The Shoten/Techart TZE Nikon Z-mount to Sony E-mount adapter (mounts converter is probably a better description) will be officially announced at the 2019 CP+ show in Japan next week according to a recent Facebook post.
Note that this is a 2mm adapter conversion ring, not a standalone adapter and it should be used in conjunction with existing/other Techart Pro autofocus adapters. For example: if you want to autofocus a Leica M lens on a Nikon Z camera, you will need the Techart TZE mount converter (Nikon Z -> Sony E) and a second Techart autofocus adapter (Sony E -> Leica M):
Similar, if you want to use a Canon EF lens on Nikon Z camera, you will need the Techart TZE mount converter (Nikon Z -> Sony E) with a second adapter for the Canon conversion (Sony E -> Canon EF):
