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.

Pieter Buisman


I was born and raised mainly in the centre of the Netherlands.  With all types of nature close to each other, it is a great place to grow up.  After years of education and gaining some working experience abroad, I finished my GP training in 2020.

My interests are broad and I would describe myself as an all-round GP.  I enjoy all aspects of general practice.  My focus is to help and guide patients further with their symptoms, questions or uncertainties.  I find it desirable to incorporate diverse aspects of life in the evaluation and treatment of diagnoses.  For me, it is important to appreciate the complexity of the human body and I strive to identify the most impactful causes of the presented request for help.

Besides work I enjoy quality time with my family and friends, baking cake/bread and being in the outdoors; where you will find me jogging, scuba diving or climbing some hill.

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 healthcare 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 cellphone 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 continue 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 on to Greenwood in 2008.

From 2018 for 2 ½ 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.

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

David Short


Born in Dannevirke in rural Tararua country I moved to the South Island for school and never left. I now consider myself a mainlander and have settled in sunny Tasman with my wife and children.

Prior to starting medicine I completed an honours degree in Molecular Biotechnology through Otago as well as a certificate in Outdoor Recreation through Tai Poutini Polytechnic on the West Coast.

I have been a doctor for over ten years, working in a number of hospitals in the South Island while completing my specialist training in Rural Hospital Medicine. I am currently splitting my time between a hospital job at Te Nikau in Greymouth and GP work at Greenwood. My interests in medicine include older person care, general internal medicine, cardiology, acute care and wilderness and remote medicine.

Outside of work I keep balance by enjoying the hills and beaches with my family.

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

My husband and I enjoy getting out to Abel Tasman on our launch and making the best of what this wonderful region has to offer.

Missing not having enough time with the kids or time to explore New Zealand, we decided in 2020 to move to Motueka Valley and this beautiful part of New Zealand.
When presented with the opportunity, to get back to working in the healthcare sector as a Health Care Assistant I just couldn’t resist.
I enjoy caring for people and always give my best to help.

Originally from Invercargill, I started my career in health after graduating from Otago University in 2008 with a Bachelor of Physical Education and Management.

After many years working in PHO’s I am excited to now be back working in the frontline, supporting the busy world of General Practice.
