"We're doing something similar in Wanganui, with the two stores side by side but with a shared warehouse. Think of it as two restaurants but one kitchen," he said.
He said the move was happening because leases on the existing stores - Briscoes in St Hill St and Rebel Sport on the St Hill St-Ridgway St corner - were coming up for renewal.
"One of the criticisms with both our stores had been around parking but this new property will give us plenty of parking in front, with the stores set back from the road," Mr Duke said.
Briscoes Group would again be the tenant in the complex, being built by an unnamed local developer.
"We hope to be in there by September or October this year," Mr Duke said.
"A lot depends on how fast the district council gets the consents signed off."
But he said the company had visited Wanganui and the district council had been "very proactive" and had shown it a number of potential sites.
"They are obviously very keen to see some development go ahead." Mr Duke said the group had been looking for new premises for the Briscoes homeware store for at least three years, because it was too small.
"I'm terribly excited about what we've got planned for Wanganui and we expect it to have a marked impact on turnover in both stores in your city," he said.
With that in mind, they were anticipating having to take on more staff in both stores.
