Life-saving training for flight nurses is under threat unless a sponsor can be found for mandatory helicopter training.
Nurses who fly with rescue helicopters in New Zealand are required to be trained in getting out of the machine underwater to be prepared if a craft ditches.
Diane Fuller, of the Flight Nurses Association, said funding was needed for the five-day national education course for flight nurses and aero-medical paramedics.
The not-for-profit organisation - a section of the Nurses Organisation - has started looking for a corporate sponsor so it can keep training.
The course provides crucial preparation for the specialised medical professionals and the training is mandatory. But the course is expensive and $10,000 extra funding is needed each year to train 24 nurses and paramedics.
