Stop managing symptoms. Start finding answers. IFM-trained practitioner Tonia Peachey investigates the root causes of chronic illness β combining osteopathy, advanced testing and personalised lifestyle medicine for lasting results.
Functional Medicine is an integrative, science-based approach to healthcare that investigates why you're unwell β not just what to call it. Rather than managing symptoms, it looks at the interactions between genetics, gut health, hormones, nutrition, environment and lifestyle to find the underlying drivers of chronic illness.
It combines the best of conventional medicine with natural therapies β using advanced diagnostic testing, detailed health history and a systems-biology framework to create a genuinely personalised treatment plan that goes far beyond what a standard GP appointment allows.
Functional Medicine is particularly powerful for people who have been told "your tests are normal" or "you'll just have to live with it" β and who know there must be more to the story.
Using advanced testing, scientific insight, and holistic principles β we create tailored treatment plans that support your body's natural ability to heal.
Our Functional Medicine approach integrates evidence-based medicine, holistic care and prevention β always personalised, never generic.
Comprehensive laboratory and functional testing β hormones, gut microbiome, food sensitivities, nutrient levels, inflammation markers and more.
An in-depth intake covering your full medical history, lifestyle, nutrition, sleep, stress and current symptoms. We look for connections between everything.
A customised treatment plan covering nutrition, targeted supplementation, sleep optimisation, stress management and exercise β reviewed and refined over time.
We work alongside your GP and other specialists β and integrate with Premier Wellness osteopaths, acupuncturists and nutritionists for truly comprehensive care.
Tonia Peachey is Auckland's most comprehensively trained Functional Medicine Osteopath β and one of the few practitioners in New Zealand trained by the Institute for Functional Medicine (IFM), the world's leading Functional Medicine education body.
With over 15 years in clinical practice and a Master of Osteopathy from Unitec, Tonia has spent her career working with people who have complex, long-standing conditions that conventional medicine alone hasn't resolved. She fundamentally rejects the idea that patients must simply "live with it."
Her clinical approach combines hands-on osteopathic treatment with Functional Medicine β a systems-biology framework that investigates the root causes of illness by looking at the interactions between injuries, genetics, lifestyle, gut health, hormones and environmental factors.
Tonia consults in-person at our Glenfield and Orewa clinics, and offers Functional Medicine consultations via telehealth for patients anywhere in New Zealand.
Tonia asked in-depth questions and got my whole history β she wanted to know everything, and I could tell she was looking for links between all my symptoms, something no one else had ever done. She educated me about the link between long-term stress and the effect on my whole being. Tonia not only treated my symptoms, but looked further to find the underlying causes β no doctor has ever done this for me. It has turned my life around.
After being in a car accident, my body was a bundle of complex injuries no one knew how to untangle. Tonia met me with empathy, practicality, and a real understanding of what mattered most. Her blend of osteopathy, functional medicine, and holistic care has made a profound difference. And since starting treatment with her, I haven't had a single migraine. Tonia is, without question, the most amazing practitioner I've ever met.
I was a mess when I first went to see Tonia. What a blessing it was to find the best from the start! After a few weeks, it was glaringly obvious how the quality of my life had improved. Thank you for always going the extra mile, Tonia and team.
