Procurement

We outsource the majority of works and services for our asset improvement and asset management projects. Our approach to procurement uses a range of delivery models. These models have been developed based on international best practice and adapted to the New Zealand context. With this selection of models we are able to:

• select the best model to deliver optimal value for money based on specific project and market characteristics
• develop strong, collaborative supplier relationships
• develop a strong skill base and understanding of the supplier market, including competitive rates, capabilities and commercial processes and
• avoid the potential for supplier manipulation of a single process.

The policies and processes fundamental to procurement within NZTA are detailed in the following documents:

• Procurement manual
• Infrastructure procurement strategy
• Contract procedures manual

Note: The Government Procurement Rules 5th edition (2025) was published by New Zealand Government Procurement (NZGP) on 9 October and comes into effect on 1 December 2025.  These changes impact how NZTA procures and manages contracts. We’ll soon be updating NZTA procurement documents to reflect the new Rules.

For more information on the 5th edition Rules see MBIE’s website.

Maintenance contracts

The maintenance and operations space has moved from the existing traditional, hybrid and performance specified maintenance contracts to a primary supplier model. This model brings professional services and physical works components into one contract, called the network outcomes contract.

Procurement activity is fundamental to the operation of the land transport system, delivery of the National Land Transport Programme (NLTP) and the operational enablement of NZTA. Many of the NZTA functions are performed, in full or part, using external suppliers.
