St John in Schools officially launched last year with a goal of reaching 12,000 tamariki (children) in that year, but exceeded expectations by reaching 17,500 with only four part-time educators.
St John community education team leader Andrea Webber said that this year's goal was 25,000 but are already on their way to reaching 32,000 tamariki with just five part-time staff.
"This programme is successful because of the quality of our educators. St John is known for its ambulances but we wanted to help communities at the children's level, to empower them with confidence in times of emergency, giving them baskets of knowledge so they know how to keep themselves safe until help arrives," she said.
