The New Zealand Transport Agency (NZTA) is currently conducting multiple internal investigations into alleged integrity breaches across several roading contracts, with its compliance and integrity team examining "approximately eight matters," the agency confirmed Tuesday. This marks an expansion beyond six previously reported contract probes, which were initially uncovered through investigative reporting earlier this year.
The investigations respond to allegations involving financial irregularities, procurement failures, and conflicts of interest tied to taxpayer-funded infrastructure projects. These issues came to light following reports highlighting more than NZ$5.1 million in unapproved or contested contract variations related to major road and motorway projects in Auckland and Taranaki.
Transport Minister Chris Bishop, responding to parliamentary questions from Green Party MP Julie Anne Genter, said NZTA has strengthened its financial controls after detecting "potentially fraudulent activity" on some contracts. He confirmed the ongoing inquiries relate to contract mismanagement, conflicts of interest, and financial discrepancies but declined to specify which projects are involved or the disputed sums, citing concerns that disclosure might hinder active investigations.
NZTA later clarified that the eight active cases encompass the six alliance contract investigations previously reported plus two additional integrity reviews. Alliances in this context refer to collaborative partnerships among government agencies, local councils, and private contractors managing significant infrastructure projects.
Among the investigations are a $602 million alliance established to rebuild roads and rail infrastructure following Cyclone Gabrielle, and the contractor alliance responsible for Auckland’s 200-kilometer motorway network. Other key projects under scrutiny include the $590 million Mt Messenger bypass and the $84 million Te Ara Tūtahu route improvements between Waitara and Bell Block. A preliminary review of the Cyclone Gabrielle alliance raised concerns over spending practices, accommodation arrangements for contractors, staffing levels, and resistance to transparency.
Julie Anne Genter criticized the agency, describing NZTA’s oversight as "extremely lax" in enforcing budget constraints for large roading projects. Bishop revealed that he was only informed of the investigations in May after questions from media outlets, expressing dissatisfaction with the speed and completeness of information provided by agency officials. That same week, Simon Bridges, chairperson of NZTA’s board, initiated an external review into the agency’s integrity processes.
Earlier in the year, NZTA had commissioned an independent review led by Wellington barrister Samantha Turner to assess and improve its procedures for handling protected disclosures and whistleblower complaints. Both this review and the external investigation were scheduled to report by June but have since been delayed until July, as additional time is needed to examine all pertinent information.
A spokesperson for NZTA said the extended timeline will allow comprehensive consideration of findings to ensure robust improvements to the agency’s integrity systems moving forward. Meanwhile, the Serious Fraud Office continues to investigate the financial conduct of the alliances involved in the audits.
