This recommendation paper is published in the context of Aotearoa New Zealand recently entering public consultation for regulating modern slavery in supply chains. It provides direction for a legislative design that is compliant with international developments and, at the same time, considers Aotearoa New Zealand’s geopolitical and cultural context. It is not a response to the Government’s consultation proposal, but rather an independent resource, setting out recommendations based on research and the authors’ modern slavery law and practice expertise.
