"Time can be of the essence, especially in situations like heart attack, stroke or massive bleed."
Courses, which include subjects such as CPR and choking, are for all age groups and can range upwards from four hours.
A workplace compliance course that runs for 12 hours was popular, Lugo said, and was a minimum requirement for high-risk worksites as it covered the essentials then more advanced topics.
Those who have already done first-aid courses could sign up for a revalidation course to refresh their skills.
The courses will be run monthly, with the first on October 14 at Tararua REAP.
