A new store by Saks Fifth Avenue at Ala Moana Center is slated to open next spring but won’t be a full-line department store for the luxury New York-based fashion retailer.

Saks announced today that its plan to move into the state’s largest shopping center will involve a 41,000-square-foot OFF 5TH, the discount outlet of Saks.

The planned store will occupy only about 20 percent of the 210,000-square-foot space in the mall’s mauka wing vacated last week by Nordstrom, which simultaneously opened a new 185,000-square-foot store in a new Ewa wing that also includes Hawaii’s first Bloomingdale’s store that opened in November.

Officials with Ala Moana could not immediately offer any comments on the planned addition by Saks or what is planned for the remaining empty space spanning three levels and fronting Kapiolani Boulevard.

Earlier this week, the Star-Advertiser reported that Saks had signed a lease for the former Nordstrom space based on a memorandum of a lease filed by Saks at the Bureau of Conveyances. The memorandum did not indicate that only a part of former Nordstrom space was being leased.

The addition by Saks will give the retailer two OFF 5TH stores in Hawaii. The other is at Waikele Center. Saks also is building an 80,000-square-foot full-line department store at a redeveloped International Market Place in Waikiki that is slated to open in August.
