John Mason commenced his career in the trucking industry with an apprenticeship at the International Harvester branch in Christchurch in 1984. International Harvester Christchurch became Southern International Ltd, and John continued his service there as a heavy diesel mechanic working on International trucks and for a time, on Dressta and International construction equipment and farm machinery. Changes in the industry meant Iveco became the dominant brand for Southern International Ltd, and for a time John was the technical expert for Iveco New Zealand. When Southern International Ltd was purchased by the Stevenson Group in 2007, John assumed the role of Service Manager. In the ensuing years, satellite workshops were established at two sites in the Christchurch region, and one in Greymouth. The business was acquired by AB Equipment Ltd in 2014, and John continued in his role as Service Manager in the growing business. Work through the Pacific Fuel Haul workshop had brought about a business relationship with Ross Graham, so when the opportunity to form a partnership with Ross Graham and Sheldon Close in the purchase of Intertruck South arose, John saw the potential and jumped at the chance. Within the next year, they acquired the workshop business of New Zealand Trucks which continues to grow and provide service to a New Zealand-wide customer base. John is first and foremost a family man, and outside work when time allows, John follows rugby, enjoys fishing exploits, and he and Sonya socialise with their wide network of friends.
