About our major project reports

NZTA develops ‘major project’ reports to keep the public and stakeholders up to date about large capital projects we are managing on behalf of government and taxpayers. These reports help us to share information reliably and consistently. They are developed in line with the NZTA guidance on major projects.

Information about a project evolves and changes throughout the process of design and delivery. NZTA takes a robust and deliberate approach to understanding the problem that needs to be solved and what options there are for solving it. As we get better information, we can have more confidence about what the project will involve, how much it will cost, and its benefits.

Information gathered through processes to plan, design and deliver the project supports decisions about the project’s scope, how it will be paid for, and when and how it will be delivered.

We aim to communicate the right information at the right time so that:

  • everyone can understand decisions to date and what information they were based on
  • stakeholders can plan for impacts that a project will have on them over time
  • Ministers can have confidence that NZTA is investing public funds effectively and efficiently
  • we can minimise legal risk 
  • we can reduce pressure on our delivery teams 
  • we can avoid cost escalations 
  • we can stay open to better ways of solving the problem before us, thereby reducing costs and optimising benefits for taxpayers.
