I've got two Griselinia littoralis shrubs in containers. Some of the
smaller, younger leaves on both plants have turned partially black,
and the black parts are limp. Would that be due to all the rain or
recent weeks - or something else?

Same has happened to my long-established griselinea hedges. It's not
rain; just a frost or hard chill when new season's early growth was
too tender to take it. As you can see, only new shoots are affected.
You don't need to do anything, as the weather warms up they will
sprout again.

I guess you could be right... particularly, since the black leaves on both
shrubs, are on the same side (presumably the windward side on a
particularly cold night). We did have hail storms for a couple of days, so
there must have been some pretty cold air around.
