The Greater Waikato region covers everywhere south of the Bombay Hills and north of Taupo, including Hamilton, Rotorua and the Bay of Plenty. Currently, there is an active larp community in Hamilton which is enjoying rapid growth. Hamiltonians get together for one-off games, to practice live combat fighting and to organise travel to larps in other regions. Starting a new larp campaign in Hamilton is always a possibility too.
You can join the Facebook group (external link) or check out the Hamilton forum on Diatribe (external link) to find out what's happening, or drop an email to the marketing officer and they'll keep you updated.
Fallout: Dead Zealand (external link) is a post-apocalyptic larp campaign based on the Fallout Universe by Bethesda Software with a distinct NZ twist and flair. Get involved by joining the Fallout: Dead Zealand Facebook group (external link) .
