One of Aotearoa’s leading Māori public health leaders is warning that political ideology must never take precedence over scientific evidence, arguing that public confidence in the health system depends on experts being able to speak freely—even when their advice is uncomfortable for governments.
Speaking with Radio Waatea, Dr Rawiri McKree Jansen discussed a recent editorial published in the New Zealand Medical Journal that argues recent Government decisions risk undermining evidence-based healthcare and the independence of health professionals.
The editorial, co-authored by Dr Jansen alongside public health leaders Dr Belinda Loring, Professor Papaarangi Reid and Associate Professor Rhys Jones, contends that recent ministerial decisions affecting health sector leadership and regulation amount to more than ordinary policy change. The authors argue they represent a broader trend in which scientific evidence is increasingly characterised as “ideology” when it conflicts with political priorities.
The discussion follows controversy surrounding Health Minister Simeon Brown’s decision not to reappoint the Chair and Deputy Chair of the Medical Council of New Zealand after consultation on updated statements relating to cultural safety, cultural competence and Māori health. The decision prompted criticism from senior doctors, who argue political interference in independent professional bodies risks weakening patient safety and clinical standards.
Dr Jansen told Radio Waatea that evidence-based medicine has always evolved through research, peer review and open debate rather than political direction. He said health professionals have both an ethical obligation and a professional responsibility to advocate for patients using the best available evidence, regardless of whether that advice aligns with the Government of the day.
The editorial also raises concerns about a series of wider health policy decisions, including changes to Māori health initiatives, governance arrangements within professional regulatory bodies and proposals that would give ministers greater influence over health practitioner organisations. According to the authors, these developments collectively risk reducing the independence of institutions responsible for protecting public safety.
For Māori, Dr Jansen said the debate has particular significance.
He noted that decades of research consistently demonstrate Māori experience poorer health outcomes across a range of conditions, including cardiovascular disease, cancer, diabetes and life expectancy. Addressing those inequities, he said, requires evidence-informed approaches that acknowledge the different barriers Māori face when accessing healthcare rather than assuming identical treatment always produces equitable outcomes.
The editorial argues that research supporting targeted interventions to reduce inequities is well established both internationally and within New Zealand. It warns that dismissing such evidence as ideological risks reversing decades of progress towards improving health outcomes for Māori and other populations experiencing disadvantage.
The concerns expressed by Dr Jansen have been echoed by other senior clinicians. Doctors quoted by national media have accused the Government of creating an environment in which scientists and medical experts may feel reluctant to publicly challenge policy decisions for fear of political repercussions, arguing that robust public debate is essential to maintaining a safe and effective health system.
The Government has rejected suggestions that it is suppressing scientific opinion, maintaining that ministers have a mandate to set health policy while ensuring regulatory bodies remain focused on delivering effective services for all New Zealanders.
For Dr Jansen, however, the issue extends beyond politics.
He says healthcare must remain grounded in robust evidence, transparent scientific inquiry and the ability of clinicians to raise concerns without fear or favour. In his view, protecting those principles is essential not only for Māori health but for maintaining public trust in the entire health system.
As debate over health reform continues, questions about the relationship between science, politics and public policy are likely to remain at the forefront of discussions about the future of healthcare in Aotearoa.
