Debt funding may be used by the Waka Kotahi NZ Transport Agency to provide additional financing to bring forward infrastructure expenditure or for liquidity reasons.
A public private partnership (PPP) is a procurement method that usually involves debt funding. It is a long-term contractual collaboration between the public and private sectors to procure transport infrastructure and services. It requires the construction or enhancement of an asset, which is financed, designed, built, operated and maintained by the private sector partner, until its transfer to the public sector at the end of the contract.
This section sets out the guidance on the Waka Kotahi current PPP model including when it should be used to procure projects and how value for money is determined.
The Waka Kotahi has borrowed funds from both public and private sources.
As a Crown Entity, the Waka Kotahi requires approval under section 160 of the Crown Entities Act(external link) from both the Minister of Transport and the Minister of Finance to use debt funding.
Waka Kotahi has borrowed funds from both public and private sources as follows:
PPPs will only be suitable for certain projects.
In general, this form of delivery model is suited for larger projects, with significant or complex operational or maintenance requirements, and where there is substantial scope for innovation.
PPPs will only be suitable for certain projects where:
Under the Waka Kotahi Procurement Manual, all PPPs are classified as customized procurement procedures (see section 2.8) and, as such, require approval under section 25 of the Land Transport Management Act.
Procurement processes are guided by legislation, guidance and PPP documents.

Although the structure of each PPP will be tailored to suit the context, the model adopted by Waka Kotahi involves a number of components.
Procurement processes are guided by:

Under Waka Kotahi policy on PPPs obtaining best value for money is the ultimate goal of the PPP approach and is the key measure of success.
PPP procurement may be considered as a procurement approach for state highway improvement projects where:
The value for money assessment will form part of a comprehensive business case, where the main problem to be addressed is identified and each potential procurement method assessed to determine the best solution. At this stage, the PPP is one option among many procurement methods.
In assessing value for money, Waka Kotahi is required to undertake quantitative and a qualitative analyses of procurement options, to consider the monetary and non-monetary costs and benefits of each option. In common with Waka Kotahi’s policy for evaluating the economic costs and benefits of projects, all future costs that have yet to be incurred must be included at each decision point.
CloseThe main test of best value for money is the comparison of a public sector comparator (PSC) to a proxy bid model (PBM).
The key aspects are:
The general idea is that if the value for money from the PPP is better than that of the next best procurement method, the PPP should proceed.
CloseThe bid process:
A bid will only be accepted by Waka Kotahi if it is the best value for money that Waka Kotahi can obtain.
