The Integrated Delivery Model (IDM) is the new contracting model for the majority of the road maintenance requirements across Aotearoa New Zealand. Waka Kotahi NZ Transport Agency has developed this model following the NOC Review that took place during 2022, and the IDM will replace the NOC model from 2026 onwards.

Our vision for the IDM is that those working in the road maintenance sector are empowered to bring their best selves to work every day, supported by an environment that links people together, inspires them, supports them and grows their skills to enable the delivery of great transport outcomes for Aotearoa.

The IDM will enable Waka Kotahi and the road maintenance sector to become more efficient and coordinated in the delivery of corridor-level improvements. At the heart of the new model is an aim to simplify commercial and delivery mechanisms to focus road maintenance requirements on outcomes that deliver value to New Zealanders.

We do however want to keep elements of the NOC model that have worked well. For example, our emergency response mechanism is considered world class, and we want to ensure that this is carried through into the IDM.

The IDM ensures Waka Kotahi gives effect to the State Highway Asset Management Plan (SHAMP), which shows how maintenance, operations, and improvements together provide services to customers. Maintaining and operating the existing state highway network ensures road users have safe and accessible roads to travel on.

Prior to 2026 we will be developing the new model and the contract form (the Integrated Delivery Contract) that will give life to our vision. As part of this we will be using Pilot contracts to test how various contract features function in a real live contracting environment. We are expecting to run the Pilots for 2-3 years, using the findings to inform the development of the IDM. We will purposefully engage with a wide range of industry representatives to share the learnings from the development and implementation of these Pilots.

All existing NOCs will continue until procurement takes place, with contract extensions enabled in line with our procurement plan for the IDM. This will ensure we have consistency of delivery now while we develop the right model for the future. The exact timing of the procurement for each new contract will be released in due course.

Pilots

We are currently aiming to have features ready to test under Pilot contracts by April 2024. The initial pilot contracts will be located in the lower South Island, covering the West Coast, Central Otago, Coastal Otago and Southland networks.

The current list of features being considered can be found in the following presentation, which was delivered at the Industry Liaison Meeting on Thursday 23 November.

Some of these features will be incorporated into the day-to-day operation of the Pilot contracts, whereas others, such as mid-term pricing review, will use the Pilot contracts as an opportunity to discuss how this could work in practice.

The outcomes of the Pilot and the feedback we receive will be fed into the development of the final contract model. We will provide this information to industry following the end of the Pilot period.

Communication

Throughout the development of the IDM we will keep external stakeholders and partners informed of our progress. Regular e-newsletters will be produced, and you can sign up to these directly via the subscribe link.
