The Department of Conservation (DOC) and the Wellington Zoo worked alongside the police to remove the birds from the shop a second time.
The DOC checked the penguins for injuries and signs of stress, and both were found to be in "good condition," according to Ward.
The penguins were released into a more appropriate nesting site by the harbor. However, authorities fear that the sneaky birds may be on the run yet again, as their assigned nesting box has been found empty two days in a row.
Staff members at Sushi Bi are checking under the shop and keeping an eye on the salmon should their feathered guests return.
