If you are doing external plastering work as part of the construction or alternation of residential buildings, that work may be classified as “Restricted Building Work” (RBW). You must be a Licensed Building Practitioner in the External Plastering class to do or supervise this type of work.
A lot of residential building work will include External Plastering RBW, but if the work does not require a building consent then it is not classified as restricted.
See the guidance on What Restricted Building Work means for Brick and External Plasterers.
