Māori Health & Health Equity in Aotearoa

Introduction: Māori Health in Aotearoa New Zealand

Māori are the tangata whenua — the indigenous people — of Aotearoa New Zealand. Despite being a founding partner of Te Tiriti o Waitangi (1840), Māori have experienced systematic health disadvantage since colonisation. Understanding Māori health requires moving beyond individual risk factors to examine the historical, structural, and cultural determinants that have shaped — and continue to shape — Māori health outcomes.

Key Māori Health Statistics (Aotearoa NZ)

The health gap between Māori and non-Māori is stark and persistent across virtually every health domain:

Life expectancy: Māori men live approximately 7 years less than NZ European men; Māori women approximately 7 years less than NZ European women (2017–2019 period life tables). This gap has narrowed since the 1990s but remains substantial.

Mortality: Māori have higher age-standardised mortality rates for cardiovascular disease (~2×), cancer (~1.5× incidence, significantly worse survival), diabetes (~3× prevalence), and respiratory disease. Māori mortality rates occur at younger ages — premature mortality (under 75 years) is substantially higher.

Infant mortality: Māori infant mortality is approximately 1.5–2 times that of NZ European infants. Sudden unexpected death in infancy (SUDI) rates are 4–6 times higher in Māori infants, strongly associated with bed-sharing, smoking, and socioeconomic factors.

Mental health: Māori have higher rates of psychological distress, suicide (particularly youth suicide), and methamphetamine-related harm. Te Rau Hinengaro (2006, NZ Mental Health Survey) showed Māori had higher 12-month prevalence of any mental disorder.

Rheumatic fever: as previously noted, Māori children have ~40× the rate of NZ European children — a preventable condition driven entirely by structural inequity.

Disability: Māori have higher rates of disability and chronic health conditions limiting daily activity.

Te Whare Tapa Whā

Te Whare Tapa Whā ("the four-sided house") is a holistic model of Māori health developed by Tā Mason Durie in 1984 and published in his landmark work *Whaiora: Māori Health Development* (1994). It uses the metaphor of a wharenui (meeting house) with four walls — all four must be strong for the structure to stand.

The four dimensions (taha) of health:

1. Taha Tinana (physical health): the physical body, its functioning, growth, and capacity. Includes nutrition, exercise, sleep, freedom from disease and pain. Most closely aligns with biomedical models of health.

2. Taha Hinengaro (mental and emotional health): thoughts, feelings, and emotions; the capacity to communicate, think, and feel. Encompasses psychological wellbeing, cognitive function, and emotional resilience. Māori understand the mind and body as inseparable.

3. Taha Wairua (spiritual health): the spiritual dimension; connection to whakapapa (genealogy), to atua (ancestors and supernatural forces), to the natural world (te ao mārama), and to te kore (the unknown). For Māori, spiritual health is not metaphorical — it is a fundamental dimension of wellbeing. Disconnection from wairua is understood to cause illness.

4. Taha Whānau (family health): the extended family and social context. Whānau (family) is the fundamental social unit for Māori — it provides identity, support, belonging, and a sense of continuity with past and future generations. Health is a collective, not merely individual, concern.

A fifth dimension is sometimes added: Whenua (land and roots) — connection to one's ancestral land (turangawaewae — a place to stand). Disconnection from land through colonisation and urbanisation is understood as a significant determinant of Māori health.

Clinical application: Te Whare Tapa Whā challenges clinicians to assess all four dimensions. A biomedical approach addressing only taha tinana while ignoring wairua, hinengaro, and whānau is incomplete. Kaupapa Māori health services are explicitly designed around this holistic framework.

Historical Determinants of Māori Health

Māori health today cannot be understood without understanding the history of colonisation:

Pre-contact: Māori were generally healthy; the population is estimated at 100,000–200,000 at the time of European contact. Disease burden was primarily parasitic, nutritional, and trauma-related; epidemic infectious diseases were absent.

Post-contact disease introduction (1790s–1840s): introduced epidemic diseases (influenza, measles, whooping cough, typhoid, gonorrhoea) devastated Māori communities with no prior immunity. The Māori population declined from approximately 100,000–120,000 in 1840 to a nadir of approximately 42,000 by 1900 — a decline of over 60%. This catastrophic demographic collapse created multigenerational trauma.

Land alienation: the New Zealand Wars (1860s–1870s) and subsequent Native Land Court processes (from 1865) resulted in massive alienation of Māori land. Between 1840 and 2000, Māori lost approximately 96% of their land base. Land is central to Māori identity, food production, and economic wellbeing — its loss created poverty that persists across generations.

Urbanisation (1950s–1970s): the post-WWII rural-urban migration moved the majority of Māori from ancestral rohe (territories) to cities, breaking connections to land, whānau networks, and tikanga (customs). Urban Māori communities formed but often in low-income areas with poor housing, limited employment, and social dislocation.

Tohunga Suppression Act 1907: criminalised traditional Māori healing practices (tohunga were expert practitioners of tikanga, healing, and spiritual practice), suppressing kaupapa Māori approaches to health for decades.

Systemic racism: institutional racism within the health system — implicit bias in clinical encounters, under-representation of Māori health providers, services designed without Māori input, and inadequate resourcing of Māori health — has been documented by the Waitangi Tribunal (WAI 2575) and multiple research studies.

Treaty of Waitangi Principles in Health

The New Zealand Public Health and Disability Act 2000 and Pae Ora (Healthy Futures) Act 2022 both require health entities to give effect to Te Tiriti o Waitangi. The Ministry of Health uses a four-principles framework:

Partnership: Māori must be partners in all aspects of health sector governance, planning, and delivery. This means genuine co-design, not just consultation.

Participation: Māori must participate in health sector decision-making at all levels — governance, management, clinical teams, policy development.

Protection: the Crown must actively protect Māori health and wellbeing, ensure equitable access to services, and work to eliminate health disparities.

Equity (sometimes added as a fourth or fifth principle): health outcomes for Māori should be equal to other New Zealanders — the Crown must take active steps to close the gap.

Kaupapa Māori Health Services

Kaupapa Māori ("according to Māori ways") health services are services designed, owned, and delivered by Māori for Māori, grounded in te reo Māori (Māori language), tikanga Māori (Māori customs and values), and the holistic frameworks of health such as Te Whare Tapa Whā.

Examples: Māori-led primary health organisations (PHOs), hauora Māori providers, Te Kohanga Reo (Māori language nests for children), marae-based health services, Māori mental health services.

Evidence shows kaupapa Māori services achieve better health outcomes for Māori than mainstream services — higher uptake, better adherence, and more appropriate care — because they are culturally safe, conducted in te reo Māori where appropriate, and aligned with Māori worldviews.

Cultural Safety

Cultural safety (kawa whakaruruhau) was developed by Māori nurse educator Irihapeti Ramsden in the 1980s. It goes beyond cultural awareness (knowing facts about cultures) or cultural sensitivity (being respectful) to require:

• Reflection on one's own cultural position and power
• Recognition that the health professional's culture affects clinical interactions
• Commitment to not diminishing, disempowering, or disrespecting the cultural identity of the patient
• The patient (not the provider) defines whether care is culturally safe

Cultural safety is now a professional requirement for all regulated health professionals in NZ (Medical Council of NZ, Nursing Council of NZ). It is explicitly linked to reducing health disparities — unsafe clinical encounters deter Māori from seeking care.
