There have been a few new TLDs signed from the start before this "dawn".
I may have missed some, but these certainly were:
sx on 2011-12-10 (ccTLD for Sint Maarten)
post on 2012-08-08
xn--mgbx4cd0ab on 2012-09-21 (IDN for MY = Malaysia)
xn--l1acc on 2013-08-18 (IDN for MN = Mongolia)
(the dates may suffer from off-by-one-or-even-more errors).
The last of those is a sad case, however, as a few days after its
initial appearance they performed a KSK rollover, omitting to change
the DS records in the root zone, and the zone has failed validation

Part of the problem is that only one NSEC3 record is returned - the
one covering the zone apex, which doesn't necessarily cover the
name queried for. But validation seems to fail even in cases when
the name is so covered.
