Cheers, a 8mm nut on the end of a piece of cotton, dropped down the cavity
through a 10mm hole also found the noggin. Old technology, I know, but it
did the trick.

When you need to pass a noggin in a stud wall, don't remove the plasterboard
completely from the front. All you need is a small slot that you can cut with a
modelling knife, but only on three sides of the square, or oblong, that passes
the noggin. You leave one edge intact so you can fold it back into place over
the cable and hide it.

The top or bottom edge is the best to leave intact, and you can gently break the
plasterboard after three sides are cut through. Check out the noggin a bit with
a wood chisel to accept the cable, and then fold the plasterboard back into
place and patch it up.

I've even used wood glue around the edges of the plasterboard to hold it in
place tightly before skimming over with a wet mix of finishing plaster to hide
it again. It makes the job a whole lot easier than having to try and patch an
open hole in a plasterboard wall.
