While The Warehouse continued to trade well in the apparel category, with sales and margin increasing from a year earlier, some seasonal outdoor categories such as gardening, outdoor furniture and BBQs were impacted by the wet weather in the early part of Spring, the company said.
Grayston said he was disappointed with the performance of Warehouse Stationery which he attributed to a systems integration between it and The Warehouse during the quarter.
"This change caused some disruption to the business, particularly in stock availability which impacted sales in the quarter," the company said. Some high-value sales categories including computer products and communications underperformed during the quarter, contributing to the sales decline, it said.
Still, gross margins increased as the sales mix changed towards higher margin categories and the Stationery business is expected to return to normal trading levels as the business heads into the critical Christmas and Back to School periods, it said.
The company added one Noel Leeming store in Auckland during the quarter, and the chain reported strong growth in the communications, audio and whiteware categories.
Its Torpedo7 unit had strong sales at its physical stores and through the 1-day segment, partially offset by decline online sales, particularly in the Australian market, it said.
Warehouse Group said its online sales increased 9.2 per cent to $46.6m from a year earlier, and now make up 7.2 per cent of all sales.
The company ended the quarter with 93 The Warehouse stores, 78 Noel Leeming stores, 69 Warehouse Stationery stores, and 11 Torpedo7 stores.
Warehouse Group didn't provide an earnings outlook with today's release and has previously said it expects to provide an annual forecast at the end of its second quarter.
Its shares last traded at $2.10 and have shed 29 per cent the past year.
