Three Gap Inc. brands are the latest tenants to sign leases at a planned $500 million Kapolei mall.

Old Navy, Gap and Banana Republic have agreed to open at the complex known as Ka Makana Alii, the 1.4 million-square-foot regional mall opening in West Oahu in 2016.

Other retailers already on board include Macy’s, H&M and Forever 21.

Mall developer DeBartolo Development signed last week a lease for the site with the state Department of Hawaiian Homelands.

Old Navy is expected to occupy 12,500 square feet in its fourth Hawaii store while Gap’s fifth location will be 7,200 square feet. Banana Republic will open a 6,500 square foot store, its sixth location in the state.

These will be the first West Oahu locations for all three retailers, which will offer women’s, men’s and children’s apparel, as well as footwear and accessories.
