Early life
McTavish was born in Glasgow, Scotland. He is the son of Alec and Ellen McTavish. The family, especially his father, was politically active, and political discourse was common in their household. His family left Glasgow when McTavish was a child, and throughout his adult life, he has lived in places such as Canada, the United States, and England before settling in New Zealand. During school, McTavish and a friend would write and perform comedy sketches, which led to his drama teacher asking him to step in to cover a role in Sheridan's The Rivals after the principal actor became ill. He went on to attend Queen Mary University of London, earning a degree in English literature. This degree course allowed him to perform in three Shakespeare plays per year while at school, and led to McTavish earning his Equity card after performing in a play by Samuel Beckett.
