Draft Investment Assessment Framework 2018-21 NLTP

The draft Investment Assessment Framework (IAF) [PDF, 554 KB] for the 2018-21 National Land Transport Programme (NLTP) has now closed.

Thanks to those who shared their thoughts and suggestions with us. Your feedback will be considered as we finalise the IAF, which will remain in draft until the Minister of Transport releases the final Government Policy Statement on land transport (GPS) (external link) by 30 June. We will notify you of any changes made to the draft IAF at this time.

A summary of the feedback we received will available on this webpage by 31 May.

The IAF is the framework the Transport Agency uses to assess and prioritise our investment partners’ projects and programmes for inclusion in the NLTP. It helps you to understand how your projects will be prioritised under the draft GPS and to frame-up Regional Land Transport Plans (RLTPs). 

The Transport Agency has reviewed and updated the draft IAF to reflect the new priorities the Government identified in the draft GPS of safety and access, environment and value for money.
