Unless you are really clueless and have authoritative name servers that allow recursion and you encourage your customers to do lookups on them. That way you serve them stale data until somebody or thing removes the domain allowing the new world view to appear.
Which most (all?) the major ISP's do. If they didn't you wouldn't need to email them to remove the records (they wouldn't matter once the .nz registry was updated to point away). Not only is this bad practice & adds extra workload to the helpdesk / DNS admins, its also very poor security for customers using those DNS servers. Just look at what happened with msn.co.nz earlier this week. Lets say i'm a naughty person who says I want to host $bank.co.nz on my purchased web space provided by $ISP via their account portal.... or I call the ISP helpdesk who happily help me by setting up the DNS settings, i've now successfully hijacked all that ISP's traffic to said $bank & can do all manner of nasty things. This is a serious flaw waiting to be exploited & ISP's need to take it seriously & fix it. Words are my own ... not my employers yada yada yada.
