I'm still pointing and laughing.

DNS registrations are done by name, DNS resolvers are referenced by IP.
So all they need to do is change the IP addresses that
"alien.xtra.co.nz" and "terminator.xtra.co.nz" point to. Turn off
recursive service at those new addresses, and stop making excuses for
failing to meet industry best practice for well over a decade.

The only complication is where domain owners used their own NS records
for registrations and publish their own glue records into their upstream
registries/zones. I'm pretty sure Xtra didn't normally allow that, so I
wouldn't imagine there would be very many.
