a convicted sex offender. During the assault, he attempted to rape a tourist in a toilet cubicle while armed with a knife. "What else could they be sweeping under the rug from parents of the school?" A parent of a former pupil at the school called on the board to address the issue and answer questions. Board of trustees presiding member Simon Walker could not be reached for comment yesterday.
