Meet The Primary Care Dietitians Team
WellSouth has five New Zealand Registered Dietitians that cover all of Otago and Southland.

Branko Cvjetan
Team Leader - Dietetics, Long Term Conditions and HPV
Dunedin
Originally from Dunedin I returned home in 2023 after 20 years away. I’m privileged to lead both the Dietitian and Long Term Condition teams here at WellSouth. I hold a bachelor’s degree in human nutrition, a postgraduate diploma in Dietetics from the University of Otago and master's in public health from the University of Auckland. I’ve worked in health for over 25 years in hospitals, community and non-governmental organisations.
I’m passionate about mens health, reducing inequity and keeping health advice straightforward and practical. Outside of work I enjoy spending time with family and taking part in local running events—usually somewhere near the back of the field.

Rachel Davidson
Primary Care Dietitian
Central Otago
I’m a dietitian based in the Central Otago/Lakes region. Having been a dietitian for just over 20 years, I’ve worked in a range of places in New Zealand, Australia and the UK, in hospital wards, outpatient clinics, community-based work, primary care and for a charity providing nutrition education to disadvantaged people. I have experience helping people across all ages with a range of medical conditions but have a particular interest in diabetes. I work three days a week for WellSouth and two days for Central Otago Health Services based out of Dunstan Hospital.
I enjoy working alongside people to help them with their health goals and making nutrition less complicated in an increasingly complicated world.
In my spare time I enjoy getting out on the water, waka ama paddling, and spending time with family.

Kirsty Hayr
Primary Care Dietitian
Invercargill
I’m a dietitian based in the Southland region with experience working in London in a paediatric role across community and specialist schools, as well as in a rural hospital here in New Zealand. I have worked with both adults and children, supporting a wide range of nutritional needs.
I take a compassionate, non-judgemental approach and support people to build a positive relationship with food. I understand that food is closely tied to culture, traditions, and connection, and I aim to provide care that respects each person’s lifestyle, preferences, and background.

Natalie Ashton
Primary Care Dietitian
Dunedin
I am a dietitian based in Dunedin covering the Otago area. I have previous experience working as a research dietitian, supporting whānau who are keen for diabetes remission and weight management. My current work at WellSouth has broadened by expertise through working with a range of health conditions which require nutritional support. I am passionate about supporting our communities to improve their health through nutrition. I have a special interest in women's health, specifically around improving fertility outcomes and ensuring nutritional adequacy for pregnant women.

Esme Gray McCoy
Primary Care Dietitian
Dunedin
I’m one of the dietitians based in the Dunedin office, supporting clients across Dunedin and North Otago. I completed my undergraduate degree at the University of Otago and went on to earn a Master of Dietetics from the University of Auckland.
I have experience working with both children and adults, supporting a wide range of medical conditions. I became a dietitian because I’m passionate about helping people and find it incredibly rewarding to support individuals in improving their health through sustainable lifestyle changes.
My approach is grounded in the Health at Every Size (HAES) philosophy, with a strong focus on the quality of the diet rather than weight alone. I aim to provide personalised nutrition advice that fits each individual’s needs, goals, and lifestyle.
