Fall arrest systems and anchors points are not building maintenance units therefore they are not SS10.
The rationale...
The original 1991 Building Act provisions covered life safety equipment, mechanical or electrical in nature. Fall arrest systems are not.
The NZ Building Code Handbook also provides advice
SS10 says this
A building maintenance unit is required to be
listed on a compliance schedule where the unit:
A.1 provides access to exterior or interior walls
of a building, and
A.2 is installed as part of the building, and
A.3 is mechanical, electrical, or hydraulic in nature.
