Those in the rag trade have felt it acutely, with government figures showing consumer prices for clothing have shrunk 1.4 per cent since 2011 when Popplewell took over the reins of Hallenstein Glasson, while the value of annual sales was up 2.8 per cent indicating margins have been squeezed through that period.
For Hallenstein Glasson that's seen the shares fall to $3.04 from $3.83 when Popplewell was appointed, having peaked at $5.85 in April 2013.
Popplewell said he anticipates the next five years will see "major technological advances" with changing customer demands.
"We need to be equal to any international retailer to be able to compete," he said. "It's not just about one element - it's everything - product, marketing the stores and finding the right people to lead your brands."
Hallenstein Glasson's ecommerce offering was expanding at an annual 30 percent pace, and "becoming a significant part of the business," he said.
The retailer reported a 21 per cent drop in profit to $13.7 million on a 0.9 per cent increase in sales for the 2016 financial year, reflecting a loss from its Glassons unit in Australia and weaker earnings from its flagship menswear chain.
The company's board has started an international search for a new chief executive.
