Hallenstein Brothers has recorded sales of $45.30 million for the six-month period to February 2022.
The result, which includes Australia and New Zealand, represents a 12.4% sales decline against the same period last year.
New Zealand lockdowns had a significant impact on the store performance for the brand.
Hallenstein Glasson Group CEO Stuart Duncan said consumer habits had changed as a result of the pandemic.
"It was pleasing to see growth in casual categories, which largely offset the move away in menswear from more formal dressing.
"COVID-19 has been the trigger for a significant shift in consumer habits with a far more casual approach taken to what would traditionally be worn in the office and at events, and the business has been able to pivot and adapt accordingly.
"Casual categories continue to outperform over the financial year with the team continuing to focus on current trends and ‘must have’ products."
