This document is the Interim Report (Report) of the SFF. It represents the collective, and voluntary, efforts of the Sustainable Finance Forum (SFF) undertaken from January 2019 to October 2019. The report sets out why we need to shift, urgently, to a sustainable economy. It proposes the principles and characteristics of a sustainable economy and financial system - drawing upon a Māori world view of Kaitiakitanga. The forum has reviewed much of the latest local and international thinking and best practice, along with a ‘future state’ vision for New Zealand’s financial system. It assesses how well our current financial system performs against that benchmark and poses some initial ideas and questions on Potential Pathways for change.
