Nadia Turnbull
Nurse Extraordinaire – I.V. Boutique Integrated Health
Hey there, lovely people! I’m Nadia Turnbull, and I’m thrilled to bring over 14 years of nursing experience to the wonderful world of I.V. Boutique Integrated Health.
My journey in nursing has taken me through various realms – from mental health to pediatric care, community health, and beyond. But what truly lights up my soul is my passion for alternative medicine. I’ve always believed in exploring holistic approaches to wellness alongside traditional practices.
With qualifications ranging from a Post Grad Diploma in Mental Health to a PG Certificate in Well Child/Tamariki Ora nursing, along with a Diploma in Natural Health and Nutrition.
In progress: SCOPE certification, endorsed by the World Obesity Federation.
I’m constantly expanding my knowledge. And hey, the learning never stops – there’s always something new to discover!
But what truly makes my heart sing is the people I meet through my work at I.V. Boutique Integrated Health. The conversations, the connections, some sad times but also the shared laughter – it’s these moments that make every day a joyous adventure.
I feel incredibly blessed to be part of this amazing journey, helping each of you thrive on your path to wellness. All of us I.V Boutique Integrated Health aspire to help and heal whenever possible. That’s what makes us a great team!
Dr. Stephan Neff
MD, FANZCA
Dr. Stephan Neff is a licensed medical doctor in New Zealand and a retired specialist anaesthetist (MD, FANZCA) with extensive experience in pain medicine (FFPMANZCA) and perioperative care. Over time, his deep interest in understanding the root causes of health and disease led him to pursue functional medicine. He is a proud member of both the Institute for Functional Medicine (IFM) and the Australasian College of Nutritional and Environmental Medicine (ACNEM).
Functional medicine allows Dr. Neff to approach health by seeing the whole person—not just isolated symptoms. This patient-centred model focuses on uncovering the underlying imbalances driven by lifestyle, environment, and genetics. It has not only transformed how he supports others but has also deeply inspired his own journey of growth and healing.
Driven by curiosity and personal transformation, Dr. Neff expanded his training to include breathwork, yoga-based flexibility coaching, life coaching, and clinical hypnotherapy. These complementary disciplines enable him to guide others with a truly integrative, mind-body approach to well-being.
As an author, speaker, and podcast host, Dr. Neff is passionate about breaking the stigma around mental health and empowering people to create meaningful, sustainable change through habit, mindset, and self-awareness.
His mission is to help individuals reclaim their vitality and, together, contribute to a healthier, more conscious world.
