Supporting whānau during COVID-19 pandemic in Aotearoa New Zealand: a systems thinking case study

Background: The Aotearoa New Zealand COVID-19 pandemic response has been hailed as a success story, however, there are concerns about how equitable it has been. This study explored the experience of a collective of Māori health and social service providers in the greater Wellington region of Aotearoa New Zeland delivering COVID-19 responses.

Methods: The study was a collaboration between a large urban Māori health and social service provider, Tākiri Mai Te Ata whānau ora collective, and public health researchers in Aotearoa New Zealand. Two online workshops were held with staff of the Māori service provider, collectively developing a qualitative causal loop diagram and generating systemic insights. The causal loop diagram showed interactions of various factors affecting COVID-19 response for supporting whānau (Māori family/households) at a community level. The iceberg model of systems thinking offered insights for action in understanding causal loop diagrams, emphasizing impactful changes at less visible levels.

Results: Six interacting subsystems were identified within the causal loop diagram that highlighted the systemic barriers and opportunities for effective COVID-19 response to Māori whānau. The medical model of health service produces difficulties for delivering kaupapa Māori services. Along with pre-existing vulnerability and health system gaps, these difficulties increased the risk of negative impacts on Māori whānau as COVID-19 cases increased. The study highlighted a critical need to create equal power in health perspectives, reducing dominance of the individual-focused medical model for better support of whānau during future pandemics.

Conclusions: The study provided insights on systemic traps, their interactions and delays contributing to a relatively less effective COVID-19 response for Māori whānau and offered insights for improvement. In the light of recent changes in the Aotearoa New Zealand health system, the findings emphasize the urgent need for structural reform to address power imbalances and establish kaupapa Māori approach and equity as a norm in service planning and delivery.
