The NZ Metal Roof and Wall Cladding Code of Practice is a comprehensive design & installation guide, and a recognised related document for Acceptable Solution E2/AS1 of the NZ Building Code.
Many falls from heights are caused by a lack of planning. Dangerous situations can be improved by identifying, assessing, and managing hazardous situations.
Scaffolds are a common way to provide a safe work platform.
Edge protection is used to prevent persons, objects, or materials from falling.
Edge protection may be:

Safety mesh protects workers against falling through a roof while they are installing cladding; it should be used in combination with appropriate edge protection. For more information about using Safety Mesh, see https://worksafe.govt.nz/topic-and-industry/working-at-height/working-at-height-in-nz/.
Safety mesh should comply with AS/NZS 4389 Safety Mesh.
Safety netting describes fall arrest systems using temporary netting. This must be designed and installed in compliance with Worksafe: Best Practice Guidelines, Safe use of Safety Nets.
Mechanical Access Plant includes:
Safety harnesses may be of Total Restraint type or fall arrest type.
Total Restraint types are preferable, they protect a person from approaching an unprotected edge
Fall arrest or Positioning systems limit the distance a person can fall
All safety harness systems must be adequately anchored, and in fall arrest systems rescue planning must be developed prior to use.
These mitigate the effect of falls by providing an energy absorbing landing area. They are generally applied where potential fall height is low.
