The Warehouse Group is cutting around 270 roles from within its head office team

The move is part of a drive to push down the cost of doing business, with several administrative functions set to be outsourced overseas.

The company is expanding its partnership with software company Tata Consultancy Services to help with the likes of call centres and payroll.

CEO Mark Stirton says tough choices need to be made to return the group to sustainable profitability.

The changes will result in redundancy costs of about six million dollars this financial year.
