Hello! I’m Matt and among other things I’m currently wearing the NZLARPS South Island Regional Director and the Cerberus Organiser Committee hats. As @IdiotSavant said, feel free to send any questions through to cerberus@nzlarps.org or cerberus.larp.convention@gmail.com and we’ll reply as soon as we can
To answer your earlier question I’m not aware of any organised larping groups in Invercargill,but as luck would have it I am in Invercargill this coming weekend so if you want to meet up, drop an email through!
