A new study has exposed significant failures in New Zealand’s approach to tuberculosis, with Māori experiencing rates more than five times higher than New Zealand-born Europeans and researchers warning that gaps in diagnosis, contact tracing and whānau support are allowing the disease to persist.
Public health physician and researcher Dr Nina Scott, of Hei Āhuru Mōwai, says the current system is failing to adequately protect Māori communities and is calling for a dedicated Māori-led strategy to eliminate tuberculosis, commonly known as TB.
The findings, published in the New Zealand Medical Journal on October 9, highlight longstanding inequities in the country’s response to the infectious disease.
Although tuberculosis is often regarded as a disease of the past, approximately 300 people are diagnosed with TB in Aotearoa each year.
Among people born in New Zealand, Māori account for more than half of reported cases, with an annual rate of 3.5 per 100,000 compared with 0.4 per 100,000 for New Zealand Europeans and others.
Researchers say the disparity has persisted for decades, raising serious questions about the effectiveness of existing public health programmes. <Cite refs={[“turn948452search1″,”turn948452search0”]}/>
Waikato Study Exposes Gaps in Contact Tracing
The research examined the records of 17 Māori diagnosed with pulmonary tuberculosis in Waikato between 2018 and 2023.
The review found that 182 contacts had been identified, but only 64 percent were screened for latent tuberculosis infection.
Of those screened, 15 tested positive and were referred for further assessment.
Most identified contacts were household members or hospital staff, with relatively few people outside those settings recorded for screening.
Researchers say this is particularly concerning because Māori whānau networks often extend across multiple households, workplaces and communities.
A narrow approach to contact tracing risks missing people who may have been exposed to the disease.
The study also identified limited documentation of wider wellbeing support, with health navigator assistance recorded for only two patients.
Of the 17 people studied, 16 began treatment and 13 completed it. One person died before formal notification, while two died during treatment.
The findings point to the need for stronger follow-up systems and better coordination between public health services, primary care and Māori community providers. <Cite refs={[“turn948452search4″,”turn948452search1”]}/>
Delayed Diagnosis and Fragmented Services
Dr Scott says the health system’s fragmented approach can contribute to delays in diagnosis and treatment.
Because tuberculosis is relatively uncommon in New Zealand, some general practitioners may have limited experience identifying the disease.
Symptoms can include a persistent cough, fever, night sweats, fatigue and unexplained weight loss.
Early diagnosis is essential because untreated pulmonary TB can spread through the air when an infectious person coughs, speaks or sings.
The disease is treatable with antibiotics, although treatment generally takes at least six months.
Researchers say public health teams also need sufficient staffing and resources to identify contacts, arrange testing and support people throughout treatment.
Without those resources, opportunities to prevent further transmission may be missed. <Cite refs={[“turn948452search1″,”turn948452search5”]}/>
Researchers Call for Māori-Led Elimination Strategy
Dr Scott and her fellow researchers are advocating a different model of care, with Māori communities playing a central role in designing and delivering tuberculosis prevention services.
The proposed approach would strengthen partnerships between public health teams and Māori community providers.
It would also involve community health workers and navigators who understand whānau relationships, can build trust and help people access testing and treatment.
Researchers argue that effective tuberculosis prevention requires more than identifying an infection and prescribing medication.
It also means addressing the circumstances that can make accessing healthcare difficult, including housing conditions, transport, financial pressures and the availability of culturally appropriate services.
A Health Research Council-supported project is already investigating a Māori-led, whānau-centred partnership model aimed at improving contact tracing, treatment and long-term health outcomes.
The objective is to develop an approach capable of eliminating the persistent disparity in tuberculosis rates. <Cite refs={[“turn948452search2″,”turn948452search0”]}/>
A Disease Linked to Generations of Health Inequity
The researchers say the continuing burden of tuberculosis among Māori cannot be separated from historical and structural inequities.
TB has affected Māori communities since the nineteenth century, with early disease-control efforts failing to provide equitable protection.
The study argues that eliminating tuberculosis will require a sustained and targeted response, rather than assuming that general population health programmes will produce equal outcomes for everyone.
For Māori health advocates, the findings reinforce the importance of kaupapa Māori approaches that place whānau, community relationships and cultural safety at the centre of healthcare.
Time for a Different Approach
Tuberculosis can be prevented, detected and treated, but researchers warn that New Zealand’s current approach is not delivering equitable outcomes.
The latest findings raise important questions about whether public health services have sufficient resources, whether contact tracing reflects the realities of Māori communities, and whether whānau are receiving the support they need.
Dr Scott and her colleagues say a dedicated Māori elimination strategy offers a pathway towards changing those outcomes.
The challenge now is whether the health system will translate the research into action — ensuring that Māori whānau have timely access to diagnosis, effective treatment and culturally appropriate support, and that a preventable infectious disease no longer carries such a disproportionate burden for Māori.
