As the climate changes, different groups of people will be particularly vulnerable to its impacts on their health—for instance, outdoor workers, children and older people, and people with existing health needs or who live in poverty. Researchers reviewed 61 papers published in 2024, and found that temperature and extreme precipitation are the main climate risks linked with health in Aotearoa New Zealand. Changes in climate can have both direct and indirect impacts on health, such as heat-related illness, water-borne disease, injury from extreme weather events, or mental ill health. The authors say that climate change is made up of many different, interconnected processes and events that threaten all aspects of health, and will increase the health inequities that already exist.

This paper uses a scoping methodology that seeks to map all the evidence (in this case within academic and grey literature, such as policy documents) on the health impacts of climate change in Aotearoa New Zealand. The review paid particular attention to the climate processes of concern to health and who, where and what activities (e.g., occupations, tasks) are most vulnerable. In addition to consolidating the academic and grey literature, a scoping review methodology also serves to identify gaps and future research priorities. The review—conducted from February to October 2024—included 61 papers from 2,265 initially screened. In conclusion, the review underscores the importance of responses to climate change–induced health addressing the underlying and intersectional risk factors, which the review surfaced.
