You're probably hitting cached records at your ISP or somewhere.

I recommend using dig + trace for this sort of diagnosis work, it does
all queries directly, hence avoiding the problem or cached records.

dig +trace reports that diamondage.co.nz is working ok

diamondage.co.nz.       86400   IN      NS      ns3.maxnet.net.nz.

family.gen.nz is broken however,

family.gen.nz.          86400   IN      NS      ns3.win.co.nz.
family.gen.nz.          86400   IN      NS      family.gen.nz.
;; Received 90 bytes from 202.46.190.130#53(ns1.dns.net.nz) in 73 ms

family.gen.nz.          74197   IN      NS      ns3.win.co.nz.
family.gen.nz.          74197   IN      NS      family.gen.nz.
;; Received 106 bytes from 209.123.221.169#53(ns3.win.co.nz) in 349 ms

It looks to me like the .nz zone isn't providing glue for the
family.gen.nz record and neither is ns3.win.co.nz. ns3.win.co.nz doesn't
seem to be providing any authorative records either, so the domain is
currently unresolvable.
