What version of nsupdate are you using? That syntax doesn't work for me:

% nsupdate

Normally to make changes to the NS records in the parent zone, you need 
to give the "zone" directive to nsupdate, e.g.

% nsupdate
zone test.com.
update delete test.com. ns host1.test.com.
send
%

If you don't tell nsupdate to update the records in the parent zone, 
then it'll identify the zone to be changed as the "closest enclosing 
zone" of the name being updated, which would be the child zone, which 
you don't want.
