The Warehouse employees will learn their fate on Monday morning, as the company plans to axe about 1000 jobs.
Stores are opening an hour later so staff can attend an 8am meeting.
Last month, The Warehouse chief executive Nick Grayston said the company was adopting an agile working structure, which could see more than 1000 jobs cut across the country - nearly 10 percent of the workforce.
He said it could see six stores close across the whole Warehouse group; Noel Leeming in Henderson and Tokoroa, The Warehouse stores in Whangaparaoa, Johnsonville and Dunedin Central, and Warehouse Stationery in Te Awamutu.
Prime Minister Jacinda Ardern earlier said she was "angry" at the proposed job cuts and expected The Warehouse to do more to keep staff employed.
