Every couple of months, on average, Craig Watts brings someone back to life. The intensive care paramedic has been in the business of saving lives for almost 35 years.
That's a lot of hearts kept beating because of the work of Watts and his St John Ambulance colleagues.
Barry Hegley's heart is one of them. The Howick great-grandfather went into cardiac arrest as Watts was driving him to Middlemore Hospital early on July 9.
Watts and his colleague, Neil Robins, brought the 84-year-old back to life while parked on the side of the road.
A mixture of 360 joules of electrical energy - twice - chest compressions, CPR, ventilation and sheer determination meant Hegley was able to recently return to thank his rescuers.
