The Investment decision-making framework (IDMF) provides a structured and logical approach to how investment decisions are made. The core elements are:
This diagram illustrates the end-to-end transport planning and investment system and where IDMF fits within this system.
The diagram shows how the strategic and planning drivers feed into the development of Regional Land Transport Plans and the National Land Transport Programme.
In 2019, Waka Kotahi NZ Transport Agency undertook a review of the IDMF, including how investments are developed, assessed and prioritised for funding.
Waka Kotahi and the Ministry of Transport worked together to revise the IDMF, with support from Local Government New Zealand (LGNZ). We also worked with other local government and local authority representatives, as well as Treasury, to get their input into the investigation, design and delivery stages of the review.
The review was prompted by changes in the Government Policy Statement on Land Transport 2018 (GPS), which placed more emphasis on social, economic, cultural and environmental outcomes in transport planning.
GPS 2018 also required an investigation of the Waka Kotahi evaluation methods, and this was incorporated as a core part of the review.
The review took into account the principles outlined in GPS 2018; that all modes of transport, land use, technology, and innovation are considered and valued in transport investment. We also sought to improve the business case approach to making the case for investment.
The IDMF review took place throughout 2019 and was implemented in June 2020, in time for the development of the National Land Transport Programme (NLTP) 2021–24.
Implementation included updated investment policies, processes, tools, and guidance (including updates to the business case approach, criteria for prioritisation and assessment, and evaluation methodologies).
