I just stumbled upon this by pure accident and was pleasantly surprised! It turns out this looks to be a fabulous event and even better its free!
"Chromacon is an annual independent Illustration and Comics Arts Festival to be held in Auckland, New Zealand. It is a non-profit, community focused event that aims to connect a broad spectrum of Kiwi creatives and art-lovers together.
We aim to create the best annual showcase of the latest in homegrown illustration and comic art. At Chromacon, artists from all over New Zealand will exhibit original artwork from a range of mediums, styles, and genres. Each will also be selling self-published work in the form of original artwork, prints, comics, artbooks and much more."
If you are in Auckland on the 12th May I suggest you head along!
