The Southland Business Chamber and Coin South came together to set up a business and innovation hub at the former SIT Downtown in Don St.
Chamber chief executive Sheree Carey said the idea was to create a space for businesses in Southland to thrive — from an idea to inception.
"So if you’ve got a start-up or just an idea for a business, you can come here and the Coin team will talk you through it.
"Once you’re established as a business, the chamber will be able to help you with support," she said.
"It is a business one-stop shop right in the heart of the city."
The event on Wednesday showcased the variety of businesses across the region — from breweries to local producers and even pole dance performers pouring drinks for the guests.
Ms Carey said they wanted to have a place in the city centre as the chamber board wanted to support the redevelopment of the area.
"Not only does Invercargill have a heart of a city it now also has a brain."
