My colleague daniel has already gone home, so I'll chime in here as
the person who included nic.ch in the ch zone a few years back :)

nic.ch is in the ch zone itself. So it's not a zone of its own.

You will find it in whois so that people see that it's not available
anymore.

Thanks. I suspected something like that, so I compared this to other 
ccTLDs and it's different there, e.g. for nic.fr and denic.de you get NS 
records:

dig @ns1.denic.de denic.de ns
dig @ns1.nic.fr nic.fr ns

Why is this different for nic.ch?

To avoid unnecessary redirection for the resolution of the ch name
servers, which are part of the nic.ch domain (a.nic.ch, b.nic.ch
etc). If nic.ch were a zone itself, we would need to make it as
available as the ch zone to avoid certain failure modes.  This would
suggest to host it on the same set of servers that ch lives on.
That's achieved automatically by making nic.ch part of the ch zone in
the first place.

The se TLD does the same thing with ns.se, btw.
