Executive Board Members: 

Dr Richard Jaine, Secretary
Richard is a Public Health Medicine Specialist who works at the University of Otago, Wellington. His interests include tobacco control, healthy food environments, and the health impacts of climate change. He is also a long-suffering Hurricanes rugby fan.


Dr Mark Smith, Treasurer
Mark 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
Alison is a Public Health Medicine Specialist based in Auckland and with special interests in child health, global health, health promotion, and human rights. 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 Public Health Medicine Specialist in Wellington. He is Chief Advisor Population Medicine and Deputy Medical Director for a government health funding agency, with clinical leadership in epidemiology, clinical epidemiology and technology assessments/health economics. He was a foundation Co-convenor of OraTaiao 2010 to 2013, chairs the Policy Committee of the NZ College of Public Health Medicine, and is on the NZCPHM's Council and the Board of the NZ Medical Association. He has particular interest in international climate justice/equity 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 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 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 George Laking
George (Te Whakatōhea) is a Medical Oncologist in Auckland and Northland. George's involvement in tobacco control spurred an interest in the motivated denial of science. He sees a parallel between people’s adjustment to major illness, and society’s adjustment to looming environmental catastrophe. Outside of his clinical and advocacy work, he likes to get away on bikepacking trips.  


Dr Andrea Forde
Andrea is a founding member of OraTaiao. She has worked with the Ministry of Health in NZ, the Commonwealth’s Department of Health and Ageing in Australia, and the World Health Organisation in both the Lao People’s Democratic Republic and in Beijing, China. Most recently she worked on vaccines in the pharmaceutical industry. She has also taught on communicable diseases and policy responses, public health law, and ethics, including at the Australian National University. She is a keen walker and gardener – and opera buff. It has been a natural segue back onto the Board with another headfirst plunge into the impacts of climate change on health.


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.
