Why should an organisation commission an independent health and safety incident investigation?

An independent investigation removes internal bias, ensures a rigorous root-cause analysis, and demonstrates to regulators like WorkSafe NZ that the PCBU is acting with proactive due diligence. It prevents the investigation from devolving into a "blame game," ensuring that systemic, organisational failures are actually identified and fixed.

Can IMPAC work directly with our legal counsel?

Yes. IMPAC frequently partners with legal teams on a confidential basis under legal privilege. We provide expert liability assessments and strategic support following a severe workplace incident, ensuring your legal strategy is grounded in operational reality.

Independent Health and Safety Incident Investigation Services

When a catastrophic event occurs on your site, internal panic sets in. If your organisation treats an incident investigation as a frantic exercise in assigning blame or protecting reputations, you guarantee that the exact same disaster will happen again. Concluding an investigation report with "operator error" and a mandate to "re-train the worker" is a complete failure of leadership. It serves only to cover up the broken organisational systems that allowed a fatal decision to be made in the first place.

At IMPAC, we provide the uncompromising, independent expertise required when things go badly wrong. We deploy rapid, expert intervention to deal with the regulator, support your legal team, and conduct a rigorous health and safety incident investigation that exposes the systemic rot underlying the event.

Immediate response and expert support

The first 24 to 48 hours following a serious workplace incident are critical. Evidence disappears, witness memories distort, and the operational fallout can paralyse a business. You need fast, experienced help to secure the scene, manage the immediate risk, and navigate the intense scrutiny of WorkSafe New Zealand.

With over two decades of experience responding to critical incidents across New Zealand's highest-risk industries, IMPAC steps into the chaos. We act as an independent authority, bringing immediate structure to the response. We ensure that your immediate actions do not inadvertently compromise the investigation or increase your legal exposure under the HSWA 2015.

Managing a health and safety incident investigation

Internal investigations naturally suffer from bias, defensive posturing, and a reliance on "how we've always done it." An independent health and safety incident investigation from IMPAC removes that bias entirely.

Our primary purpose is to give your Board and executive team the unvarnished truth. We don’t just hand over a descriptive report of what happened; we deliver a thorough, expert analysis of the root causes. We interrogate the exact failure of your critical controls and provide uncompromising, actionable guidance on what must be done to prevent reoccurrence. This independent verification demonstrates to regulators that you are taking the incident seriously and acting with genuine due diligence.

The IMPAC approach: Rejecting the "worker error" excuse

A common and fatal flaw in New Zealand incident reporting is stopping the investigation the moment a frontline worker's mistake is identified.

If a worker makes a mistake that leads to a catastrophic incident, it means your organisational controls failed to mitigate that error. Our experience-led approach drills deeper. We investigate whether your workers were too busy mired in the minutiae—ignoring critical risks because the prospect of absorbing a 50-page safety manual relegated the idea of H&S to a pointless burden. We use proven, advanced investigation methodologies to move beyond superficial fixes, ensuring that the new controls you implement meet the HSWA 2015 standard of what is genuinely "reasonably practicable."

Legal liability and expert witness support

When an incident results in severe harm or regulatory prosecution, you need to know exactly where you stand. IMPAC’s senior consultants integrate seamlessly with your organisation's legal counsel to manage your exposure.

Legal liability assessments: We work on a confidential basis under legal privilege to provide your legal team with an unvarnished assessment of your potential liability, allowing you to plan your legal strategy accordingly.
Expert witness support: If the matter proceeds to Court, you require independent, authoritative testimony. Our expert witnesses provide formal opinions for the prosecution or the defence on exactly what constitutes "reasonably practicable" steps under the HSWA 2015—providing the deep operational context that lawyers and judges rely upon.

Do you provide support before an incident occurs? Absolutely. Beyond post-incident response, IMPAC can proactively evaluate your current frameworks, develop your internal investigation processes, and train your staff to handle incidents effectively before they ever happen.
