From Application to Approval: How the TMP Consent Process Works in New Zealand
Introduction
Getting a Traffic Management Plan approved can feel mysterious if you have never been through the process before. Who are you submitting to? What are they looking for? What happens if they send it back? This step-by-step guide walks you through the full consent journey.
Step 1: Determine Your RCA
The first step is identifying your Roads Controlling Authority (RCA). In New Zealand, RCAs are the organisations legally responsible for the road you are working on. Local councils control their own road networks, while Waka Kotahi NZ Transport Agency controls state highways. If your project crosses both a local road and a state highway, you may need approval from both.
Confusing the wrong RCA — submitting a WCC application to HCC, for example — is one of the most common causes of early delays. Traffic Management Aotearoa verifies the correct RCA for every project before submission.
Step 2: Prepare the TMP
Your TMP must comply with the TTM standard your RCA currently requires — either CoPTTM (the outgoing standard) or the NZGTTM (the new standard, which is increasingly being mandated). New Zealand is in a transition period: Waka Kotahi stopped updating CoPTTM in November 2024, and many councils are moving to require NZGTTM-compliant plans, with several setting a hard deadline of 1 July 2026. Always check with your RCA before preparing your plan.
Under both standards, the TMP must be prepared by a suitably qualified person. The core content is similar: a description of the works, road characteristics and traffic data, Traffic Management Diagrams, site establishment and removal methodology, contingency plans, and contact details for all key parties.
Step 3: Submit and Track
Most RCAs now accept TMP submissions through an online portal or by email. The submission must include the completed TMP form, all attached TMDs, and any supporting documents such as a Works Access Permit (WAP) application, Metlink approvals, or parking restriction authorisations. Most portals now ask you to declare whether your TMP was prepared under CoPTTM or NZGTTM — be accurate, as this affects how the RCA reviews it.
Once submitted, the RCA’s Traffic Management Coordinator reviews the plan against the applicable standard and their own local conditions. Review timeframes vary — Wellington City Council typically targets 10 working days for complex Full TMPs, while some smaller councils can turn around straightforward plans in 2-3 days.
Step 4: Manage Revisions
It is common — especially for complex projects — to receive a request for revisions. The TMC may ask for additional signing, clearer pedestrian diversions, additional dates, or revisions to reflect local conditions they know from experience. Responding to these quickly and completely is critical to keeping your programme on track.
Traffic Management Aotearoa includes revision management as a standard part of our service — we track every comment from the TMC and ensure our response addresses each point before resubmission.
Step 5: Notify and Start
Once the TMP is approved, the RCA issues a CAR (Corridor Access Request) reference or WAP approval. Before starting work, the person responsible for TTM must notify the TMC as specified in the approved plan, and residents and businesses must receive the required advance notice — typically five working days before road closures begin.
From the moment work starts, the approved TMP must be on-site at all times and must reflect actual conditions. Any significant changes must be reported to the TMC promptly.
