Next they were called to a car crash, with four people trapped in the wreckage and lots of fake blood. They used the jaws of life to cut up the car, then carefully extricated the patients. Others tackled a fire in a giant stack of pallets, simulating a collapsed building.
Sixteen-year-old Raiha Kopa, from Moerewa, said the day had taught her about teamwork, communication and adapting to new situations.
Her favourite part had been the search for the missing pilot and learning to communicate with the Search and Rescue base by radio. The pilot's confusion, caused by head injuries, had been compounded by munching on mushrooms he'd found in the forest.
"It was awesome. It was cool to find him," she said, adding that she was now considering volunteering with the Kawakawa Fire Brigade.
The aim of the scheme, funded by the Ministry of Youth Development and trialled last year in Kaikohe, is to get young people more involved in their communities and encourage them to volunteer.
Among the emergency services personnel taking part on Saturday was 18-year-old Parehuia Tito-Paraone, who started as a YES trainee last year and is now a member of the Kaikohe Fire Brigade.
"It's really satisfying to know you can do stuff like this and help people who need it. I'd recommend it 100,000 per cent," she said.
The participants were nominated by schools, iwi and social services.
They will graduate at a formal dinner in Kawakawa on June 20, and will be invited to volunteer for two months with the emergency service of their choice.
