Current Executive Board Members: 

Dr Rhys Jones    

Rhys (Ngāti Kahungunu) is a Public Health Medicine Specialist and father of three boys who lives in Auckland. He is a Senior Lecturer in Māori Health at the University of Auckland. His research interests include ethnic health inequities, the role of health professional education in advancing indigenous health, and environmental influences on Māori health.


Dr Alexandra Macmillan

She lives in Dunedin, where she is involved in research to improve policies for health, equity and environmental sustainability across transport, housing and food systems.

Dr Mark Smith

Mark Smith is a Consultant General Surgeon at Dunedin Hospital with a special interest in surgery for benign and malignant foregut conditions including bariatric surgery for obesity. His interest in climate change developed when he was living in Portland, Oregon, and could see first hand how some of the drivers of climate change also affected human health. He returned to NZ in 2011 and has lived in Dunedin with his family since 2018. Mark currently fills the role of Treasurer for OraTaiao and is learning to keep quiet in the future when exec roles are allocated.


Dr Alison Blaiklock

She is a former Executive Director of the Health Promotion Forum of New Zealand and was founding chairperson of Action for Children and Youth Aotearoa. She has been recognised by the Public Health Association of New Zealand as a Public Health Champion.


Dr Russell Tregonning

Russell is a semi-retired orthopaedic surgeon. He belongs to a number of groups in Wellington concerned with active and climate-friendly public transport. He is a founding member of Congestion-free Wellington, representing OraTaiao on that coalition of 9 local organisations. He reads climate change science at bedtime but still sleeps well.


Dr Scott Metcalfe

Scott is a Wellington-based Public Health Medicine Specialist, parent of three grown-ups and proud grandpa/Lolo. He is Chief Advisor Population Medicine and Deputy Medical Director for a government health funding agency (epidemiology, clinical epidemiology and technology assessments/health economics). He was a founding Co-convenor of OraTaiao 2009-2012, chairs the Policy Committee of the NZ College of Public Health Medicine, and is on the Board of the NZ Medical Association. Interests include international climate justice and quantifying nations' fair shares.


Dr Rebecca Randerson

Rebecca is a General Practitioner from Wellington. Rebecca’s particular interest is the carbon costs and environmental impacts of healthcare. There is an irony in caring for patients’ health in a way that is damaging to the health of the planet we rely on. Good opportunities exist to reduce carbon emissions in hospitals with secondary benefits of cost savings and improved morale.


Liz Springford

Liz Springford is a Wellington-based climate policy analyst, parent of three grown-ups, and proud grandma/Lola. Liz enjoys writing media releases, submissions (mostly), policy (Masters of Public Policy, BA – Economics & English Lit), her e-bike and the Island Bay cycleway.  She’s impatient for a fairer healthy Aotearoa Net Zero, calculating how fast NZ can move to help keep global warming confidently within 1.5 degrees.


Dr Matt Jenks

Matt Jenks is an anaesthetist at Dunedin Hospital. He has long had an interest in environmentally sustainable healthcare practice initially focussing on operating theatre recycling and more recently the contribution of healthcare to the problem of climate change. He is an executive member of OraTaiao the New Zealand Climate and Health Council and runs his Hilux Surf on waste vegetable oil from the local Japanese restaurant.


Dr Carmen Chan

Carmen is a house surgeon working in the Wellington region. She cares deeply about issues in global health, and the impacts of climate change upon livelihoods, and the environment. Carmen strives to connect those of her generation with playing a role in creating 'health climates, 'healthy people'. An ardent tramper, you'll find her out scaling a mountain in her spare time.


Bruce Tsai

Bruce is a 4th year medical student passionate about health advocacy and sustainability. He has presented a statement to the WHO and facilitated a breakout at the UN Conference on Housing and Sustainable Urban Development. He is currently the Pacific Regional Focal point for the UN MGCY Co-ordination team for oceans and marine resource conservation (SDG 14). In his spare time he enjoys making music, playing basketball, or a game of chess.
