The isdn*.vodafone.co.nz name servers are authoritative for www.vodafone.co.nz, but don't have an A record for that host.

Why the "isdn" though? Just a remnant of the old days, or is Voda running its DNS over ISDN lines still?

Update It's the lot in the vodafone.co.nz domain, and not just the website. Headline changed to reflect this.

Update II The problem is sorted now...
