Te Pūkenga's chief executive Peter Winder is leaving the organisation as the Government begins the process of disestablishing it.
It was set up by the previous Government as a merger of the country's 16 institutes of technology and polytechnics as well as industry training and apprenticeship groups.
But the new Government made disestablishing the organisation part of its 100-day plan, arguing it didn't want a centralised organisations for vocational education and training in New Zealand.
An email from deputy chair Sue McCormack provided to Newshub and sent to staff on Monday afternoon confirmed Winder would be leaving.
"The function and duties of the role that Peter was employed to perform will change significantly given the new direction of the organisation announced by the new Government," the email said.
"Accordingly, Peter and the Council have agreed that his role will come to an end by reason of redundancy in accordance with his employment agreement. Peter has agreed to continue in a transition role to assist the Council and its Committees until the end of January 2024."
The email said Winder had made a "significant contribution" over the past 18 months.
Deputy chief executive academic centre and learning systems Megan Gibbons has also resigned "to embark on a new chapter".
"I know it has been a big, and often challenging year for you all. I want you to know that we value your dedication and commitment, and the work you do every day to support our ākonga realise their full potential. Thank you."
In a statement earlier this month, Tertiary Education and Skills Minister Penny Simmonds said she had told the council of Te Pūkenga to cease any activities inconsistent with disestablishment, including recrutiment or staff restructuring.
"I have asked my officials for advice on the programme of work required to support the Government’s new agenda, including the legislative timeline.
"Key parts of that advice will include ensuring financial stability now, and in the future, and restoring regional decision making for local institutions to ensure they can better respond to the education needs of their communities.
"I will also be asking for advice on what other changes to the vocational sector might be needed to support and complement the disestablishment of Te Pūkenga."
