Former Saint Kentigern College maths teacher, Dr Edward Coad, has been censured due to his participation in an Instagram group chat with former students, which discussed sex and drugs, Stuff reports. In August 2019, Coad discussed genital sizes, prostitution, binge-drinking and drugs in the chat with his former year 12 students. The discussion took place after he had left the private high school to take up the position of head of maths at Northern Southland College in Lumsden. He resigned in December 2019 during a Teaching Council investigation into his conduct.
