Death from cardiac arrest is the country's "silent toll".
About 1500 people die following a heart attack every year in New Zealand - a figure which is roughly four times higher than the national road toll.
St John Hawke's Bay territory manager Brendon Hutchinson said it is a statistic "everyone can change" and one which is slowly gaining momentum.
Today is International Restart a Heart Day (RAHD) and St John, in partnership with Wellington Free Ambulance, Fire and Emergency NZ and the NZ Resuscitation Council are joining together to teach everyone how to save a life.
