Climate change mitigation and adaptation provide important opportunities for impact assessment (IA) practice. In late November 2019, the New Zealand Association for Impact Assessment (NZAIA), in partnership with the Secretariat for the Pacific Regional Environment Programme (SPREP), held a conference in Auckland under the title Climate Change Mitigation and Adaptation: assessing the impacts. The topic recognised the importance of climate change in the political arena in recent years in New Zealand and the wider Pacific region and the opportunity to apply IA to policy and planning. The conference had a significant Pacific island countries and territories (PICTs) component, which is the basis for this issue of NZAIA’s Impact Connector, produced with the support of SPREP for the Pacific impact assessment and climate change communities. A separate issue of Impact Connector presents a number of articles based on verbal and poster presentations mainly from a New Zealand perspective.
