Elements in this unit standard are in a marine context. Abrasives and equipment
selection, coating systems and settings may differ from non marine applications
because of: extreme application and operational environments which are often
subject to salt and corrosion; time constrained dry dock or slipping considerations;
unique work techniques used for ship and boats because of the vessel’s shape and
accessibility; unique work techniques necessary due to specially formulated marine
paint systems.

Please note
Providers must be accredited by NZQA, or an inter-institutional body with delegated
authority for quality assurance, before they can report credits from assessment against
unit standards or deliver courses of study leading to that assessment.
Industry Training Organisations must be accredited by NZQA before they can register
credits from assessment against unit standards.
Accredited providers and Industry Training Organisations assessing against unit standards
must engage with the moderation system that applies to those standards.
Accreditation requirements and an outline of the moderation system that applies to this
standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The
AMAP also includes useful information about special requirements for organisations
wishing to develop education and training programmes, such as minimum qualifications for
tutors and assessors, and special resource requirements.
