Road Controlling Authorities (RCAs) across New Zealand, including Auckland Transport, are in the process of adopting the NZ Guide to Temporary Traffic Management (NZGTTM) published in April 2023. The guide replaces the Code of Practice to Temporary Traffic Management (CoPTTM).
The transition is to a risk-based approach that aims to ensure temporary traffic management (TTM) setups are as safe as possible for the specific risks at each site.
In July 2025 AT notified the industry that we will be transitioning to NZGTTM and assessing all new applications using the NZGTTM from 1 July 2026.
Programme Structure
The TTM Transformation Programme is a series of initiatives designed to support Auckland Transport's and the industry’s shift to risk based TTM. The changes aim to improve safety outcomes, optimise costs and minimise disruptions around worksites.
It is made up of two key focus areas:
- Industry Transition: AT is playing a leadership role in the industry transition to risk-based TTM. 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. We are now in the facilitate the transition phase.
- Enabling AT: focuses on delivering and improving internal capabilities, ways of working 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 collective effort that involves implementing innovative steps while continuously engaging with the industry, experts, and stakeholders.
Phase One - Initiate the transition
There are over 1,500 TTMPs active on any given weekday in Auckland, and the number of requests to access the road network continues to grow. We want to facilitate this growth while minimising disruption and cost (where possible), without compromising on safety.
From September 2023 as part of project initiation, we developed a new corridor application assessment process framework and completed consultation with leading industry partners. This work has delivered new processes and tools that are already making a difference, for example -
NZ Forward Works Viewer - Transport Disruptions Assessment
To allow contractors to self-assess the impact of a proposed worksite on the transport network and give AT the ability to identify highly disruptive works, we have developed a Transport Disruption Assessment tool. This tool is now incorporated into an interactive map on the NZ Forward Works Viewer.
The tool was successfully tested with contractors Fulton Hogan, Downer, and Liveable Street and was activated for the whole region in July 2025.
Network Access Coordination Forum (NAC)
To balance the disruption, cost, and risk involved in approving proposals for necessary road works, the NAC forum was launched. It reviews potentially disruptive projects identified through the NZ Forward Works Viewer and brings subject matter experts from operational teams together to authorise final temporary traffic management decisions.
In Warkworth during recent Watercare works, this strong partnership and early proactive planning helped significantly reduce disruption to residents, businesses, and traffic.
Phase Two - Facilitate the transition
Since early 2024 we have made significant strides towards reshaping how TTTM is delivered across the region, focusing on improving safety, reducing disruption, and supporting industry through change. Here are some initiatives we are working on -
Smarter disruption planning
To help with early identification of potentially disruptive projects and coordinate opportunities between multiple planned projects our planning tool Forward Works Viewer has been upgraded.
This is helping to reduce inconvenience for businesses and residents, minimise impact at high-traffic times and shortened the duration of disruptive works.
Disruptions during peak times
To support more reliable journey times Auckland’s busiest roads are now reserved for travelling Aucklanders during the busiest hours of the day. Lane closures during peak hours (7am-10 and 4pm-7pm on weekdays) are no longer approved, except where it is unsafe or more disruptive to prevent lane closure.
To keep customers informed all work sites must have signage explaining the works, who is doing the works and their duration.
Redundant TTM Equipment Clean-Up
To help clear the way for Aucklanders, improve road safety, and enhance the overall experience for all road users, a sweep of the urban network to remove redundant TTM equipment was completed in late October 2025.
This has resulted in the collection of over 15,000 pieces of unused equipment! Clearing unnecessary or unauthorised equipment helps maintain a safe and compliant network
The programme will continue, with a second sweep of the network planned. It is expected to start at the end of December 2025 and run through to April 2026.
Light Touch Audits on arterials
We want Aucklanders to have safe journeys through well-managed work zones, with fewer delays and disruptions leading to greater confidence in how roadworks are delivered.
To ensure TTM setups are safe, compliant, and minimise disruption for road users we are carrying out light-touch audits across all key arterial routes.
The audits aim to identify and resolve issues before they impact the public and we’ll complete 150 per month for the remainder of 2025.
What’s next?
Starting late October 2025, we will present a series of four industry and public online webinars. Feedback from the first webinar will help us develop content for subsequent webinars.
Date and time details and links to register will be published at the top of this page.

Risk Assessments: Better Together
Share Risk Assessments: Better Together on Facebook Share Risk Assessments: Better Together on Twitter Share Risk Assessments: Better Together on Linkedin Email Risk Assessments: Better Together linkThis article presents general observations from Auckland Transport’s Temporary Traffic Management (TTM) advisory team. It supports continuous improvement within the temporary traffic management industry and does not reference any specific individual or organisation.
As we move from the Code of Practice for Temporary Traffic Management (CoPTTM) to the New Zealand Guide to Temporary Traffic Management (NZGTTM), it is important to reflect on how different Persons Conducting a Business or Undertaking (PCBU) may naturally focus on certain risk categories. This tendency is influenced by factors such as resources, cost, time, reputation, and health and safety, all of which shape effective risk management strategies.
NZGTTM requires all parties to consider risks for all recipient groups, while CoPTTM provided broader, systemic coverage for three main parties/elements at risk: network functionality, road users, and workers. Individual perceptions of risk are shaped by past experiences, knowledge, focus, and other factors, which can lead to blind spots. Similarly, different PCBUs may prioritise certain risks over others, as observed in risk assessments and worksite TTM practices.
Common Risk Assessment Challenges
Many traffic management plans submitted as NZGTTM applications do not adequately consider risks before implementing controls. Assessments are often missing, incomplete, or do not clearly define net risk after controls. Sometimes, risks are only evaluated after mitigations are chosen, without addressing any transferred or residual risks. Changes may resolve one issue but create another, and there is often little insight into why specific controls and trade-offs were selected. Risk matrices frequently overlook details, such as steel plates present during certain phases and considerations for unattended states, especially regarding psychological impacts on road users. Excessive false alarms from unnecessary temporary speed limits or warnings can decrease compliance network-wide, undermining the effectiveness of safety installations where they are genuinely needed.
Importance of Comprehensive Planning
Effective planning, including thorough risk assessment and temporary traffic management mitigations, requires collaboration among project management, health and safety, construction planning, traffic engineering, and stakeholder engagement. This ensures outcomes that are safe, coordinated, and efficient.
Risk Focus Tendency Matrix
The following conceptual matrix, developed from aggregated observations, highlights typical focus areas for different elements assessing risk. It is designed to prompt reflection and discussion, not to serve as a definitive guide for any specific situation or PCBU group. Note that Auckland Transport's functions as RCA, Principal, and Advisory may not all be represented.
Dot = Primary focus area: Elements typically concentrate on safety, processes, cost, time, workflow planning, and impact intensity. These areas often reflect greater insight and knowledge.
Circle = Secondary focus area: Areas that receive less consideration, representing potential blind spots.
Why These Patterns Matter
This matrix demonstrates the necessity of a multi-party approach—the 3Cs: consult, cooperate, and coordinate. Each PCBU’s natural focus can create gaps that others must help address. For instance, a presentation at the 2024 Tarmac Conference illustrated how pedestrian exposure to overhead work zones varies. CoPTTM might call for closing a large section of footpath for the day, while NZGTTM could allow for a more tailored, moving closure that aligns with the location of overhead works. This reduces net risk by minimising site footprint and improving behavioural compliance and network satisfaction. A risk-based approach compels all PCBUs to consider all parties at risk, not just their usual areas of concern. This matrix is just one example for how different parties might have primary or secondary concerns and is for illustrative purposes.
Characteristics of Comprehensive Traffic Management Plans
Traffic management plans (TMPs) that demonstrate a more thorough risk consideration show that PCBUs actively work to identify and address areas needing more attention through:
- Full cross-functional risk consultation involving all PCBU parties (the 3Cs).
- Structured risk assessments that systematically address all three elements/parties at risk, developing solutions using the hierarchy of controls before determining the final approach, making these assessments actionable for those involved at relevant times.
- Measured, digestible risk matrices tailored to specific works, with practical applications for onsite parties and clear protocols for sharing risk information across PCBUs.
- Defined assurance and monitoring actions, roles, and responsibilities to track effectiveness across all risk areas, fostering mutual understanding of chosen approaches and setup rationale.
Auckland Transport’s Role as Road Controlling Authority (RCA)
As RCA, Auckland Transport reviews applications through a holistic lens, considering all risk holder categories and elements. Key evaluation principles have emerged as understanding of the risk-based approach has evolved. These principles reflect a commitment to worker and public safety and network integrity and are applied in line with national guidance and regulatory frameworks.
Towards Actionable Risk Assessments
Adopting ISO 31000 Risk Management Principles can guide improvement:
- Integration: Embed risk management in all organisational activities and decision-making.
- Structured and comprehensive: Take a systematic approach that addresses all types of risk. Note that risk registries are not risk assessments; avoid overloading assessments with too many items to maintain clarity.
- Customized: Tailor risk management frameworks to the organisation’s context and objectives.
- Inclusive: Involve relevant stakeholders to incorporate their knowledge and perspectives.
- Dynamic: Monitor and review risks continuously, recognising they change over time.
- Evidence-based: Base risk management on the best available information.
- Human and cultural factors: Acknowledge the significant influence of behaviour and culture on risk management effectiveness.
Moving Forward Together
Recognising natural focus areas—and where some risks may be overlooked—underscores the importance of collaboration. A risk-based approach encourages PCBUs to:
- Identify their own focus areas and potential blind spots.
- Consult with others to uncover overlooked risks.
- Coordinate systems for monitoring effectiveness across all parties.
- Communicate consistently and in a targeted way as risks evolve throughout a project.
As the transition continues, understanding will develop further, and many organisations are already making progress. By embracing the principles of consultation, cooperation, and coordination (the 3Cs)—in line with WorkSafe and the Health and Safety at Work Act—we can work towards meeting our duties and reveal risks critical to others.
With greater flexibility comes increased responsibility. This is how safer, more resilient outcomes can be created together.

Unnecessary and redundant Worksites – Q3 2025
Share Unnecessary and redundant Worksites – Q3 2025 on Facebook Share Unnecessary and redundant Worksites – Q3 2025 on Twitter Share Unnecessary and redundant Worksites – Q3 2025 on Linkedin Email Unnecessary and redundant Worksites – Q3 2025 linkThis section looks at how we’re working to make our roads safer and more efficient by tackling unnecessary or redundant worksites!
What does “redundant” mean?
- Redundant worksites are places where Temporary Traffic Management (TTM) is set up, but there’s no risk present. This can cause frustration for road users and lead to inefficiencies.
- On the flip side, there are also unprotected risk sites—places where there’s a risk, but no TTM has been put in place. Both situations are important to address for safety and public trust.
Proactive Redundant TTM Collection Update
Directionz Ltd launched its proactive collection of redundant TTM equipment across Auckland in late March. The company is gradually surveying the Auckland network to identify and retrieve obsolete TTM gear. This project is designed to improve both the efficiency and cleanliness of the network. Industry partners are encouraged to stay engaged, support this initiative, and respond when asked to remove designated items from their storage facilities.
As of 21st October 2025, a total of 15,046 items have been cleared from the network, while 5,477 exceptions have been noted and left in place. Further updates will be shared in the next newsletter.
Image 1 shows the amount of redundant equipment collected by Ward.
Image 2 shows the amount of equipment left in place, by Ward. How did we do this quarter?
Here’s a summary of TTM site inspection data for the Auckland Transport road network, including both redundant worksites and unprotected risk sites. The data aligns with Road Efficiency Group Te Ringa Maimoa’s (REG) reporting requirements.:
