The Warehouse is expecting big things from its new financial services business, which is expected to launch before the end of the year.
The retailer is keeping most of the details about the new business under wraps for now, after last year's purchase of Diners Club New Zealand.
It has a $600 million finance book in a joint venture with Westpac Bank.
Warehouse chief executive Mark Powell said it wanted to grow the business, but Westpac did not.
Mr Powell said a fully-owned finance services operation will go hand in hand with the group's diverse retail brands.
"The real change is when we bought Noel Leeming. It changed the scale of potential products that require good, ethical financial services to be aligned with them to drive sales."
Mr Powell said the start-up costs for the finance business will dent its bottom line in the short term, but expects it will be earning about $30 million a year in gross profit, within the next to five to six years.
