Eric, Thanks for the complete example below, but I'm not sure what you are trying to solve?
It looks like the netregistry.net servers don't have zone data loaded even though they are supposed to be authoritative. Your best bet would be to contact them and point out it appears some zone data was lost when service was transferred. Trying to use Google isn't going to help if the data isn't on the designated authoritative servers. Hope this helps.

And there are a number of domains (not sure if all) host at ns1/ns2.planetdomain.com ns point to ns1/ns2/ns3.netregistry.net. However these netregistry.net do not host these domain. Then if the records of these domain expired and refresh from these netregistry name server, they will get error. For example: domain "carlajohnson.com.au": $ dig +trace ns carlajohnson.com.au ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.37.rc1.el6 <<>> +trace ns carlajohnson.com.au ;; global options: +cmd . 399916 IN NS e.root-servers.net. . 399916 IN NS j.root-servers.net. . 399916 IN NS i.root-servers.net. . 399916 IN NS h.root-servers.net. . 399916 IN NS b.root-servers.net. . 399916 IN NS c.root-servers.net. . 399916 IN NS d.root-servers.net. . 399916 IN NS a.root-servers.net. . 399916 IN NS m.root-servers.net. . 399916 IN NS l.root-servers.net. . 399916 IN NS g.root-servers.net. . 399916 IN NS k.root-servers.net. . 399916 IN NS f.root-servers.net. ;; Received 492 bytes from 10.68.201.185#53(10.68.201.185) in 9 ms au. 172800 IN NS v.au. au. 172800 IN NS w.au. au. 172800 IN NS a.au. au. 172800 IN NS b.au. au. 172800 IN NS x.au. au. 172800 IN NS y.au. au. 172800 IN NS u.au. au. 172800 IN NS z.au. ;; Received 489 bytes from 192.36.148.17#53(192.36.148.17) in 71 ms carlajohnson.com.au. 14400 IN NS ns1.planetdomain.com. carlajohnson.com.au. 14400 IN NS ns2.planetdomain.com. ;; Received 89 bytes from 37.209.194.5#53(37.209.194.5) in 304 ms carlajohnson.com.au. 3600 IN NS ns2.netregistry.net. carlajohnson.com.au. 3600 IN NS ns1.netregistry.net. carlajohnson.com.au. 3600 IN NS ns3.netregistry.net. ;; Received 106 bytes from 203.55.142.5#53(203.55.142.5) in 327 ms $ dig @ns1.planetdomain.com soa carlajohnson.com.au ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.37.rc1.el6 <<>> @ns1.planetdomain.com soa carlajohnson.com.au ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 18145 ;; flags: qr aa rd; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; WARNING: recursion requested but not available ;; QUESTION SECTION: ;carlajohnson.com.au.
