Stewart and Tricia Macpherson formed Stetson Productions Ltd in October 1973.
 Since then they have developed a number of companies under the overall umbrella of The Stetson Group not only in New Zealand, but also in Australia, the UK and the US. Both Stewart and Tricia have a single goal – to always have the best show on the stage at every performance – which entails looking after a tour in great detail. Their satisfaction comes from stimulated and appreciative audiences. Over almost four decades many people have worked with Stetson, and gone on to either become Producers, or stayed in the profession in a chosen specialised area.
