FENZ declined a broken back claim despite three supporting medical opinions

What documentation failure looks like at its worst

In September 2022, Hamilton senior firefighter Paloma Serville and her crew performed CPR and a four-person lift of a 140kg patient during an emergency callout. Serville hurt her back. It was initially misdiagnosed as a lumbar sprain. Almost three years passed before an X-ray revealed the real problem: a fracture in her spine.

By then the evidential trail had gone cold. Fire and Emergency New Zealand’s in-house Injury Management Unit declined her claim, characterising the injury as a pre-existing gradual process condition. A formal review under s134 of the Accident Compensation Act was scheduled for 10 September 2026.

What makes the case remarkable is the weight of medical opinion FENZ is pushing against. Spinal surgeon Dr John Ferguson, whom FENZ paid for Serville to see, wrote in June 2026 that he believed she should be covered for treatment as a result of her occupational injury. FENZ-appointed occupational physician Dr Chris Walls called the gradual-process characterisation “hard to sustain” in 2025. Orthopaedic spine surgeon Dr Hamish Deverall stated that lifting a 140kg person, even in a four-person lift, would easily be sufficient to injure the lumbar spine.

Two of those three doctors were FENZ’s own appointees. Its unit still said there was insufficient evidence to change position, and it is simultaneously pursuing her medical retirement. Her surgeon puts her chance of full recovery at 90% with surgery. She cannot get ACC cover for that surgery until the work-related claim is accepted.

This is not just a FENZ problem

Strip away the institutional drama and the core failure is one every employer with physical roles should fear: no contemporaneous record captured how the injury happened. When the fracture finally surfaced, causation had to be reconstructed from memory and retrospective inference. Even employer-appointed specialists could not manufacture certainty three years after the event.

EMA manager of employment relations and safety Paul Jarvie makes the point plainly. “It’s vital that businesses collect all this data,” he says of incident and near-miss reports, noting that low-level injuries often flag a more significant issue. That documentation cuts both ways. It protects workers by establishing what happened, and it protects employers by fixing the actual mechanism of injury before a dispute over causation ever arises.

The scale of what’s at stake

This is not a fringe risk. ACC’s Q2 2026 data records 82,530 new work-related claims lodged in the first six months of 2026 and 158,535 active claims costing $567,720,887. Construction led with 13,403 new claims year-to-date, ahead of manufacturing on 9,101 and agriculture, forestry and fishing on 8,750.

The aggregate cost is enormous. The EMA estimates that in 2025 workplace injuries caused 20.8 million lost working days and $8.7 billion in lost economic output, with ACC paying $3.1 billion in weekly compensation. Every one of those figures started as an individual event that, at the time, looked manageable.

The regulatory floor won’t save you

The proposed Health and Safety Bill has a gap that points straight at cases like Serville’s. Jarvie warns that strains, sprains and back injuries, the greatest cause of workplace injuries across all sectors, would not meet critical-risk criteria and so would not require formal identification or management. The most common injury category would sit outside the bill’s core framework.

For employers in physical industries, that is a warning, not a reprieve. If regulation won’t require a system for the injuries most likely to happen, building one anyway is the risk-management play.

What good practice actually returns

Early engagement pays. Businesses that stay in touch with injured staff and support a return to work achieve faster outcomes, retain skills and cut the cost of prolonged absence, Jarvie says. Guidance from BusinessNZ in 2024 showed an injured Southern Spars employee returning to full-time work within three weeks through modified duties and regular contact.

Contrast that with Serville. Nearly four years on, no surgery, facing medical retirement, fighting three doctors’ opinions through a formal hearing. FENZ, meanwhile, is under sustained institutional strain, having been found by the Employment Relations Authority in March 2026 to have breached good faith over a restructure affecting 840 roles, with the union’s income protection scheme repriced from September 2026 after claims outpaced premiums.

Whatever the legal outcome on 10 September, the human and institutional cost of this dispute dwarfs what a proper incident report would have cost to file in 2022. Incident reports are not paperwork. They are evidence, and evidence is what decides these cases.
