My idea was to use a callback too hook port 80 and use a perl script to reverse lookup the ip address and look for .nz at the end and pass fail there after. It seems a simple idea, very slow and I do not know how it would go with recursive entry, but for what I wont it would do. Did you look at a similar idea first before filtering the subnets?

The solution does not need to be very fast, handle more then one high level domain or any other ports and is not for commercial usage.
Any solutions?

I am (slowly) working on a solution for people who do not have availability to the international/national junction at an ISP.
Hope this helps, it needs testing if you are keen
