Temporary traffic management


Waka Kotahi is currently developing a new approach to how temporary traffic management will be delivered on Aotearoa New Zealand’s state highways and roads. The new guidance aligns with Worksafe’s Road Good Practice Guidelines (2022) and will be implemented from 2023 in stages to eventually replace CoPTTM. 

To learn more about the plans for this new approach visit the TTM Review page nzta.govt.nz/NZGTTM


Traffic management across New Zealand’s network of state highways and local roads is fundamental to keeping people safe on our roads. Our roads are used daily by vehicles, cyclists and pedestrians, and have many people working on them. Changes to the operation of these roads under temporary traffic management is a core activity on the network, providing safety and access to all road users and workers.

Waka Kotahi NZ Transport Agency (Waka Kotahi) is responsible for setting the requirements for the safe and efficient management and operation of temporary traffic management (TTM) on all roads in New Zealand. The Code of Practice for Temporary Traffic Management (CoPTTM) is best practice guideline for temporary traffic management in New Zealand.

The CoPTTM website is a comprehensive central hub that provides information relating to the application of the CoPTTM.

If you would like to know more about Waka Kotahi and what we are involved in, information is available through our Waka Kotahi website.
