Inter-tenancy walls between apartments & Fire Design

Inter-tenancy walls between apartments & Fire Design

Inter-tenancy walls between apartments & Fire Design

NZ Building Code B1/VM1 2.2.4 states that a faceload of 0.5kpa "after" a fire.
I'm trying to keep my building timber light framed apartments. I assume "after" a fire means that the fire rated wall linings have not yet disintegrated and that the fire is already suppressed. Assuming this, wouldn't it be a sound and reasonably assumption that the STRUCTURE behind the linings are more or less adequate and therefore the shearwalls are OK and therefore the 0.5kpa faceloading on the fire rated bits is an easy task.

As I browse inter-tenancy products on the internet, they have these proprietary clips to structurally tie the studwalls together (presumably to tick the box for 0.5kpa faceload).... are they even necessary if the intertenancy wall assembly itself is fire-rated?
