''The facility is designed to support business efficiencies and best practice health and safety procedures.
''We're looking forward to bringing together the 30 employees spread across our two current sites,'' he said.
Confirmation of the site's first tenants came after the Otago Daily Times last month reported Calder Stewart was seeking non-notified consent for stage one of the site's redevelopment.
That would result in a single-storey, 3875sqm industrial warehouse, 302sqm office and yard built on one corner of the site, extending northeast from the Burns and Neville Sts intersection.
Once the ''anchor'' tenants were in place, attention shifted to the development of the rest of the site, a Ryder Consultants report, for Calder Stewart said.
Construction of the new facility was expected to begin later this year, although it was not yet clear it would be completed.
Calder Stewart bought the old ground from the council for $3.5 million in 2013 and demolished most of the old stadium later that year, leaving only the historic Neville St turnstile building.
The new office would overlook the turnstile building, which the council planned to make the centrepiece of a pocket park.
