Post Implementation Review (PIR)

The Post Implementation Review (PIR) is a review of benefits and costs that is conducted on a sample of large (> $500,000) construction projects after completion. The review compares planned benefits and costs with those actually delivered through the design and implementation processes.

This review is very useful to Approved Organisations and the NZ Transport Agency since it provides feedback on the integration and overall effectiveness of planning, design and implementation of large projects.

Currently 25 to 30 PIRs are carried out each year, with a 50:50 split between State highway and local authority projects.

Procedural audits

Road infrastructure safety assessment (RISA)

The Road Infrastructure Safety Assessment (RISA) programme is a safety- focused technical review of several sample sections of a road network, to identify areas that could be improved.

The RISA is based on international best practice guidelines. The audit is carried out in advance of a Technical Review and the results are included in the technical review report. The recommendations are typically used to prioritise safety improvements, which Councils can then include in their next Land Transport Programme.

Technical reviews

Road networks that are funded through the NLTP, are subject to periodic technical reviews of the assets.

Theme audits

Theme Audits each address a specific topic that is common to / affects many approved organisations. The topics may vary considerably. The choice of topic is made by limited survey involving NZTA auditors as well as representatives from approved organizations.

Between 1 and 4 theme audits are carried out each year. The results are published in individual theme audit reports for the purposes of:

  • informing approved organisations about issues that have been encountered, current good practice and future direction
  • feeding into policy development by the NZ Transport Agency or others in the sector such as Ministry of Transport, Local Government NZ, or the RCA Forum.
