Our GP Team

Greenwood Health has a large team of GPs comprising 5 permanent GP pairs, including one trio, who work together to provide continuity of care for our patients. We also have a Nurse Practitioner who provides Urgent Care appointments. Our doctors are all Fellows of the Royal NZ College of General Practitioners or are working towards this qualification.

Jen Naper


Graduating as doctor in 2012, I began training as a GP at the end of 2017 and have been with Greenwood Health since June 2018. I love General Practice as it gives me the privilege of empowering people to realise their own personal and individual wellbeing goals. I have postgraduate qualifications in emergency medicine, tropical medicine and women’s health and a strong interest in lifestyle medicine and mental health.

Originally from Ireland, my partner Henry and I came to New Zealand in 2013. I’m happiest when I’m swimming in the ocean, when my hands are dirty in the garden, or when I’m playing lively Irish tunes in a session. In my spare time I also enjoy yoga, mountain biking and learning Te Reo Maori.

Gusta van Zwieten


Born and raised in the Netherlands, I graduated as a medical doctor in 2014 at Maastricht University. Afterwards, I proceeded to qualify as a GP and completed a PhD research degree in ear, nose and throat medicine and neuroscience. During these years I was fortunate to have worked in several different countries, such as UK, Canada, Nepal, and Ghana.

My job as a GP provides a unique position to care for patients of all age groups, help and guide them with their specific needs, and build a trusting relationship over time. I find this variety of medical practice very stimulating and rewarding.

In October 2021 my partner Jan and I moved to this beautiful part of the world. We feel inspired by the Kiwi lifestyle and especially love to explore the outdoors, whether it be climbing, mountain biking, or tramping. I consider myself very fortunate to be part of the team at Greenwood health and am looking forward to meeting you.

Oliver Madigan


I grew up on the Otago Peninsula and graduated from the Otago School of Medicine in 2008. After moving from Dunedin with my young family I joined the team at Greenwood Health in 2013 and became a Fellow of the Royal New Zealand College of General Practitioners in 2015.

I enjoy all aspects of general practice, particularly children’s health and mental health. I am passionate about providing quality health care to the people of our region.

I love living in Motueka. I feel proud to be part of a practice that is actively involved in the training of the next generation of doctors and that is also solely locally owned and operated.

Suzanne Viveen


I was born in the Netherlands, where I completed my GP training and a specialisation in tropical medicine. Before my family and I found our home in Motueka in 2012, I worked in Columbia, providing medical aid to indigenous communities.

I am passionate about getting to know people, learning about their backgrounds, motives and aspirations. While I enjoy all aspects of rural general practice my special interests are travel medicine, rheumatology and woman’s health. I am a certified Yellow Fever vaccinator and I also work in the public rheumatology clinic twice a month.

Outside of work, I love spending time in the outdoors, and with my young family.

James Chisnall


I have been in the Nelson Region since graduating from Otago University in 2002. My wife and I love the region so much that we have never left. We have three young children, and enjoy the wonderful environment that Motueka offers to raise a family. I enjoy all aspects of General Practice. With a special interest in allergies, musculoskeletal medicine, and providing healthcare for children. I have completed extra paediatric training via a Diploma in Child Health at Otago and also hold a Post Graduate Certificate in Allergic Disease from the University of Western Sydney.

Catherine Vercammen


Having completed my medical training at the University of CapeTown, South Africa, I have worked in South Africa, England and Wellington as a GP. Since 2006, I have been fortunate to be able to call Motueka home and to be part of the team at Greenwood Health. I enjoy all aspects of primary health and have a particular interest in Paediatrics, having a diploma in Child Health. My other areas of interest are in Women’s Health and Care of the Elderly.

Kirsty Moore


I grew up in North Canterbury but Motueka has lured me in and now I don’t want to leave! I love to get out on my bike, or in my kayak, to explore all our local surrounds. Motueka provides the best work/lifestyle balance imaginable. I am happiest when my husband and I are out in the bush or on the water with no cell phone and a block of chocolate. I have a particular interest in Paediatrics and Women’s Health, doing postgraduate study in both during 2015. I look forward to meeting you as I start my journey at Greenwood Health.

Michael Brewer


Born in Taranaki my family soon moved to the South Island and really this is where I have remained. I graduated from Otago University in 1983 and started general practice in Motueka in 1991 initially in Riwaka then Pah St and since 2008 at Greenwood.

From 2018 for 2 and a half years I left Greenwood to experience work in different places. The highlight of this time was having  the privilege to work as a volunteer in Vanuatu and Nepal.

I am now back working in Greenwood trying to fill the fairly large shoes of Dr Martin Hudson who retired in 2020.

I have post graduate qualifications in sexual health , travel medicine and gynaecology.

Outside of work I love the outdoors enjoying tramping, biking and caving.

I have 2 adult daughters both of whom are living in Motueka so this is clearly meant to be my home.

Glenn Anderson


I am a UK trained GP with interests in asthma and chronic airways disease. I job share with Dr Colette Pienaar and have been working in Motueka since my arrival in NZ in 2002. I worship at Tasman Bible Church and my hobbies include physics, science fiction, music and photography. I am enjoying my newly acquired status of Grandfather.

Colette Pienaar


Trained at Pretoria University in South Africa, I qualified as a doctor in 1996. I worked in rural South Africa until we moved to Motueka in 2004. I attained my fellowship with the Royal New Zealand College of General Practitioners in 2013. I am interested in all aspects of general practice, but I especially enjoy skin cancer medicine and women’s health. My husband Willem is a dentist and works in the dental wing of Greenwood Health. We have three children. I recharge by reading good books, enjoying long walks on the beach, having friends around for a meal, and watching a good movie. In the community I am actively involved at Alive Church of Christ. My motto when practising medicine is the following: “The good physician treats the disease; the great physician treats the patient who has the disease”-William Osler

Sophie Mace (she/her)


From Nelson originally, I graduated from University of Otago as a doctor in 2012 and I have been at Greenwood Health since 2015.

I have special interests in women’s health including sexual/reproductive health, adolescent health, lifestyle medicine, and breastfeeding medicine. I have a postgraduate diploma in Obstetrics and Gynaecology (PgDipOMG) and doing further training in breastfeeding medicine. I also follow a Health at Every Size (HAES) approach to medicine.

I am a mother of 2 and enjoy gardening and cooking.

Tina Murphy

Urgent Care Nurse Practitioner

Having trained as a nurse in the UK, I have worked in both the UK and NZ. My career focused on Emergency Care, mainly working in emergency departments in public hospitals in both the UK and NZ. This is where I embarked on further training for the Nurse Practitioner qualification, which I have now held for the last 15 years.

Being a Nurse Practitioner enables me to independently provide a complete health care service to my patients, in the same way that a doctor does.

Having moved into urgent care in the community a few years ago, I have gained an additional love of looking after people within primary care. With my specialist interest in emergency and urgent care medicine, I have been providing exactly this service to the community and visitors to Motueka from Greenwood Health since 2017.

Away from work, the ability to bike, run, hike and tramp in the amazing part of NZ, plus basically sitting and chilling in this amazing place, gives me that perfect split of work and home life.

Catrien van Boxel

GP Locum

I have recently moved to Motueka from the Netherlands, where I graduated as a doctor at the Erasmus University of Rotterdam in 2008. After having worked in Emergency Medicine  and Youth Healthcare for several years, I went on to specialise as a GP in Amsterdam and completed my training  end of 2015.

I love the variety, versatality and depth of working as a GP. I find it very rewarding to ( hopefully) be able to help some of my fellow humans by good listening, showing a genuine interest  and applying a mixture of practical skills and scientific knowledge.  I enjoy all aspects of general practice (apart from too much paperwork  and bureacracy) and  have a special affinity with palliative care.

As we’d been dreaming of living in this beautiful part of the world, my family and I were more than happy  that I got the opportunity to work in the amazing Tasman region.

We, including my 2 children,  are delighted by all the natural beauty and outdoor opportunities this region has to offer  and like the  friendly atmosphere here.

I’ve always liked tramping and swimming but  I’ve recently embraced mountainbiking and bird watching as new hobbies.  Also, I have an interest in drama/theatre and movies.


Matthew Barns

GP Locum

I moved to New Zealand from the UK in 2017, and worked in Whangarei until recently. I chose general practice because I value whole-person care and love hearing people’s stories. My approach to medicine is open-minded and I enjoy being challenged. I have a particular interest in skin disease, which I have studied for several years.

I feel privileged to be joining the Greenwood team for part of the year. I have a few adventures planned before settling down when my kids reach school age.

Fast forward to 2021 and the position of Health Improvement Practitioner exists. It is the most rewarding role I have ever had.

Outside of work I have a busy family and a large garden to keep me busy. I like to do yoga, weight training and to try new things as a challenge. I enjoy getting outside for walks at the beach or in the bush, or catching up with friends for a cuppa.

I’m excited to now rise to the challenge of practice nursing in my home community here in beautiful Motueka.

Tania Scott

I have been nursing since the 1990s in multiple different hospitals in several countries and have loved the excitement of all the travel opportunities it has provided. The world is one exciting place.

Mostly I have specialised in Adult Critical Care, with a particular interest in Organ Transplants and Trauma.

Being a Practice nurse is new role for me, but I thoroughly enjoy the challenges it brings and being part of the local community.

I am new to this region and love the weather and the outdoor life it provides, it’s definitely a special part of NZ.

I started at Greenwood Health in 2017 as a member of the Admin team. After a brief stint away on the North Island, working with the greatest love of my life, horses, I returned and took up the position of Health Care Assistant, which I find challenging but immensely enjoyable. My favourite part of the job is when I assist the GPs with minor surgery. Outside of work my horses keep me busy and I enjoy spending time with them in this beautiful region.

Linda Dormer

Naomi Rosamond

Clinical Manager

After graduating from Sydney Nursing School at the University of Sydney in 2009 I worked primarily in operating theatres until a holiday to New Zealand made me realise a move was definitely in order. With my management experience I was lucky enough to secure the position of Nurse Team Leader at Greenwood Health in 2016. Practice Nursing has been a very enjoyable challenge and a change from a time when most of my patients were asleep. In 2017 I took on the new role of Clinical Manager and after completing a certificate in Travel Medicine from Otago the role of Travel Nurse. When not at work I enjoy exploring this lovely region, a good book or some hands-on building work.
