"I've been coming to New Zealand for science fiction conventions for almost 30 years. People find New Zealand a wonderful destination - we didn't just want to have Auckland and Wellington on rotation. A lot of people are staying for the whole week so they can experience real New Zealand in Rotorua."
Mr Ivamy said the local community had backed the event.
"We had the function at Atlantis Books, and most of the steampunk tea-type activities are being run by the Rotorua steampunk community."
Guest of honour and retro-futurism author Gail Carriger said Rotorua seemed to enjoy the steampunk aesthetic.
"People have been responding really well. It is a fun aesthetic to see, and there's more of that small town feel here - people are more comfortable stopping us for photos and to say hello."
Mr Ivamy had plans to bring the World Science Fiction Convention, or World Con, to Rotorua. This year's convention acted as a test run for staging a larger convention here, he said.
"The Loncon 3, or London World Science Fiction convention, had 9000 attendees. We think we could get 2000 to 3000 people here for it."
