Caralee McLiesh appointed as new Treasury secretary

The State Services Commission has announced the appointment of a new Treasury secretary to replace outgoing boss Gabriel Makhlouf.

Makhlouf, who is moving to Ireland to run its central bank, departs under controversy over his handling of the Budget 'hacking' scandal last month.

Australian Dr Caralee McLiesh will take his place as the leader of New Zealand's public finance system, State Services Commissioner Peter Hughes announced on Tuesday.

"This is a big and important role for New Zealand and the public service," Hughes says.

"I am delighted to appoint Dr McLiesh. She is a highly respected, world-class economist with very strong fiscal, economic policy and financial management credentials."

Dr McLiesh's experience includes education leadership, several deputy secretary roles at  the NSW Treasury, and work for the World Bank.

She was involved in developing Australia's first social impact bond, to help families at risk. She was awarded the Public Service Medal of Australia (2017) for outstanding public service to social impact investment policy and reform in NSW for her work.

"Dr McLiesh has more than 20 years' experience in the government, international, not-for-profit, and commercial sectors and has led large, complex reforms with multiple stakeholders to improve citizen outcomes," Hughes says.

"I have no doubt the public service and New Zealand will benefit from her skills and experience."

Dr McLiesh has been appointed for five years from September 16.
