August 4, 2025

Forestry is one of New Zealand’s highest-risk industries, with machinery-related incidents continuing to feature prominently in serious harm statistics. At DEG Consulting Engineering, we specialise in designing and certifying forestry machinery that meets the operational demands of the sector while aligning with New Zealand’s health and safety legislation and recognised standards.

**Regulatory Framework**

Forestry machinery design is governed by a combination of statutory obligations, codes of practice, and technical standards. Key requirements include:

- **Health and Safety at Work Act 2015 (HSWA)**  
  Establishes the duty of care for all Persons Conducting a Business or Undertaking (PCBUs), including designers, manufacturers, and operators of forestry machinery.
- **Approved Code of Practice for Safety and Health in Forest Operations (ACOP)**  
  Provides practical guidance for meeting obligations under HSWA, particularly in harvesting, silviculture, and log transport operations.
- **Relevant AS/NZS and ISO Standards**, including: 
    - AS/NZS 4024 series – Safety of Machinery
    - AS 1636 and ISO 3471/3449 – Roll-Over Protective Structures (ROPS), Falling Object Protective Structures (FOPS), and Operator Protective Structures (OPS)
    - AS/NZS 1418 – Cranes and lifting components
    - AS 4991 – Lifting Devices
    - AS/NZS 1657 – Fixed platforms, walkways, stairways and ladders

**Safety-Critical Design Elements**

DEG’s forestry machinery designs incorporate the following safety features, each referenced to applicable standards:

| **Component** | **Safety Feature and Compliance Reference** |
| --- | --- |
| Operator Protection | ROPS, FOPS, OPS certified to ISO 3471/3449; COPS integrated where required |
| Access and Egress | AS/NZS 1657-compliant platforms, handrails, and anti-slip surfaces |
| Hydraulic Systems | Fail-safe design with pressure relief and lockout mechanisms |
| Lifting Attachments | AS 4991-rated spreader beams, lifting lugs, and anchor points |
| Fall Protection | Integrated anchor points for fall arrest and restraint systems |

**Documentation and Audit Readiness**

All DEG designs are supported by comprehensive documentation to ensure audit defensibility and operational clarity:

- Engineering certification and load rating documentation
- Compliance matrices mapped to HSWA, ACOP, and AS/NZS standards
- Maintenance and inspection schedules aligned with ISO/IEC 17020 and 17025
- Design drawings and modification records with full traceability

**Why Safety-Led Design Matters**

New Zealand’s forestry sector continues to face scrutiny over workplace safety. Machinery design plays a critical role in reducing risk and ensuring compliance. By embedding safety into the design phase, DEG helps clients:

- Meet WorkSafe NZ expectations
- Reduce liability exposure
- Ensure defensibility in audits, investigations, and contract reviews

DEG Consulting Engineering delivers forestry machinery solutions that are safe, compliant, and built for New Zealand’s unique operating environments. Whether designing new equipment, modifying existing assets, or certifying lifting gear, we provide technical assurance backed by regulatory precision.
