Apparel retailer Hallenstein Glasson Holdings Ltd has announced plans to sell its HBKGirl chain on the back of a 20 per cent year-on-year rise in half-year profit.

The Auckland-based company said it had made an agreement with an unidentified party to purchase the chain for an unspecified amount.

The sale is expected be completed by April 30.

"There will not be a material impact on future earnings of the group as a result of this divestment," the company said in a statement.

According to Hallenstein, current HBKGirl staff would be retained by the buyer or offered employment elsewhere within the company following the acquisition.

Meanwhile, Hallenstein has posted a net profit of NZ$7 million for the six months to February 1, compared with a net profit of NZ$5.8m in the same period a year earlier.

The company, which partly attributed the result to a stronger local dollar, also posted relatively unchanged sales revenue of NZ$90.7m for the first half.
