Who We Are
Founding Trustees

Ian and Wendy Kuperus live in Auckland, have four adult children and one grandchild. A born and bred South Islander, Ian has been passionate about creating a better tax environment for New Zealand businesses for his whole career. Prior to starting Tax Management New Zealand, the world’s first tax intermediary, Ian worked in a number of senior tax roles in Wellington and Auckland. Wendy grew up on a farm north of Auckland, working as a nurse in both Hamilton and Wellington. Wendy is currently involved in a number of community organisations supporting families, children and young people.
Ian is the founding director of TMNZ and is also an active investor in several engineering and technology start-up ventures. He is passionate about giving back to the community and has been a long-time supporter of many charities working with disadvantaged people in New Zealand and around the world.
Both Ian and Wendy are committed Christians — a life and faith journey that has guided and challenged their decision making in family, business and the community.
