"Of the 17 buildings, we've fully restored just over half," said the businessman, who is of Te Aupouri, Ngati Kuri and Te Rarawa descent, and has been made a companion of the New Zealand Order of Merit for services to urban redevelopment.
"We're close to starting on Australis and Nathan, the two most significant buildings on [Takutai] Square.
"They're on the agenda for this [coming] year," he said of upper-level office conversions, ground-floor shops and basement food and beverage operations.
"We're also working on two of the buildings beside Seafarers, Quay and Altrans, and we could start work in April. We're hoping to have a fresh food market in the ground and offices above," Cooper said, paying special tribute to chief executive Matthew Cockram, leasing and sales director Jeremy Priddy and marketing director Sarah Hull.
After a decade, Britomart now has 140 tenants, commercial, retail and food and beverage tenants, and buildings valued at $500 million-plus, but Cooper said it was not his most profitable venture.
"At one stage, we estimated $350 million, but well in excess of that has been spent. It's probably come out better than we hoped for. It's more active. We thought we would struggle harder to fill it," he said. "We never thought we would have it 100 per cent occupied."
High St retailers have mourned the stampede to Britomart but Cooper said he did not target them.
"Every area is competitive. You don't go after another district. You're basically looking for tenants and you have a particular category in mind which was high-end New Zealand fashions and they came from everywhere, not just High St," he said.
"Where they come from is secondary to who they are. People like World went from more of a back street presence to a front of street presence."
