I am not sure they will grant any expections to this rate limit.
Well, during my time as a registrar, they were certainly quite happy to
remove the limit, providing no abuse was occuring.
IIRC the reason it was instated in the first place is because some overseas
[spam/hack]ers were doing massive numbers of DNS queries using ISP's 'Check
a domain here and register now!' forms on their websites causing the whois
server to get a little overloaded.
If you'll notice there was actually a jump in the number who suddenly
implemented one of those captcha verification codes on their sites a while
ago - this is why.
IIRC they were just running through the exact same text list of domains via
quite a few web forms.
I don't see any reason why NZRS couldn't add your IP address to the
