MediMap Hack: Patient Records Altered, System Offline – NZ Investigation

A digital medical records company, MediMap, has been taken offline following the modification of patient records, including instances where individuals were incorrectly marked as deceased.

Impact on Healthcare Providers

MediMap is utilized by healthcare providers in aged care, disability services, hospice care, and community health settings to accurately record medication dosages. The platform facilitates coordination between clinics, pharmacies, and patients, and supports e-prescribing alongside maintaining medication histories.

The company notified clinics that the issue began around 1:30 pm on Sunday and initiated a shutdown to investigate. As many as 60 percent of aged care facilities may use the app, forcing them to revert to paper-based processes.

Did You Know? The breach at MediMap occurred less than two months after a separate incident involving the patient portal Manage My Health, which experienced a data breach on December 30, 2025.

MediMap identified “unauthorised entry” involving names, dates of birth, prescribers, location of care, and resident status. The company is working with the Ministry of Health, specialist cyber experts, the Office of the Privacy Commissioner, and NZ Police.

MediMap director Geoffrey Sayer stated the company’s focus is on helping facilities continue patient care, followed by remediation and restoration. Sayer also apologized for the disruption and concern caused by the situation.

Government Response

Prime Minister Christopher Luxon described the breach as “concerning,” particularly in light of the recent Manage My Health incident, and advocated for stronger cybersecurity laws in New Zealand.

Associate Health Minister David Seymour emphasized the importance of cybersecurity, stating that New Zealand “cannot afford to be the weakest link” and that the government is actively working to improve its cybersecurity posture.

Expert Insight: The back-to-back breaches at MediMap and Manage My Health highlight the growing vulnerability of healthcare data in New Zealand. The reliance on digital systems for critical patient information necessitates robust cybersecurity measures and proactive investment in protective infrastructure.

The company is conducting “data integrity checks” and will provide guidance on resolving the issue and the timeframe for restoration.
