Group managing director Mary Devine said the group's balance sheet and projected future cash flow remained strong. Stock levels were also well managed, she said.
When taking over the reins in April, Devine was tasked with continuing to build digital customer engagement, controlling costs, and improving market share in New Zealand and Australia. E-commerce accounted for 14 per cent of group sales in the first half.
Like other apparel chains, Hallenstein Glasson has had to contend with increasingly strong competition from cheaper online rivals such as Asos and it ditched its Storm branded stores in 2018 to focus on its two namesake brands.
Shareclarity managing director Daniel Kieser said he suspected Hallenstein Glasson would out perform other listed retailers full-year earnings.
"The reporting season has only just started, so we should know in a couple of weeks whether Hallenstein Glassons has truly out-performed the retail sector. I suspect it may have," Kieser said.
"Glassons maintained its growth in the second-half, which was better than we expected and better than many other New Zealand and Australian retailers."
Discretionary clothing retailers have had a tough two to three years, Kieser said.
"Noni B and Myer, for example, have seen flat or negative revenue growth since 2014 (excluding acquisitions) yet Hallenstein Glassons has grown its revenues by more than 30 per cent over the same period."
Hallenstein Glasson shares are up 1.7 per cent at $5.39 and have climbed 29 per cent so far this year, outpacing a 21 per cent increase on the S&P/NZX All Index over the same period.
The company will post its full-year earnings on September 27.
