Last November NZRPG said high bank borrowing costs, falling house prices, low pre-sales and delays getting contract building prices had prompted the business to delay building the 115 apartment units and 20 new shops.
Barbour said yesterday before a shopping conference:"We've never given up on it. But we've postponed one of the first projects."
The business had submitted an amended resource consent application to Auckland Council for the nine-level block, he said.

"We're still playing with that. The first thing is probably some additional residential - smaller than the first one, about 60 apartments. We're just going through the resource consent process.
"We've got an overall resource consent but this is for more specific buildings," he said of NZRPG's plans for the site.
"The issue we had was the classic situation where it's not investors but owner-occupiers. It's a big decision to sell their home and relocate. It's a chicken and egg situation," he said.
Asked when work might begin, he said: "It depends on the consent process.
"We're expecting to get it in the next month or two. It could start early to mid next year."
Asked about changes to plans for the first block, he said: "It's better. We're looking at making the decks into summer and winter rooms. A lot of apartments, the decks can't be used. They're nice on the first day but with the price of apartments, you want to be able to utilize the space all year around, so it will be loggia-style."
On prices, he said: "They'll be two bedrooms around $1.5m up to $3.4m to $4m."
The project was strongly opposed by the Milford Residents Association and went for an extended Environment Court hearing.
In 2013, the spectre of more than 500 people living in a cluster of towers rising up to 16 levels dismayed opponents although the height was subsequently lowered.
