In 1901, a modern flagship store designed by architect Goldwin Starrett was opened at 609 Broad Street by Military Park in downtown Newark.

The firm did not enter the growing mall market in New Jersey until the 1970s, and this cost the chain valuable time in keeping up with its competitors.

Although the Westfield location was attractive, Hahne's lacked the customer base to compete with the nearby Lord & Taylor in Millburn, Saks Fifth Avenue in Springfield, and Bonwit Teller, B. Altman & Co and Bloomingdale's in Short Hills.

The stores below that Kane opened are still operated as Lord & Taylor locations, or are occupied by the chains that bought them, while the three that he inherited are all gone except for Westfield.

In 1978, parent ADG appointed Alan Kane, a graduate of Wharton School of Business, as CEO of Hahne & Company.

Kane oversaw the planning and opening of two new locations (Woodbridge Center and Rockaway Townsquare), and he steered the company toward a more focused, upper-market clientele.

May contemplated running Hahne's as a more contemporary focused chain that would compete with Bloomingdales, but Kane left the brand after a management shakeup had changed the overall direction of the company.

In January 2013, after sitting empty for almost 30 years, it was announced that the Newark flagship store would be renovated with a Whole Foods Market and retail arcade on the ground floor and 83 residential units above.
