Public Private Partnerships

The New Zealand Public Private Partnership (PPP) Programme is coordinated by the Infrastructure Transactions Unit (ITU).

This section of the Treasury’s website contains information about the New Zealand PPP Programme and the Standard Form PPP Project Agreement.  Updated PPP guidance material and project information will be published on this website from time to time.

Public Private Partnerships

In the New Zealand context, a Public Private Partnership (PPP) is:

a long term contract for the delivery of a service, where the provision of the service requires the construction of a new asset, or the enhancement of an existing asset, that is financed from external (private) sources on a non-recourse basis and where full legal ownership of the asset is retained by the Crown. 

The primary purpose of PPP procurement is to improve the delivery of service outcomes from major public infrastructure assets by:

  • integrating asset and service design
  • incentivising whole of life design and asset management
  • allocating risks to the parties who are best able to manage them, and
  • only paying for services that meet pre-agreed performance standards.

The Infrastructure Transactions Unit

The ITU has been established to support agencies and local authorities to procure and deliver major infrastructure projects. As part of this role the ITU is responsible for:

  • developing PPP policy and processes
  • assisting agencies with PPP procurement
  • the Standard Form PPP Project Agreement
  • engaging with potential private sector participants, and
  • monitoring the implementation of PPP projects.

The ITU can be contacted by email at
