Comprehensive Traffic Control Planning for Roadworks,
Construction, and Events in New Zealand

What is a Traffic Management Plan (TMP)?

A Traffic Management Plan (TMP) is a site-specific road safety strategy that details how traffic flow will be managed around a construction site, event, or roadwork project. TMPs are mandatory for any road activity in New Zealand, ensuring public safety while minimising congestion.

A well-structured TMP includes

  • Risk assessments and hazard identification.
  • Traffic control measures include detours, stop/go signals, and lane closures.
  • Compliance with the New Zealand Guide to Temporary Traffic Management (NZGTTM).
  • Submission to the Road Controlling Authority (RCA) for approval.

By following a certified TMP, businesses can ensure worker and road user safety while keeping projects legally compliant.

Why Traffic Management Plans Are Essential

Traffic Management Plans (TMPs) play a vital role in ensuring the safety of road users and workers while maintaining traffic flow during construction, maintenance, or events. Without a structured plan, projects face delays, legal complications, and increased risks of accidents.

Compliance with the New Zealand Guide to Temporary Traffic Management (NZGTTM) is mandatory, and failing to secure approval from the Road Controlling Authority (RCA) can result in penalties or project shutdowns. A TMP outlines clear strategies for minimising disruptions, directing traffic efficiently, and reducing liability in case of incidents.

A well-designed TMP improves project execution by identifying risks, implementing control measures, and maintaining operational efficiency. Traffic congestion and confusion decrease when road users receive clear guidance on detours, speed limits, and restricted areas. Proper planning ensures emergency vehicles, pedestrians, and cyclists navigate work zones safely.

Approved TMPs help organisations streamline processes, avoid compliance issues, and maintain public confidence in their ability to manage road disruptions effectively.
