📋 Tender Overview
Following confirmation of preferred suppliers in late 2025, NZ Transport Agency Waka Kotahi (NZTA) and respective contractors have now formally signed Integrated Delivery Contracts (IDCs) for state highway maintenance and renewals.
The new contracted arrangements, taking effect from 1 May 2026, will see the selected contractors accountable for the majority of maintenance and renewal activity on the respective regional state highway networks.
NZTA National Manager Maintenance and Operations Andrew Clark says finalising the contracts is a significant step towards new ways of working for state highway maintenance.
The new arrangements set out in these contracts will drive improved road maintenance, benefitting everyone who uses our state highways. NZTA is focused on delivering long-term benefits through improved work programmes that deliver high quality work efficiently, minimising disruption for road users as much as possible.
Mr Clark says the Integrated Delivery Model for state highway maintenance (which the new contracts give effect to) brings together the separate elements of client, contractors and consultants, and is designed to reward delivery while enabling market diversification. Alongside the IDCs, up to 20% of work will be available to other pre-qualified suppliers through a separate contestable process.
This will support a more flexible approach that will be able to adjust as work programmes change over time based on future maintenance requirements.
NZTA is excited for the new contract model, and for the benefits to the travelling public who depend on a safe, accessible and high-quality state highway network.
