Healthspace is a small general practice in New Plymouth that currently employs two experienced doctors. Along with a team of nurses, a naturopath and medical herbalist and admin/reception staff.
We provide primary medical services whilst integrating a ‘whole person’ approach to patient care. We are passionate about utilising a functional medicine philosophy to our care.
We look for underlying causes and contributors to ill health and disease. Our clinic embraces a preventative, personalised and partnered approach with patients and we focus on blending conventional medicine with nutritional and lifestyle options.
We also have appointments for non enrolled patients, following the same philosophy. .

Dr Carey Martin
MBChB DipObs DipPaeds DipHSc (Herbal Medicine) FRNZCGP FACNEM MPhEd BSc
Dr Martin graduated from Auckland Medical School in 1992, having previously been to Otago University and having worked in both academic research and market research fields. Her hospital years as a House Surgeon were at Taranaki Base Hospital and it was there that she completed post graduate diplomas in Obstetrics and Gynaecology and Paediatrics. She started training as a GP in Wellington and worked as a locum there in 1996-1997. In mid 1997, she moved back up to New Plymouth to start her first general practice.
Her journey as a GP quickly led her down the functional and integrated medicine pathway as she realised many people were not getting better with the conventional approach. She realised it was the underlying causes of illness that were important and that healthcare ‘just had’ to address these.
Dr Martin is passionate about keeping up to date with medicine related sciences and continues to learn as much as she can. She regularly attends, in person or virtually, local, regional, national and international medical educational webinars, meetings and conferences. This includes regular GP training as well as functional/integrative medicine, nutritional/herbal/lifestyle medicine events.
Dr Martin loves off road running, mountain biking, tramping, snowboarding, and will get into the mountains where ever she gets the opportunity. Her passion is orienteering which she has competed in for 30 years and she continues to attend orienteering events nationally and overseas.
