About Shiftwork Services

We believe that shiftworkers face challenges that require solutions such as shiftwork lifestyle training, sleep and fatigue management and coaching. Since 1995 we have worked in partnership with New Zealand organisations to help improve health, safety and productivity in the 24/7 workplace.


Fiona Johnston


Fiona Johnston trained as an occupational therapist and has worked in the mental health and concussion services in New Zealand for over 25 years helping clients sleep better, manage fatigue and improve work-life balance.

In 1995 she founded Shiftwork Services and focused on helping shiftworkers live a little better and managers develop a safe and productive workforce. In 1998 she partnered with InterDymics to offer clients a risk based, bio-mathematical approach to managing workplace fatigue. This mix of delivering a validated way of assessing fatigue with personal preferences has become popular with many clients especially those in high risk industries.

Fiona is an author, popular key note speaker, and coach on all matters associated with sleep, rostering, fatigue, shiftwork and well-being.
