Mark,
You can find the file here in Library 1, New uploads.
In general, to find a file, GO AMIGAFF (FileFinder) on CIS. That will let
you search all Amiga forums at once. This is the listing for LZ:

LZ is the fastest LZH archiver and extractor available for the Amiga! It
also produces smaller files than ANY other archiver. LZ is compatible with
both the original Lharc and the new LHA. LZ is currently the only
utility available for the Amiga which can archive or extract in new, more
efficient, LHA archive format. By Jonathon Forbes. version 1.92 (fully
functional)
