New Zealand experience with implementation of the ESO-ESMO consensus guidelines for advanced breast cancer-report of achievements and lessons learned

•Advanced breast cancer (ABC) care in New Zealand is applied inconsistently across patients. It often fails to meet international standards.•ABC care could benefit from creation and implementation of NZ-specific guidelines.•ABC5 guidelines were adapted to fit NZ context and some new NZ-specific guidelines were created. These were voted on by a multidisciplinary panel, leading to 115 guidelines for ABC care in New Zealand.•We report our experience with the process and plans to implement the guidelines and assess their uptake and efficacy.
