NZTA Investment Monitoring - Overview



Public funding provides for nearly all land transport services and infrastructure in New Zealand – and we’re accountable to New Zealanders for how we invest in that funding. This means closely monitoring costs and showing that services and infrastructure we’ve invested in fulfil their intended purpose and deliver their expected outcomes and benefits.


This section of the P&I Knowledge Base provides information about the different activities of NZTA Planning & Investment’s investment monitoring framework.


Annual Achievement Reports

Each Approved Organisation and NZTA (state highways) must provide an annual achievement report to the NZTA.


NZTA is accountable for its investment decisions. The information provided in the achievement reports provides feedback on the delivery of the programmes that NZTA has purchased. The achievement reports are also used for benchmarking Benchmarking is undertaken when the NZTA makes comparisons against similar regions and the national average. A lack of information supporting differences from regional and national averages may result in changes to the efficiency rating for public transport or maintenance programme or a requirement for a study as a condition of investment approval. Trends in these measures over time are used rather than just annual values. and comparing network performance across New Zealand. Reports are developed by NZTA using the information provided, and are made available to Approved Organisations and NZTA (state highways) for their use.


The report must be submitted to the NZTA via Transport Investment Online by mid-July.  The precise date is defined each year in a General Circular issued by NZTA.



Investment assurance activities

The investment assurance framework focuses on providing assurance about the services and infrastructure NZTA invests in. It also seeks to systematically identify opportunities to improve both NZTA’s and the transport sector’s performance.


The framework covers three main audit and monitoring activities:

The table below summarises the focus and scope of these different monitoring activities, the assurance they seek to provide, and business improvement opportunities they aim to identify.
