What will happen to Greater and Permanent HQs beyond $20b bank merger?

The Greater Bank head office in Hamilton, on the corner of Beaumont and Tutor streets (left), and the seven-storey Newcastle Permanent head office on King Street in Newcastle West (right).

It's been one year since the $20-billion merger between the Newcastle Permanent and the Greater Bank, and the new entity has seen a 15 per cent increase in customers.

Collectively, the new organisation is known as Newcastle Greater Mutual Group - or NGM Group for short - and is looking to expand its footprint well beyond the Hunter Valley.
