Have a look at http://www.cosc.canterbury.ac.nz/research/reports/TechReps/1999/tr_9901.pdf for a scientific study (from 1999) of the topology of the country's main NTP servers. (A bit dated as GPS is much more widely available now).
There is a pool of NewZealand servers at nz.pool.ntp.org, which provides RoundRobin DNS access to publicly accessible NTP servers that have agreed to be part of the pool.
The Measurements Standards Laboratory at Industrial Reasearch Limited run a HP5071A caesium atomic clock which is part of the New Zealand time standard. This server is available at the address msltime.irl.cri.nz. Read more details.
TelstraClear 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 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 synching 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.
Some NewZealand ISPs have NTP servers for their customers:
or you could try querying your ISP's DNS servers with ntp or ntp1.
Many of NewZealand's Universities also have public time servers such as:
For a long time WaikatoUniversity had public NTP servers. They are still available but no longer publicly accessible.
Your best bet for a small home or office network is to set your server to nz.pool.ntp.org or pool.ntp.org, which will use RoundRobin DNS to choose one of the many servers now registered with that project.
Germany also has a pool.ntp.org entry: <tt>de.pool.ntp.org<tt>
If that doesn't work for you, you could try some of the following servers:
You might also want to look at a very extensive list of public German NTP servers.
As mentioned above, pool.ntp.org is a RoundRobin DNS for many NTP servers. Try cc.pool.ntp.org, where cc is a country code.
