Cultural monitoring of the environment has emerged in Aotearoa New Zealand as a mechanism to revitalise Indigenous knowledge and support Treaty‐based governance. While cultural monitoring is increasingly salient in environmental policy, there is a need to proceed with awareness about how institutionalisation of cultural monitoring can modify or constrain its intent. Here, we dissect the genealogies and principles of cultural monitoring, identifying how cultural monitoring has been folded into the logic of ‘state of the environment’ reporting. By investigating three examples of cultural monitoring, we analyse how different institutional mechanisms enable and constrain the realisation of cultural monitoring's decolonising intent.
