NZ Transport Agency Launches Investigation into Breath Test Scandal

The New Zealand Transport Agency (NZTA) has initiated an independent investigation into irregularities in alcohol breath testing data, following revelations that approximately 30,000 tests may have been inaccurately recorded. Reports indicate that around 130 Police staff nationwide are currently under scrutiny for their involvement in this scandal.

In response to the ongoing investigation, NZTA has suspended $6 million in funding to the Police. Funding will remain on hold until NZTA is assured that the Police have met their breath test targets. Details of this situation have emerged from a series of reports obtained by Radio New Zealand (RNZ) under the Official Information Act.

Independent Analysis Underway

According to a report dated October 27, 2023, NZTA has selected a preferred supplier to conduct an independent analysis of the breath testing data provided by Police. This analysis aims to determine if any further irregularities exist beyond those already identified by the Police. The initial investigation centers on an algorithm that suggests a second breath test was conducted within 90 seconds of the first, with a recorded speed exceeding 20 km/h between tests.

In an earlier update on October 13, NZTA stated that the Police had not yet been able to ascertain whether any irregular testing occurred while officers were stationary. NZTA is actively encouraging the Police to explore options for overcoming these limitations and to investigate further detection methods to accurately assess the full scope of the irregularities.

Transport Minister Chris Bishop expressed his concern over the matter, emphasizing the importance of resolving the issue swiftly. He stated, “NZTA have kept me regularly updated as the work has progressed. Independent analysis is underway, and NZTA are working closely with Police. NZTA will have more to say early next year.”

Funding and Future Steps

NZTA has requested assurances from the Police regarding the accuracy of delivery numbers for breath screening tests and other road policing measures for the 2024/25 financial year and the first quarter of the 2025/26 financial year. The independent analysis is expected to be completed early next year, with final results verified by early 2026.

In a statement, Johnson, a representative from NZTA, confirmed that funding for road policing activities had been paused while the Police investigation is ongoing. “Police is working closely with our NZTA partners to resolve this matter as quickly as possible. We acknowledge it is important the data being assessed is accurate and the activity being carried out is legitimate,” Johnson said.

Despite the ongoing investigation, Police continue to maintain a high level of breath testing activity, with plans for increased visibility during the summer months. Johnson reiterated, “We will continue to have a high-visibility presence over the summer period.”

The outcome of this investigation could have significant implications for New Zealand’s road safety measures, highlighting the critical need for transparency and accuracy in law enforcement practices. As the independent analysis progresses, both NZTA and the Police are under pressure to restore public trust in their breath testing protocols.
