What we do at Fit for Duty

We are committed to making a healthy and positive difference in people’s lives by diagnosing and treating OSA.

The National Sleep Foundation (USA) reports that sleep deprivation, not cancer or coronary illness, now constitutes the number 1 killer in the Western World.

It is estimated that 1/3 of the population will suffer from a sleep disorder during their lives while another 1/3 are dangerously sleep deprived.  Experts claim that sleepiness is 'the smoking gun of the modern age' and fear that unless we radically shift our attitudes towards sleep we are heading towards a medical meltdown.

Establishing if your employees have a sleep disorder, such as Obstructive Sleep Apnea, is critical. Not only can an individuals health be adversely affected if it goes un-treated, but the likelihood of a fatigue related accident greatly increases, putting not only themselves, but also their colleagues and the community at risk.


The Fit for Duty program was developed in 2013 by Rachel Lehen and has successfully screened and treated hundreds of people across New Zealand.

Due to the nature of the role, drivers involved in the commercial heavy transport sector, especially male drivers, experience and much higher incidence of OSA than the rest of the population. Screening studies completed in this sector (in NZ) over the last three years indicate that approximately 24% of male commercial drivers suffer from OSA, much higher than the reported national statistics of 9% for all adult males. The prevalence of OSA in this population is likely due to many drivers being overweight, older than the national average, experiencing long sedentary periods whilst driving, working extended hours, at times contrary to the body’s natural circadian rhythms, and having a poor diet whilst on the road.

Fit for Duty’s turn-key solution offers screening & assessment, diagnosis and treatment for employees in businesses operating in the safety critical realm.
