If you're only after opponents in New Zealand, you'll have a tough time.
On the other hand, if you join in Aussie games, you'll find a far larger playing group. The regular Aussie groups play 3 seperate continous games, and if you're interested, keep an eye on the threads for when a new game starts. We already have one kiwi playing with us, a second would be welcome, providing your connection is ok, and you're reliable.
