AI to be used in reading breast cancer scans from next year
Health Minister Simeon Brown confirmed that artificial intelligence will serve as a secondary review for breast cancer screenings in New Zealand, with implementation planned for early 2027. The initiative, part of a broader effort to enhance early detection, follows a procurement process that evaluated market options, with a tender closing on March 4. AI tools would analyze mammograms to identify tumors, flagging unclear cases for additional scans, while emphasizing that the technology would “support, not replace” radiologists.
The national BreastScreen Aotearoa program currently screens approximately 270,000 women annually, with a phased expansion to include those up to age 74. Minister Brown highlighted that breast cancer is the most common cancer diagnosis among New Zealand women, noting that early detection improves survival rates. He emphasized that patient data privacy remains a priority during the procurement process, with input from patient advocates and the Breast Cancer Foundation shaping discussions on data access and security.
Health New Zealand will collaborate with clinicians and radiologists to test and validate the selected AI tool before its rollout. While exact costs remain unspecified, the government aims to integrate AI into every mammogram to streamline diagnoses and reduce wait times. Brown described the move as a step toward modernizing breast screening, ensuring more cancers are detected at treatable stages.
Did You Know? The AI tool will function as the second independent read in the mammogram assessment process, a standard practise currently used to improve diagnostic accuracy.
Expert Insight: Integrating AI into medical diagnostics requires balancing technological efficiency with human oversight. While AI can enhance speed and consistency, its success hinges on rigorous training and maintaining clinician involvement to address complex cases and build public trust.

The government has not specified which AI vendor will be selected, nor has it outlined timelines for full implementation beyond the 2027 target. However, the focus remains on leveraging technology to complement existing healthcare workflows rather than disrupt them.
Frequently Asked Questions
- When will AI be used for breast cancer screenings in New Zealand?
- Planned implementation is set for early 2027, following the completion of the procurement process.
- How does the AI tool function in mammogram analysis?
- The tool assesses mammograms for tumors using historical data, identifying whether a tumor is present, absent, or requires a second scan for clarification.
- Will AI replace radiologists in breast cancer screenings?
- No, officials have stated AI will “support, not replace” radiologists, with final diagnostic decisions remaining in the hands of qualified health professionals.
