Two dozen more Kmarts will be refurbished with a new format that moves the cash registers back to the store entrances, and the group is also trialling a new concept store for home goods.
Kmart Group managing director Aleksandra Spaseska told analysts on Wednesday that 16 of the roughly 300 Kmarts in Australia had already been converted to the "Plan C+" format, which features entry and exit gates and relocated cash registers.
"It is delivering improved space allocation, better visual merchandising, and an enhanced beauty experience," Ms Spaseska said.
The format is also driving higher sales through increased cross-shop between departments, with shoppers buying more items per basket, she said.
As a result Kmart Group is increasing its investment in the transformation program and expects to have 40 stores trading in the new format by the end of 2026/27.
