That has nothing to do with what's in pg_collation. It means that
you don't have this locale definition installed at the OS level.
Probably "locale -a | grep NZ" will not find it. So you need to
install the relevant OS package. You didn't say what platform
you're on, so I can't guess which package that is; but it's
something related to libc, not Postgres.
