## About

Stewart Family Holdings traces its roots to 1955 when Bruce Stewart established Calder and Stewart Ltd in New Zealand. Mark Stewart, the current principal, expanded the original construction and manufacturing operations into a diversified investment platform. The portfolio spans real estate, forestry, energy generation, funds management and venture capital. Calder Stewart Land Holdings controls more than 900 hectares of industrial-zoned land, the largest such holding in New Zealand. Stewart Family Forests ranks among the largest privately owned forestry businesses in the country. Stewart Family Capital commits to early-stage companies through direct co-investments and SPVs. Confirmed positions include Precast Ventures and multiple industrial parks such as Awarua Quadrant and Hazeldean Business Park. Activity covers New Zealand and selected opportunities in North America. The firm employs approximately 500 professionals and maintains six offices nationwide. Adjacent vehicles include Calder Stewart Energy for distributed solar assets and FortHill Property for wholesale funds. In 2023 Calder Stewart launched Awarua Quadrant, the largest heavy-industrial zoned area in Australasia. Philanthropic structures comprise the Bruce Stewart Leadership Programme, Hororata Community Trust and Maia Health Foundation. Governance separates operating businesses from the investment holding company through dedicated directors and external trustees. Mark Stewart serves as chair of Christ Church Cathedral Reinstatement Ltd while family members hold board seats at Stewart Family Holdings. This structure allows direct control of land, manufacturing and energy assets alongside third-party venture commitments.
