Policy challenges of managing naturally occurring respirable mineral dust in Aotearoa New Zealand

Abstract

Researchers and environmental planners have raised concerns about human exposure to naturally occurring respirable mineral dust (RMD), including erionite and naturally occurring asbestos. However, it is unclear how existing policy frameworks address and manage the risks of exposure to RMD, and little has been offered regarding how satisfactory policy frameworks could be developed. We draw on international research, policy documents and key informant interviews to examine how these risks are presently addressed globally and in the context of the Aotearoa New Zealand policy landscape, identifying key domestic challenges confronting effective risk governance. We recommend a collaborative effort from various disciplines to understand these new risks. We further recommend the development of an independent mechanism to evaluate risks from long-term or latent hazards such as these.
