Temporary Traffic Management Transformation Programme
Transforming the way we do temporary traffic management to support Tāmaki Makaurau's future
The Temporary Traffic Management (TTM) Transformation Programme is a series of initiatives aimed to improve safety, optimise costs and minimise disruptions around worksites. The core strategy of the programme is to roll out and support Auckland Transport's and the industry’s change to risk based TTM.
Programme Structure
The Programme is made up of two key workstreams:
- Industry Transition: AT is playing a leadership role in the industry transition to risk-based TTM. We expect this to be at multi-year process. All relevant organisations need to understand their obligations under the risk-based approach, changing roles of others in the ecosystem, the skillset required, and the operating systems required. This transition has three phases – initiate the transition, facilitate the transition, and sustain the new way.
- Enabling AT: This workstream focuses on delivering and improving capabilities and systems that enable Auckland Transport to:
- better influence how TTM is set up and managed at individual worksites
- better understand and manage the impacts of roadworks both at a local and regional level
- better fulfil its obligations as a major PCBU in Auckland
Our way forward is a joint effort that involves implementing innovative steps while continuously engaging with the industry, experts, and stakeholders.

Over the coming months, the TTM Transformation Programme will reaching out to the industry to seek input on how AT should be rolling out the change to a risk-based approach.

There are over 1,500 Temporary Traffic Management Plans (TTMP) active on any given weekday in Auckland. The city is experiencing rapid growth in urban development and infrastructure upgrades which means projects, developers and utility providers require more frequent and more significant access to road corridors.
Auckland Transport aims to support this growth by enabling such access. However, finding the balance is not always achieved, there are concerns that the excessively cautious safety measures around roadwork sites are not effective resulting in a negative customer experience in various travel modes across the region. With the new risk-based approach, the New Zealand Guide to Temporary Traffic Management (NZGTTM) replacing the Code of Practice for Temporary Traffic Management (CoPTTM) allows the industry to deliver a better approach to the design and implementation of Traffic Management on our network. The key change is a move away from a prescriptive set of rules to a more flexible set of guidelines that emphasises planning for and managing risks.
As part of the TTM Transformation programme, we have developed an initiative that aims to give the Road Controlling Authority (RCA) the power to assess and evaluate corridor access requests (CARs) and influence the site-specific TTM plans. The primary objective is to minimise the disruption and cost (where possible) over worksites that have a high potential for network disruption, without compromising on safety.
The ‘Enhanced CAR Application Reviews’ has clearly defined objectives:
- Meaningfully challenge the corridor access request application.
- Surface the science in the process and remove individual risk bias.
- Make the process transparent to develop stakeholder trust in the outcomes.
- Balance Cost, Disruption, and Risk whilst preparing and assessing TMP proposals.
- Empower the contractors and contracting PCBU (Person Conducting Business or undertaking) to be able to put their best foot forward when applying for corridor access requests.
- Back our SMEs (Subject Matter Experts) when difficult decisions need to be made based on supporting evidence.
A lot of progress has been made since the project started in September 2023. We have outlined and are trialing the new corridor application assessment process framework and have completed consultation with leading industry partners.
Disruptions Assessment Tool (DAT +)
We have developed an assessment tool that enables the contractors to self-assess the impact of a proposed work site and give AT the ability to identify highly disruptive worksites. A pilot to prove the concept was launched in mid-December. Three pilot contractors, Fulton Hogan, Downer, and Liveable Street are taking part in the pilot.
Network Access Coordination Forum (NAC)
The Interim Network Access Coordination (NAC) forum has been launched, and its objective is to review potentially disruptive projects (identified through DAT+) on the network and provide balanced approvals. This forum brings subject matter experts (SMEs) from all the operational teams together with a chair who has the authority to make the final call.
All in all, we are looking in very good shape to be able to bring about much-needed clarity in the process and hopefully a reprieve in the TMP cost and disruptions. With this work completed, we will be in a very good position to switch our corridor access processes based on the NZ Guide to Temporary Traffic Management (NZGTTM) which has been released by NZTA Waka Kotahi to replace CoPTTM.

In September 2023, AT organised a co-design workshop with TTM Industry members to facilitate the transition to risk-based TTM. The workshop aimed to create awareness and draw out considerations by conducting a discovery workshop. During the workshop, the following objectives were reinforced:
- Reinforce the need to transition TTM in Auckland.
- Called on the industry to collaborate and engage with the change.
- Provide AT with insights into the opportunities and barriers that need to be accounted for as we plan our way forward.
After the workshop, attendees received a summary of the collective inputs and ideas raise

- Co-design a list of tasks or workstreams that are needed to transition to a risk-based approach.
- Share the progress made by each subgroup and journey so far.
- Determine who will lead the delivery of each task.
- Clarify the role of AT in facilitating or driving the process.

The TTM Transformation Programme team recently conducted knowledge sessions on NZGTTM at Customer Central. NZGTTM is a new guide to Temporary Traffic Management developed by Waka Kotahi that will replace CoPTTM in the next two years. This guide will replace CoPTTM's prescriptive set of rules with a more flexible set of guidelines that prioritizes planning and risk management. This is a significant change in the practice of TTM in New Zealand.
To ensure a smooth transition for AT, new systems and processes are being developed. The first step is to provide our teams with a solid understanding of NZGTTM. To achieve this, we partnered with Dave Tilton from Parallax to deliver insightful knowledge sessions. These sessions covered the rationale behind the transition from CoPTTM to NZGTTM, explored the differences between NZGTTM and CoPTTM, and discussed the changing landscape. During the workshop, teams learned about the contrast between a compliance-based TTM approach and a risk-based approach. The discussion allowed for a better understanding of how TTM might look in New Zealand over the next few years and the potential impact.
The sessions have been insightful and engaging, receiving great feedback. The TTM Transformation team will continue to engage with AT teams to develop other specialized knowledge sessions that will help AT transition to the risk-based approach.
