The New Zealand Public Health and Disability Act (NZPHD, 2000) enabled the creation of 20 District health boards (DHBs). Established in 2001, DHBs have overseen and been responsible for providing, or funding provision of most health services throughout New Zealand (Dwyer et al, 2014). Public Health Organisations (PHOs) were introduced to improve access to services and coordination of providers (Barnett & Barnett, 2004). In 2018, the government commissioned an independent review into New Zealand’s health system that was conducted over an 18-month period. The review noted a fragmented health system that struggles to deliver equity and consistency for all New Zealanders (Health New Zealand - Taranaki, n.d).
On 1 July 2022, all 20 DHBs were disestablished to become part of Te Whatu Ora (Health New Zealand). Te Whatu Ora is expected to work in partnership with Te Aka Whai Ora (Māori Health Authority) and Manatū Hauora (Ministry of Health). Te Aka Whai Ora is a newly established entity responsible for ensuring the health system works well for Māori. Iwi-Māori partnership Boards will have decision-making roles at a local level, and jointly determine local priorities and delivery with Te Whatu Ora. Iwi-Māori Partnership Boards will also be the primary whānau voice within the new public health system (Future of Health, n.d.). The latest health reform, with the creation of the partnership arrangement, heralds the promise of a new public health system that will better address the persistent health inequities Māori experience.
Existing health disparities (Ministry of Health, 2019), political marginalisation, discriminatory systems and racist practices (Lewis, Williams & Jones, 2020) that maintain inequitable health access compound risks of the known biophysical impacts of climate change (Holder, 2020; O’Niell, Green & Liu, 2012). As climate change continues, adverse health impacts are expected to be more severe and borne disproportionately by indigenous people and groups already suffering health inequities (Jones et al. 2014; Royal Society of New Zealand/Te Apārangi 2017). While there is a limited pool of public health-related climate change research in New Zealand, there is emerging evidence about the threat of changing climatic conditions on Māori well-being and health, as well as examples of Māori-led initiatives to address these risks (Jones et al. 2014).
A range of factors, with roots in historic and ongoing forms of marginalisation, manifest as disproportionate risks to Māori health in the context of climate change. These factors include existing Māori health disparities (Ministry of Health 2019); poorer access to and quality of health care (Graham & Masters‐Awatere 2020); socio-economic deprivation (Jones et al. 2014; Jones 2019); and political marginalisation (Lewis et al. 2020).
Māori views of health are holistic and recognise the relational and kin-centric connection between people, the land and ecosystems (Harmsworth & Awatere 2013; Panelli & Tipa 2007). However, Eurocentric views, based on universalistic approaches, have been prioritised in public health and climate change policy while the values fundamental to Māori views of health remain underappreciated and marginalised (Harmsworth & Awatere, 2013; Harris & Tipene, 2006; Lewis et al. 2020).
On a global scale, climate change is the biggest threat to humanity through compounding ecological disasters such as extreme weather events, rising sea levels, ocean acidification, increases in non-communicable diseases, along with the spread of vector-borne diseases (Bolton et al., 2019; IPCC, 2019, 2021; Jones et al., 2014, Royal Society of New Zealand/Te Apārangi, 2017). When it comes to examining climate change impacts, a focus on global averages has tended to mask disparities. Indigenous people are disproportionately impacted by climate change (Abate & Kronk, 2013; Nursery-Bray et al, 2020). As a consequence, the need to give greater consideration of indigenous people in climate change conversations is essential (Begay & Gursoz, 2018). Jones et al. (2020) had recently observed that few studies have examined climate change health impacts on Indigenous or Māori people, despite the clear need for these assessments. Other socially and politically marginalised groups within society (such as young, disabled, unwell and the impoverished) tend to be overlooked in climate change assessments. The presence of large numbers of Māori within these marginalised groups highlights the levels of intersection with climate change risk.
Those most at risk of exposure to floods, droughts, extreme heat, and the spread of vector-borne diseases, Māori, Pacific, and low-income groups in New Zealand, are also vulnerable to adverse health impacts from climate change (New Zealand College of Public Health Medicine, 2013; Howden-Chapman et al., 2010). Vulnerability to risk from climate change impacts food security, infrastructure and housing means that important determinants of health (such as healthy nutrition, safe drinking water and healthy homes) are undermined (Bennett et al., 2014).
The Sendai Framework for Disaster Risk Reduction (United Nations, 2015) identifies that public and private investment in disaster risk prevention and reduction is required through structural and non-structural measures in order to enhance the multifaceted nature of community and environment resilience. Pae Ora – Healthy Futures, the overarching aim for He Korowai Oranga, the national strategy for Māori health, calls for the impact of climate change on health to be addressed as part of Wai Ora – healthy environments (Ministry of Health, 2014).
The complex vulnerabilities experienced by Māori intersect to create a multifaceted and enduring health crisis that will be exacerbated by climate change. The vulnerability of Māori is not experienced simplistically, thus policy planning and response should also not be simplistic, insular or linear. To improve the health system, radical, meaningful and multiscalar change is required (Masters-Awatere, 2017). This is especially so with regard to institutional responses to climate adaptation. Multilevel consideration via national health strategies, annual plans, health practitioner competencies and Iwi-Māori representation will need to be responsive to climate adaptation with respect to vulnerable urban Māori populations.
Between 2018 and 2038, the Māori population is predicted to increase significantly in the urban centres of Auckland, Waikato and Canterbury. Vulnerable urban Māori are identified as being at risk in terms of unemployment (Stubbs et al., 2017), living in overcrowded housing or experiencing homelessness (Groot et al., 2011), the added constraint of climate change on those with fewer resources requires urgent attention. Hallegate and Rozenberg (2017) highlight that the vulnerable population of urban Māori have fewer resources, such as whenua and access to clean waterways, to fall back on and therefore have a lower adaptive capacity in the face of climate change.
This paper presents a sample of the work undertaken as part of a two-year research project that worked with three DHBs in the midland region (Te Manawa Taki) of New Zealand’s North Island. These DHBs contained a large proportion of Māori that captured both urban and rural Māori groups. Guided by the researchers, a climate change policy framework that considered whānau-centred healthcare knowledge, needs, resources and aspirations, to contribute to a transformed and responsive health system was designed.
The aim of this project was to facilitate consideration of the social impacts of climate change in the context of health. By assisting these health institutions (DHBs) to better prepare to deal with the scale and pace of climate change, the flow on impacts for other contracted service providers (whether iwi, mainstream or government agencies) will be highly beneficial. Through a collaborative partnership, we co-designed a policy framework (“Haumanu Hauora”) to guide policy formation to mitigate risk to Māori (and others) in the context of climate change.
