New Zealand Guide to Temporary Traffic Management (NZGTTM) soft launch

From 4 May 2026, Auckland Transport will begin a soft launch of the NZGTTM guidelines, with all Corridor Access Requests (CARs) assessed using this approach.

This soft-launch period is intended to:

  • help industry test the NZGTTM process
  • build capability and confidence ahead of full transition
  • identify and resolve issues before NZGTTM becomes mandatory for new CARs. 

Industry is strongly encouraged to use this period to prepare for the full transition on 1 July 2026.  

What the TTM Transformation Programme is

The Temporary Traffic Management (TTM) Transformation Programme is our programme to support the move to a risk-based approach to managing road user safety and traffic across Auckland's road network.  

The programme focuses on:

  • developing new ways to collaborate to deliver safer outcomes at worksites on the road corridor
  • implementing improved processes to manage network disruption
  • creating updated reference materials for the industry
  • providing education to raise awareness through a series of industry webinars. 

It brings together changes to how TTM is planned and assessed, alongside guidance, tools and engagement to support the transition.  

What’s changing  

We’re moving to a risk-based approach to temporary traffic management, in line with the New Zealand Guide to Temporary Traffic Management (NZGTTM).  

This replaces the old, prescriptive Code of Practice for Temporary Traffic Management (CoPTTM).  

Risk-based TTM means work sites are designed and managed based on the actual risks at each location - keeping road workers and road users safe, while avoiding unnecessary cones, delays and disruption.  

Why this matters  

Works on the road or footpath are essential, but poorly planned traffic management can create unnecessary congestion, cost and frustration. At the same time, people continue to be seriously injured or killed at road work sites.  

The TTM Transformation Programme aims to:

  • improve safety at work sites and on the road corridor
  • reduce disruption and delay on the road network
  • support more efficient, cost-effective traffic management.

Our role as Road Controlling Authority

As Auckland’s Road Controlling Authority, we:

  • approve access to the road corridor
  • coordinate road works across the network
  • review and audit work sites.

We do not prescribe specific traffic management methods. Responsibility for identifying and managing risk at each site sits with the organisations carrying out the work, in line with health and safety law.  

How we’re supporting the transition  

We’re working with industry to embed safer, smarter ways of working, including:

  • improved planning and coordination of road works
  • restrictions on lane closures during peak travel times
  • clearer on-site signage for the public
  • removal of redundant and unused traffic management equipment
  • targeted audits on key arterial routes
  • online webinars and guidance to support the transition.

Key dates for NZGTTM

From 4 May 2026 - soft launch

We will begin to process CARs using the NZGTTM approach. Applicants will need to include a risk assessment or risk control plan as well as all other documentation.

Industry can begin testing the NZGTTM process and building capability.

From 1 July 2026

All new CAR applications will be assessed using NZGTTM.

From 1 July 2027

All existing Traffic Management Plans (TMPs) will be transitioned and assessed using NZGTTM.

Guidance, resources and further information

We’ve brought together guidance, tools and supporting material to help industry understand and apply the NZGTTM approach.

Formal notices and updates

Industry should check this page regularly to stay up to date.  

What industry needs to do now

We recommend you use the NZGTTM soft-launch period to practise and strengthen risk assessment reporting.

Early preparation will support smoother CAR processing and safer, more efficient worksites as NZGTTM is phased in.

Stay informed

We’re committed to working collaboratively with industry and keeping Aucklanders informed as we move closer to full NZGTTM adoption.
