Country Road, Levis, Esprit and Tarocash are some of the new-to-Dunedin clothing retailers who had signed leases, Wall Street project manager Dave McKenzie said.
Lush, Vodafone and Life Pharmacy were also opening outlets, bringing the occupancy rate of the building to 64%, he said.
This number was expected to increase, with more tenants likely to commit to the Dunedin City Council-funded project in the next few weeks.
Almost all the retailers in the development were new to Dunedin.
"They believe coming here will be a viable investment for them, so it is a good start."
One of the stipulations of the project was that it did not take retailers from existing Dunedin areas. However, several stores had expressed interest in opening up new branches at Wall Street.
"We are considering a couple of stores, but we have to get a written understanding that they don't close their other store down the track."
The three-storeyed building would consist of retail space on the ground floor, with car parking on the first and second levels.
Additional retail space could be added to the first level, depending on demand, he said. Three food outlets were among the tenants confirmed for the ground floor.
The project was on target to be completed before its March 7 opening, largely thanks to the construction team moving to a six-day week timetable, after the discovery of an historic causeway on the site.
More than 40% of the causeway had been removed from the site and would be preserved in a glass case in the development's courtyard.
The remainder had been buried in situ, he said.
If the manuka could not be preserved in time for the opening, it was likely a temporary model of the causeway could be used.
The discovery of the causeway had caused headaches for not only the developers, but also would-be tenants, with its original location in front of the entrance to Life Pharmacy.
"They were a little concerned it could create problems for their store with people looking at the causeway," he said.
Fears the discovery of the causeway may lead to delays for the project had been allayed, when it was revealed more than half of the wood was unable to be preserved, requiring it to be preserved in situ.
Work was almost complete on the George St frontage, which would include etched-glass images of the former Dunedin Stock Exchange.
Construction was expected to be completed by January before final fit-outs.
