Court record, proven alcohol and drug use
In January 2020 she led police on a high-speed chase across Auckland, reaching about 175 to 180 km/h over the Harbour Bridge. The High Court judgment proves alcohol and Class B drug (MDMA) use: blood alcohol over twice the legal limit, MDMA present in the same sample, and guilty pleas to causing injury while under the influence of drink and/or a drug. Two passengers were seriously injured. She was convicted and later failed in an appeal to discharge the conviction for career and travel reasons, including cybersecurity employment concerns.
