Once achieved, this unit standard will remain on the trainee’s NZQA Record of Achievement for life.

However, under the Health and Safety at Work Act 2015 (HSWA), all PCBUs must verify ongoing training and competency. This means trainees should expect regular assessments to ensure continued competency. Trilogy Training offers refresher options to meet these requirements.

This workshop is an onsite practical assessment conducted over 2 days, with tasks observed by a verifier and/or assessor. Trainees will complete three closures for the road environment, which include:

  1. Mentored Tasks
    • Installing a shoulder closure.
    • Installing a two-lane diversion (contra-flow).
  2. Final Assessed Task
    • Installing a Stop/Go alternating flow site.

Tasks assessed include:

  • TMP review and pre-departure checks.
  • Crew briefing and contractor induction.
  • Risk identification via site drive-through.
  • Accurate implementation, uplift, and unattended worksite provisions.

If required, a free watch day may be added before assessment to enhance readiness.
