OceanaGold Waihi general manager Bernie O'Leary has resigned from the company, effective from September 9.
O'Leary says the company is in a strong position.
"I leave knowing that the Waihi operation is in good hands. We have a strong and capable management team, well versed in what it means to successfully operate here, backed up by an equally strong corporate team.
"Together they will work with health safety and environment manager Dan Calderwood who will take on the role of acting general manager until Matt Hine, our new GM, arrives in early January."
Matt Hine is currently general manager at OceanaGold's Macraes operation in Otago, a position Bernie O'Leary held before coming to Waihi.
