Former American FBI special agent turned New Zealand DIY hardware chain boss John Hartmann is leaving Mitre 10.
Chairman Martin Dippie said Mr Hartmann was taking on the leadership of a firm in the United States so a search was on for his successor.
Hartmann had changed the business which pushed up sales 6.5 per cent annually to make $858.4 million in the June 2012 year, returning more than $45 million to members as a rebate, Dippie said.
The business had steadily invested in the co-operative with new stores in major centres and provincial towns, he said. Fifteen new Mega stores were opened.
"Under John's leadership, the company has put in place a highly qualified leadership team that has worked closely with the board on the strategic plan and annual business plans," Dippie said adding that the financial results were a clear indication of the team's ability to execute those plans.
Hartmann said it had been an honour and a privilege to work with the Mitre 10 owners, operators and associates of Mitre 10.
"The level of passion and dedication across the business is apparent and the culture is one that is clearly focused on satisfying the customers' needs."By Anne Gibson @Anne Gibson Email Anne
