Krukziener, out of bankruptcy on December 15 next year, is not a director or shareholder and is not banned from working so has been active on the projects opposite Aotea Square and the Town Hall.
"It used to be a pretty dead corner but now 22,000 people a day walk past this point from 8am until midnight," Krukziener said outside 350 Queen St, showing how the building had unrealised potential.
Floors in what was DFC House are being refurbished and a school could shift in, he said.
At 396 Queen St, Krukziener said 15 shops would be built and sold on the ground level.
Upper floors of the 19-level tower would be refitted and new lifts installed, and the entrance will be changed to give better access to Queen St.
Both buildings were bought from a Korean investor.
