In Aotearoa New Zealand, almost 2,500 people are treated for cardiac arrest each year. Alongside the community, ambulance services have a strong influence on survival. The Out-of-Hospital Cardiac Arrest (OHCA) Registry Reports are annual scientific reports benchmarking us internationally on resuscitation performance, from community response to advanced life support.

Each year we release three reports: one for Hato Hone St John, one in conjunction with Wellington Free Ambulance, and one for all New Zealand.
