Chief executive Nick Grayston said the company was adopting an agile working structure, which would see the head office workforce drop by between 100 and 130 jobs, in addition to between 700 and 950 full or part-time jobs resulting from the closure of six stores.

"We will be discussing our proposed realignment of our store network and operating model with impacted team members and the unions," Grayston said in statement to the market.

The six store closures were across the company's Noel Leeming, The Warehouse and Warehouse Stationery brands, and were in addition the three previously announced.

The proposals was to close Noel Leeming Henderson Clearance Centre, and Tokoroa store, The Warehouse Whangaparaoa, Johnsonsville and Dunedin Central stores and Warehouse Stationery Te Awamutu store.

He said the company had seen strong trading across its brands, following the move to alert level 2.

"This level of trading is seen largely as a consequence of pent up demand and is not expected to continue as the economic impacts of Covid-19 are realised," he said.

"Given the continued uncertainty around trading performance the Board reaffirms its position on withholding guidance on FY20 earnings."
