Long-term staff at the Warehouse Group will notice an extra $30 to $60 a week in their pay packets from the start of next month.
The company is introducing a career retailer wage for people who have worked 5000 hours or more and completed the required training.
Between 7000 and 8000 people work full-time for the Warehouse Group, and about 3800 workers will initially qualify for the career retailer wage.
Chief executive Mark Powell says 200 extra staff should qualify for the wage each quarter, and by the end of the year 60% of full-time staff will be earning the career wage.
Mr Powell says he hopes the new wage will show people that retail can be a good career.
He says the career retailer wage will cost the company $6 million over next two years.
