Vice President: Michael Brown

Biomedical Services Technician, Canterbury District Health Board

Born in Christchurch but raised in Blenheim, I call Christchurch home. It’s here that I live with my wife Glenys and our children.

I originally started my career as an electronics technician for a Wellington company, manufacturing foreign object detection equipment for the food and textiles industry.  Having attained the position of Senior Service Engineer, I left that company to spend three years driving tour coaches all over Europe and the UK.

When I had enough of living out of a backpack, I returned to Christchurch. After a few years specialising in industrial XRay, metal detection and weighing systems, I started working for the CDHB. As a Biomedical Services Technician, my specific areas of responsibility include the Emergency Department, Resuscitation Equipment, Rural Hospitals and numerous clients outside the hospital. I am passionate about my job and relish the fact that I am able to use my skills and enthusiasm working alongside other medical professionals to improve patient care. It excites me that, having worked for more than 10 years in this field, I am still constantly learning new things, and working on new equipment.

Outside of work, I enjoy breeding quail and spending time exploring the outdoors with my family.

I am excited about what the future holds; Christchurch following the earthquakes is turning into an amazing city and with a rapidly developing health service, the DHB is a stimulating and interesting place to work.


Past President/Treasurer: Zane Lee

Zane started out studying an NZCE Electrical while working as a Biomed in Auckland.  He then moved on to do the obligatory OE and continued to be a Bio med in London for 3 years. Upon his return to Whangarei, where he was born and bred, he worked at the NZ Refining Company fixing all things electrical/electronic. After spending 3 years doing this it was time to start a Biomed company of his own. This he grew to include over 18 Staff and fix not only medical equipment, but he also ran a team of electricians. Zane spent the next 14 years repairing, installing and compliance testing medical equipment from Cape Reinga to Auckland.  During this time he got married to Juliet and had two wonderful boys Josh and Morgan. The next stage of his life would lead him to Christchurch where he has been with his family since the end of 2018.

My Hospital career started in 1970 at West London Hospital and moved to the New Charing Cross Hospital in 1972, before emigrating to New Zealand in 1973. After a 3 year stint at the Ministry of Works and Development, I joined the Auckland Hospital as Assistant Engineer in 1977 and also joined the Institute that year.  I moved to Waikato Hospital in 1981 where I stayed until I retired in 2007.

Warren Crawley

Technical Services Engineer, Spotless Services, Palmerston North Hospital

I commenced my working life with the Signals Division of New Zealand Railways being involved with all major signalling and electrical project in the Central North Island including earthing and bonding site engineer for the Marton to Te Rapa section of the NIMT Electrification Project.  I left the Railway during the downsizing of the 1980s and joined the Health Service as Hospital Engineer at Wanganui Hospital working under Chief Engineer Barry Hobson.  After the establishment of Crown Health Enterprises, I transferred to Palmerston North as an Electrical Engineer working for Chief Engineer Peter Stevenson.

The political changes of the mid-1990s saw our Facilities and Clinical Engineering functions contracted to Spotless Services who have been my employer since then.  This resulted in a range of opportunities including work in the USA, Australia and Antarctica.  My current role is Technical Services Engineer based at MidCentral District Health Board.  I am currently a member of a number of Standards Committees.  Outside of Health Engineering, I have completed 24 years with St John reaching the qualification level of Upskilled Paramedic having been involved in every aspect of ambulance work.  I have a keen interest in Tramping, and Amateur Radio.  I completed a Master of Technology in 2014.

I started work as an industrial electrician apprentice at British opes/Bridon Wire in the UK.
After almost 14 years I took a role as an electrical and electronics instructor for a couple of years before meeting my future Kiwi wife Belinda and moving to New Zealand where I took on an electrical supervisory and engineering role for Unilever at their food processing facility in Hastings.
I was recruited by the then Wellington Area Hospital Board in early 1990 and remained there until retirement from Capital & Coast DHB in early 2020.
During my almost 30 years there I have been involved with virtually every aspect of building and facilities electrical and control infrastructure including autoclaves, PABX’s, data and fibre installs, Building Management Systems, medical gas systems and alarms, 11kV electrical systems and generators and lots more.

My name is James Henderson, founder and director of New Zealand Validation Services.  While I started my career as an electrician working in DHB’s, I quickly progressed into other specialised areas, working in surgical hospitals and other companies throughout New Zealand.

Secretary: Kevin Miller

Associate – Built Environment and Electrical Engineer, Aurecon.

I believe the most important aspect of any design is the human one. Whether it be building occupiers, works managers, maintenance staff or fellow design team members, I believe our primary focus should be on improving the lives of those around us. This includes how we work together to deliver projects through to the impact the finished product has on those who interact with it.

The projects I enjoy most are those that are unique or complex. The challenge is in taking a complex problem and working with the Client to devise a solution which is simple, easy to use and maintain and provides a good environment to enhance the productivity of the end-users.

I have particular experience and expertise in the design of healthcare facilities. These projects combine the complexity of high integrity power systems with the need to create a good environment for staff and patients requiring a high degree of user interaction. I also have experience in a wide range of other specialist facilities such as trading banks, airports, broadcast centres, industrial workshops, data centres etc.


Membership: Karsten Maertzschink

Service Manager, Clinical Engineering, ADHB.

I would describe myself and leadership style as someone who is authentic, a talent advocate, as well as being actively involved in the day-to-day business. As an authentic leader, I believe I am recognised as someone who is sincere, genuine, and most importantly, has a passion and interest in leadership. As a talent advocate, I am constantly assessing individual’s capabilities, how to attract the right people, and how to develop them, but most importantly, how to help those I lead to be successful in their chosen career. To be actively involved in the business, I’m constantly seeking knowledge about how to run a sustainable business which foremost looks after our customer’s needs. So leadership, to me, is an on-going learning journey.
