Business Case Approach to project development

NZTA uses the Business Case Approach (BCA) as the basis for activity and programme development for investment through the National Land Transport Programme (NLTP). In 2023 we refreshed our BCA guidance to ensure it's up-to-date and to provide more information about the five-case model as well as the business case phases.

Business Case Approach guidance

We’ve consolidated information for NZTA projects with guidance for all BCA users. Technical requirements for NZTA can now be found on our references and standards page.

Project delivery

Project delivery may be described as the process by which the aim or goal of a project is realised or achieved. The term 'project delivery' encompasses more than just 'project management' and includes all of the steps required to facilitate completion of the project, bringing the project to life from pre-implementation (initial design development, consenting and property) through to implementation (final design and construction) and handover of the asset for operation.
