Consultation is now open on the draft Investment Prioritisation Method (IPM) for the 2024-27 National Land Transport Programme (NLTP) and will close on 17 November 2023.

The draft IPM will replace the IPM for the 2021-24 period. It has been developed in response to the draft Government Policy Statement on Land Transport 2024 (released August 2023) and will be used to prioritise activities in the 2024-27 NLTP.

Next steps

At this stage, we expect to have a final IPM by mid-2024 after the Government publishes the final GPS 2024. This does mean some programmes and activities will have already been submitted based on the draft IPM.

We will ensure that all submissions are checked against the final IPM - both by the investment advisor, and through our moderation process.
