The 15 staff moved into a temporary and much smaller site at Rotorua Central while the new store was being built.
Mr Gianotti said the new building was slightly bigger than the one it was replacing.
It has sprinklers and a slightly different layout to the previous store.
He said well over $2 million had been spent on the rebuild and some of that had been covered by insurance. An additional four to five staff had been employed.
Mr Gianotti had nothing but praise for the staff.
"Initially, it was traumatising for them ... we had a new [temporary] store in 30 days. They just got on with it."
He said staff had done a fantastic job of making the best of the situation. "It's a credit to them."
Completing the rebuild in a year and three days was a huge achievement, he said. A grand opening was planned for early in the new year.
