Marie has 15 years’ experience in natural resource management gained from local government, NGO, and private sectors, with a focus on monitoring and policy development. She has authored several national publications focusing on sustainable management and the state of terrestrial ecology. As a reviewer, she brings discipline and objectivity to her clients’ projects. Marie has also been a key adviser to government agencies and private conservation trusts in the policy space, and brings strong analytical and critical evaluation skills to her projects.

Marie and her family live in Upper Hutt, where life is kept busy outside of work with two young daughters and an energetic German shepherd.

Marie joined The Catalyst Group in 2017 after a three-year stint with Environmental Defence Society. She holds degrees in science and environmental law from the University of Auckland, and a PhD from the University of Waikato, which focused on the use of ecological compensation under the RMA. Marie is also a senior associate in the Institute of Governance and Policy Studies at Victoria University and combines research with client-based projects.

  • Resource management policy development, analysis, and review

  • Research programme design, management, and delivery
