For those attending there will be free Wi-Fi available provided by the council, the AP will be in Hinemoa Park.
Also there is an iphone app called "HamiltonNZ" available in the iTunes store which you could describe as a tourism app but has a complete guide for the event incl a live twitter feed.
Buses again are free so no need to worry about Car Parking
Just hope it does not rain!
