"He does a bit of dancing, singing and interactive activities with the kids. He teaches them about the triggers of asthma - like dust mites, cold weather, viruses, emotions, animals and stress - and it's really engaging.
"The kids love the show and they're learning a lot as well."
The show is sometimes displayed at business conferences and is always well-received by adults too, Mrs Demetriou said.
Running costs and additional costs for the foundation to get out to various schools around the region means each show costs up to $300.
With the help of the grant, it can get to dozens more schools and therefore send its message to hundreds more New Zealand children.
Auckland Airport spokeswoman Anna Cassels-Brown said they were happy to help a group working to send out a necessary health message to youngsters.
"We are proud to support this brilliant educational initiative that teaches Kiwi kids about asthma and how to look after themselves and others."
