Error in named configuration

I am migrating to a new server and have run into a Bind error:

Failed to start service : Failed to start BIND : Starting named: Error in named configuration: zone localhost.localdomain/IN: loaded serial 0 zone localhost/IN: loaded serial 0 zone 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa/IN: loaded serial 0 zone 1.0.0.127.in-addr.arpa/IN: loaded serial 0 zone 0.in-addr.arpa/IN: loaded serial 0 zone hostwizard.org/IN: NS 'server.hostname.org' has no address records (A or AAAA) zone hostname.org/IN: not loaded due to errors. _default/hostname.org/IN: bad zone

I see this warning at the top of the DNS Records page for hostname.org (account associated with the server host name):

Warning - errors were found in this domain's DNS records : The following errors were found in the DNS records : zone hostname.org/IN: NS 'server.hostname.org' has no address records (A or AAAA) zone hostname.org/IN: not loaded due to errors.

I can't spot whats wrong - Suggestions please.

Thanks, Brian
