Dr Luisa Arias - GP/Director


Originally from Colombia, I did my medical training in its capital, Bogota. After graduating, I worked in Colombia as a GP for four years before moving to New Zealand in 2006, where I trained in General Medicine at both Taranaki Base Hospital and Waikato Hospital. I have been working in general practice for the last five years and became a Fellow of the Royal New Zealand College of General Practitioners in July 2017. 

I am married to a New Zealander and have one child. We have been proud Waikato residents for the last seven years and we love it here.

I have a special interest in adult medicine and chronic long-term conditions. I believe having a trustful and respectful relationship with my patients is very important. Every day I work to provide the best possible care for my patients.

Dr Arias works Monday, Tuesday, Wednesday and Friday

Dr Shama Padayachey - GP

MBBCh (WITS) MCFP (SA) MFAMMED (WITS) Vocationally Registered in NZ

I am from South Africa. I graduated with my medical degree from the University of Witwatersrand and after graduating I soon realised that my passion in medicine was deeply rooted in Family Medicine. I obtained my MCFP from the Colleges of Medicine of South Africa and my MFAMMED from the University of Witwatersrand. I am vocationally registered as a GP specialist in New Zealand.

I arrived with my family in New Zealand in September 2020. We are really excited to be in New Zealand and we are enjoying living in Cambridge and love the warm Kiwi hospitality – ‘it is one of its kind’.

I believe that working in general practice allows me the unique opportunity to provide health care to patients and their family within the context of their home and work environment. Managing the health needs of my patient is a joint partnership between doctor and patient, which lends itself to successful health outcomes.

I have a special interest in chronic medical conditions, mental health and preventative health.

Dr Shama works Monday, Tuesday, Thursday and Friday.

Dr Christina Benson - GP


I was born and brought up in Scotland, completed my first degree in Physiology from the University of St Andrews and then went on to study Medicine at the University of Dundee graduating in 1999. In 2003 I completed my GP training and gained membership to the Royal College of General Practitioners. I have since then continued to work as a GP both in the UK and New Zealand.

My family and I first came to New Zealand in 2007, where we lived and worked in Hawkes Bay. We returned to the UK in 2011 but quickly concluded that New Zealand had left a lasting impression and was the best place to live and bring up our family. In 2017 we returned to the Waikato and have resided in Cambridge ever since. My husband Drew is Medical Director for Chronic Conditions and Cancer Medicine at Waikato Hospital, and we have 2 children who keep us very busy. My special areas of interest are, Women’s Health, in particular Family Planning - including IUD insertions and Mental Health.

I feel that as GPs we are very privileged to know our patients and their families for many years and that the care we provide must always be of the highest standard. It is important that the care provided should be holistic in nature considering all aspects of patients and their family’s needs.

Dr Benson works Monday, Wednesday and Friday mornings.

N.B. as New Zealand is in the early stages of registering PAs as a medical profession, there are limitations on their scope of practice. All PAs’ work at Cambridge Family Health is checked and signed off by a GP.

Carla Mitchell-Davidson - Practice Manager

I was born and raised in Cambridge and returned here after living overseas for 15 years. I have been working at Cambridge Family Health since it opened in 2015.

I started as a receptionist and a few years later decided I wanted to further my skills so I studied to become a Primary Care Practice Assistant. This role was very fulfilling and I particularly enjoyed the patient care it involved and assisting the Doctors and Nurses. I stepped away from that role and became Practice Manager in 2021. I am looking forward to continuing to deliver a high standard of customer service and working alongside the amazing staff we have.  

My husband I have three boys who keep us very busy. I enjoy spending time with my family and friends and love watching my children play sport.
