Doc last week confirmed Nicola Holmes would leave the role in "mid-July".
A spokeswoman said the recruitment process for a replacement had not yet started.
Doc’s careers page had 27 jobs listed yesterday afternoon, mostly for roles based in Auckland, Wellington and Christchurch and none in Otago.
Last week, Doc announced it would be disestablishing 257 permanent positions and creating 133 new ones in order to find 6.5% of savings from its budget and meet the government’s savings targets.
In a statement, Doc said it would work to transfer staff into the new roles where possible and aimed to implement the changes by July 1.
Mrs Holmes, a former detective in the British Army, took up the operations manager role in 2021.
Shortly after starting the Doc job, she told the Otago Daily Times the opportunity to work for Doc while based in Wānaka was "blimmin’ marvellous".
"Everyone is passionate about conservation ... They’ve got this values-based link, whether they work in IT in Wellington or are a hut warden. Everyone connects."
She was unavailable for comment last week.
