Professional Registration

for Qualified Clinical Nutritionists

The Clinical Nutrition Association (CNA) is based in Aotearoa New Zealand and offers professional registration to qualified Clinical Nutritionists, and student membership to those currently enrolled in an approved nutrition course. We also act as a point of contact and referral for other health professionals, media and the public.

A Registered Clinical Nutritionist (RCN) holds a nutrition qualification that includes clinical training which has been accredited by the CNA. They work in private practice and/or in a corporate setting providing evidence-based holistic nutrition, personalised health assessment and lifestyle interventions to support health, wellbeing and performance.

Undergoing clinical training is the key difference between a Registered Clinical Nutritionist and a Nutritionist. This clinical training includes health history assessment, consultation skills, clinical examination, nutritional assessment, appropriate functional and diagnostic testing, developing health plans and a minimum of 300 hours of clinical practice.

Here you can find a Registered Clinical Nutritionist and learn more about what to expect when you book a nutrition consultation with one of our members.
