The Warehouse founder Sir Stephen Tindall is taking a year off to focus on other work, including Team New Zealand's preparations to defend the America's Cup.
The year's leave of absence marks the retailer's 35th anniversary in business.
Tindall is taking leave because of the workload required from other commitments, including as chair of Team New Zealand, and venture capital work with his company K1W1.
The leave is his first period of long leave since he founded the firm in 1982.
Tindall said reducing the workload at The Warehouse would enable him to focus on other commitments - in particular, securing the necessary infrastructure in Auckland to host a defence of the America's Cup.
