Bevan Walsh is the founder of Third Age Health Services. In 2007, he founded a mobile medical service business with just $160 invested, with the intention of providing GP consultations after-hours to clients in their homes. He recognised the untapped potential in the aged residential care sector and pivoted the business accordingly. Third Age Health was formally established around 2010 and has since become a leading provider of primary healthcare solutions for the elderly in New Zealand, providing specialised 24/7/365 healthcare services to aged residential care (ARC) facilities. Bevan served as Chairman of the Board from the company's NZX listing in February 2021 until a board restructure in October 2025, when he transitioned to Non-Executive Director to focus on governance. He remains a significant shareholder, holding approximately 43% of the company.
