Clear generously provides a stratum 1 NTP server for public use:
# bigben.clix.net.nz
However, you really shouldn't synchronise to a stratum one server for your small network - if everyone did that then the the server would probably need too much bandwidth. Please read http://list.waikato.ac.nz/pipermail/nznog/2001-October/003705.html. The difference in accuracy between syncing to a stratum 1 server and a lower stratum server is negligible!
+For example, read http://www.cs.wisc.edu/~plonka/netgear-sntp/ - in summary, !NetGear hard-coded a public NTP server into some of their
+consumer products, which eventually ended up using hundreds of Mbits/second of the university's bandwidth, even after they were forced to shut down the server.

For a long time WaikatoUniversity had public NTP servers but no longer provides public access.
Your best bet for a small home or office network is to set your server to
-"pool.
nz.ntp.org" or "pool.ntp.org", which will use DNS to choose one of
+"nz.pool
.ntp.org" or "pool.ntp.org", which will use DNS to choose one of
the many servers now registered with that project.
