Armageddon Expo has transformed Trustpower Baypark Arena this weekend into an amazing array of pop culture entertainment with the best in gaming, comics, anime and cosplay.

The lineup of celebrity guests and the opportunity to dress up in costume brought thousands out on Saturday to experience what many are calling ‘Bayofgeddon', with more expected for Sunday.

People come to the expo for all sorts of reasons.

One person said 'The only reason I come here is to hang out with my friends in crazy costumes. It's good fun!”

It's also an opportunity to entertain children, and showcase the creative work costume designers and artists have done over the last 12 months.

There's plenty of merchandise and activities.

'I love all the costumes and I love all the things you can buy here,” says another dressed up character.

'I like the personality you can give to a costume. It's enjoyable how people take on the character.”

The popular event was packed with people enjoying the shooting gallery, viewing costumes, and going shopping amongst the vast displays of merchandise.

New Zealand comedians and stars of ‘What We Do In The Shadows' and ‘Wellington Paranormal' Mike Minogue and Karen O'Leary made an appearance for a panel as well as a signing and selfie session. Luke Baines, Lotte Verbeek, Aimee Garcia and Dominic Keating also delighted the crowds attending the panels.
