A spokeswoman for The Warehouse said the stores will be opening at 9am to allow time for a team meeting to discuss a proposal regarding the way our stores operate.
The stores normally open their doors at 8am.
The spokeswoman said "we won't have anything else to share before we've spoken to our team members tomorrow".
She would not comment on job losses, but First Union general secretary Dennis Maga said the new operating model could lead to fewer stores and fewer jobs.
The union, which represents about 2000 retail staff at The Warehouse, had received some information about the new model in confidence and would issue a statement following the meeting, he said.
"Members are expressing their frustrations. They would like to know and understand what this process is all about. They need to understand if they will keep their jobs after the consultation.
"They also need to know whether they still have a store to work in," Maga said.
In an NZX announcement on June 8, the country's largest listed retail company said it was moving to an agile business model, which would "likely see a reduction of around 100-130 roles" in its Northcote head office.
In addition to this, it plans to close six The Warehouse, Noel Leeming and Warehouse Stationery stores. The stores that face closure include: Noel Leeming Henderson Clearance Centre and Tokoroa store, The Warehouse Whangaparaoa, Johnsonville and Dunedin Central stores and the Warehouse Stationery Te Awamutu store.
This follows earlier announcements that it will close its The Warehouse store in Birkenhead in July, and Noel Leeming stores in Papanui and The Palms in Christchurch.
The company said the proposals would see around 700-950 roles or 410 fewer full-time equivalent store roles as a result of store closures.
The group has already commenced the consultation process for job cuts in its head office as it powers on with its plans to go agile from August 31.
Warehouse Group chief executive Nick Grayston said last month the impact from Covid-19 had "made it even more clear that Agile is the right model for the group".
