President: Michael Brown

Biomedical Services Technician, Te Whatu Ora Waitaha Canterbury

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 started my career as an electronics technician for a Wellington company that manufactured 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 of specialising in industrial X-ray, 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, and acute services. I am passionate about my job function and love that I can use my skills and enthusiasm to work alongside other medical professionals to improve patient care. It excites me that, having worked for more than 15 years in this field, I am still constantly learning new things, and working on new equipment.

Outside of work, I enjoy bird-keeping and spending time exploring the outdoors.

I am excited about what the future holds; Christchurch, after the earthquakes, is turning into a fantastic city. With a rapidly developing health service, Te Whatu Ora is an exciting and interesting place to work.

Treasurer: James Henderson

Director at New Zealand Validation Services Ltd

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. 

I am a qualified CSSD Technician, a Registered Electrician and an expert in sterilisation validation, with over 12 years of experience working in the medical industry. ​Before setting up NZ Validation Services, I held an executive role as a Property and Services Manager at a leading Private Surgical Hospital. 

With a true passion for sterilisation and infection control, I set up New Zealand Validation Services, offering tailored solutions to clients across NZ and the Pacific.  

My holistic approach, technical expertise and solution-driven philosophy make me stand out from the rest. 

Out of work, I love spending time with my family and working away on projects on our small block.  I enjoy mountain biking, whenever I get a chance. 

Membership: Karsten Maertzschink

Service Manager, Clinical Engineering, ADHB.

I would describe myself and my leadership style as authentic, a talent advocate, and 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 individuals’ capabilities, how to attract the right people, and how to develop them, but most importantly, how to help those I lead succeed in their chosen careers. To be actively involved in the business, I’m constantly seeking knowledge about running a sustainable business that looks after our customer’s needs. So leadership, to me, is an ongoing learning journey.

Estimating Manager – Facilities and Asset Services | Downer NZ Ltd

I have spent my career in the construction industry, spending 15 years on a wide range of residential and commercial projects as a Quantity Surveyor.
In 2018, whilst working on a construction project at MDHB, I had the opportunity to dive into the facilities management world. I took on the role of Regional Facilities Manager for the Central Alliance at MDHB with Spotless Facility Services.
During this role, I was lucky enough to be mentored by Warren Crawley and exposed to the business end of facilities management. In this role, I was able to see the lifecycle of a building and appreciate the challenges that come with the long-term maintenance of key facilities.
I am currently the Estimating Manager at Downer NZ Ltd, where I oversee the pricing of all Hard and Soft FM contracts.
Outside of work, I love to spend time with my kids or working in my family business.

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 many other specialist facilities such as trading banks, airports, broadcast centres, industrial workshops, data centres etc.
