Nearly one in three career firefighters shows signs of mental ill-health. Over 40% of NZ Police members show signs of probable post-traumatic stress. The drivers are cumulative trauma exposure, organisational pressure, and a culture that still asks first responders to absorb what most workplaces are protected from. The response needs to be structural.
The evidence
~43%
of NZ Police members surveyed reported probable post-traumatic stress. 14% met thresholds for clinically relevant PTSD, against ~3% in the general population.

career firefighters in NZ met criteria for one or more mental ill-health indicators. 92.8% had at least one Potentially Traumatic Event exposure in the previous 12 months.

What it looks like
In Aotearoa's emergency services, burnout rarely shows up as classic exhaustion-plus-cynicism. It shows up as cumulative trauma, hazardous drinking, sleep disruption, relationship strain and, eventually, departures the workforce cannot afford. The research is now unambiguous: organisational and management factors are more strongly associated with mental health outcomes than the operational trauma itself.
The AUT study of NZ fire and emergency personnel published in 2025 found Major Depressive Disorder at 24%, Generalised Anxiety Disorder at 13%, probable PTSD at 13% and hazardous drinking at 68%, and a 2023 NZ Police survey found 69% of members had experienced traumatic incidents at work and 57% reported hazardous alcohol use. For senior leadership in Police, FENZ, Hato Hone St John and the wider responder community, the signal is in attrition, ACC psychological claims and sick leave, and debriefs plus an EAP alone won't close the gap. The drivers are structural, and the response needs to match.
The drivers
First responders absorb what other workplaces are protected from. The FENZ data shows 92.8% of career firefighters had at least one Potentially Traumatic Event in the previous 12 months. Dispatch and comms staff often have the highest cumulative exposure, hearing what attending crews see. The volume is the issue, not just any single incident.
The most important finding in recent NZ research is that organisational factors, including perceived support, accountability and management practices, are more strongly related to mental health outcomes than the trauma exposure itself. The way the organisation responds to its own people matters more than the work the work asks of them.
Rotating shifts, night work and disrupted recovery time produce sustained physiological strain. Hazardous drinking rates of 57 to 68% across NZ first responder populations are not a culture issue: they are a signal of unresolved distress and an absence of safer coping pathways.
How we help
3 Big Things works with first responder and emergency services organisations across Aotearoa. We hold a contract with NZ Police and we understand the operational realities of the work: shift patterns, post-incident protocols, the difference between operational trauma and organisational injury, the importance of confidentiality in a hierarchical command structure, and the cultural particularities of frontline emergency work.
Identify the organisational and operational drivers in your workforce with psychosocial hazard assessment aligned to ISO 45003 and WorkSafe NZ guidance, recognising that for first responders, the organisational factors are often the structural lever, not the operational trauma.
Equip leaders to support, not just supervise with coaching and capability development for tier 2 to 4 leaders: station officers, sergeants, watch managers, supervising paramedics. The leaders closest to the work have the largest single influence on wellbeing outcomes.
Provide registered-psychologist support that respects the culture with confidential clinical support delivered by psychologists experienced with first responder populations: trauma-informed, shift-aware, command-structure-aware, and complementary to your existing peer support and EAP arrangements.
We understand the operational, regulatory and Te Tiriti context of emergency services in Aotearoa. We design our work around it.
