These are specialised technical skills; industry specific knowledge and skills, and specialised technology and equipment skills, which are unique to the relevant industry.
Examples would include:
Managing a dairy processing operation
Using agrichemicals in compliance with industry standards
These specialised skills are backed by years of experience, and typically there is a qualification on the NZQA framework to recognise the expertise level.
For example:
NZ Certificate in Diary Processing
NZ Certificate in Agrichemical Application
Progression within a specialised field, would involve gaining more skills and experience and continuing through the qualification pathway (i.e. Certificate, Diploma)
