Waka Kotahi NZ Transport Agency and our investment partners use the Business Case Approach (BCA) to guide our planning, investment and project development processes. This section provides guidance on how the BCA works and what is required.
The Transport Agency collects transport data from investment partners as well as a range of government and non-government sources. This information, in the form of tables, reports and interactive tools, is useful to decision makers across the land transport sector.
The information and resources on this page help to explain the Transport Agency’s Investment Assessment Framework (IAF) for the 2018–21 National Land Transport Programme (NLTP) and our approach around making investment decisions.
