NZ Health and Safety at Work Act Documentation
The Health and Safety at Work Act 2015 creates extensive documentation obligations for New Zealand businesses. Learn how to maintain compliant safety documentation.
The Health and Safety at Work Act 2015 (HSWA) is New Zealand's primary workplace health and safety legislation. It places duties on Persons Conducting a Business or Undertaking (PCBUs) to ensure, so far as is reasonably practicable, the health and safety of workers and others influenced by the work. WorkSafe New Zealand is the primary regulator, with industry-specific regulators for maritime, aviation, and some other sectors.
Documentation is fundamental to HSWA compliance. The Act and its associated regulations require PCBUs to identify hazards, assess and manage risks, and maintain records that demonstrate how they are meeting their obligations. When WorkSafe investigates incidents or conducts inspections, documentation is the primary evidence of compliance.
PCBU Documentation Obligations
Risk Management Documentation
The cornerstone of HSWA compliance is a documented risk management approach:
| Requirement | Documentation | Regulatory Basis |
|---|---|---|
| Hazard identification | Hazard register covering all foreseeable workplace hazards | HSWA s30; Health and Safety at Work (General Risk and Workplace Management) Regulations 2016 |
| Risk assessment | Risk assessments for each identified hazard using a recognised methodology | General Risk and Workplace Management Regulations |
| Control measures | Documented control measures following the hierarchy of controls | HSWA s30 |
| Monitoring and review | Records of monitoring the effectiveness of controls and reviewing risk assessments | HSWA s30 |
Worker Engagement and Participation
HSWA requires PCBUs to engage with workers and provide opportunities for participation in health and safety matters:
- Worker participation practices: Documented approach to worker engagement, whether through health and safety representatives, health and safety committees, or other agreed practices
- Health and safety representative elections: Records of elections, training, and the exercise of representative functions
- Health and safety committee minutes: Where a committee is established, records of meetings, decisions, and actions
- Consultation records: Evidence of consultation with workers on health and safety matters, including changes to the workplace, work practices, or procedures
Notifiable Event Management
PCBUs must notify WorkSafe of notifiable events (deaths, notifiable injuries or illnesses, and notifiable incidents). Documentation requirements include:
- Notification records: Evidence that WorkSafe was notified as soon as possible after becoming aware of the event
- Scene preservation records: Documentation of steps taken to preserve the incident scene
- Investigation records: Records of internal investigation including root cause analysis
- Corrective action records: Documentation of actions taken to prevent recurrence
- Review records: Evidence that risk assessments and controls were reviewed following the event
Regulation-Specific Documentation
General Risk and Workplace Management Regulations 2016
These regulations create specific documentation requirements for workplace facilities, first aid, remote and isolated work, and personal protective equipment:
| Area | Documentation Required |
|---|---|
| Facilities | Records demonstrating that facilities are adequate for workers |
| First aid | First aid plan, first aid equipment records, first aider qualifications and training |
| Emergency planning | Emergency plan, evacuation procedures, testing and drill records |
| Remote work | Risk assessments for remote and isolated work, communication procedures |
| PPE | PPE assessments, provision records, training in use and maintenance |
Hazardous Substances Regulations 2017
Businesses that use, handle, or store hazardous substances must maintain:
- Hazardous substances inventory
- Safety Data Sheets (SDS) for all hazardous substances
- Exposure monitoring records
- Health monitoring records for workers exposed to certain substances
- Emergency response procedures for hazardous substance incidents
- Training records for workers who handle hazardous substances
- Certified handler records where required
Asbestos Regulations 2016
For workplaces where asbestos has been or may be present:
- Asbestos register identifying the presence, type, and condition of asbestos
- Asbestos management plan
- Records of asbestos monitoring and sampling
- Worker exposure records (retained for 40 years)
- Records of asbestos removal work including clearance certificates
Common Documentation Failures
Reactive Rather Than Proactive Documentation
Many businesses create safety documentation only after an incident or WorkSafe inspection. HSWA requires a proactive approach where hazards are identified and risks are managed before harm occurs. Documentation that only records incidents without demonstrating ongoing hazard identification and risk management does not meet the standard.
Generic Risk Assessments
Risk assessments that are generic templates rather than specific to the workplace, work activities, and conditions. WorkSafe expects risk assessments to reflect the actual hazards and circumstances of the specific workplace and work being performed.
Insufficient Worker Consultation Evidence
HSWA places strong emphasis on worker engagement and participation. Documentation that shows policies were created without worker input, or that health and safety decisions are made without consulting affected workers, indicates a failure to meet the engagement obligations.
Training Records That Show Attendance Only
Training records that record attendance at a session but do not document what was covered, whether competency was assessed, or whether the training was relevant to the worker's actual tasks. WorkSafe expects training to be relevant, adequate, and assessed for effectiveness.
Outdated Emergency Plans
Emergency plans that were created when the business was established but have not been reviewed, updated, or tested. Emergency plans must be current, reflect the actual workplace layout and hazards, and be regularly tested through drills.
Building a Safety Documentation Review Process
Monthly Reviews
- Hazard register reviewed and updated for new or changed hazards
- Incident register reviewed for completeness and corrective action follow-up
- Training records checked for upcoming qualification expiries
- First aid supplies checked and documented
- Hazardous substances inventory reconciled with substances on site
Quarterly Reviews
- Risk assessments reviewed for currency and adequacy
- Worker consultation records reviewed for genuine engagement evidence
- Emergency plan reviewed against current workplace conditions
- Health monitoring records reviewed for workers exposed to specific hazards
- Subcontractor and contractor safety documentation verified
Annual Reviews
- Full review of health and safety management system documentation
- All policies and procedures reviewed and updated
- Emergency plan tested through drill and reviewed
- Worker participation practices reviewed and refreshed
- Annual health and safety performance reported to governance
How Content Review Tools Support HSWA Documentation
New Zealand businesses maintain extensive health and safety documentation across hazard registers, risk assessments, policies, procedures, training records, and incident reports. Ensuring this documentation is current, complete, specific, and consistent is an ongoing challenge that grows with business complexity.
Content review platforms can systematically check safety documentation against HSWA requirements, flag generic language that suggests template-based rather than site-specific assessments, verify that risk assessments address the hierarchy of controls, assess whether safety procedures are written in clear language accessible to all workers, and identify outdated references or superseded regulations. By configuring review criteria based on HSWA and WorkSafe guidance, health and safety teams can maintain documentation quality at scale.
This does not replace the expertise of qualified health and safety professionals who must assess whether controls are adequate for specific hazards. But it provides a consistent documentation quality check that catches common gaps before they become WorkSafe findings.
