The City of Onkaparinga has announced the appointment of Sharon Mason as its new Chief Executive Officer, following an extensive recruitment process.
The council says Sharon brings a wealth of experience in local government leadership and health governance, combined with a strong track record of driving organisational transformation and delivering sustainable outcomes for communities.
She joins City of Onkaparinga from her current role as Chief Executive of Selwyn District Council, one of New Zealand’s fastest-growing territorial authorities.
In this role, she oversaw a $230 million operational budget, $3 billion in infrastructure assets, and a workforce of over 700. Her leadership delivered significant improvements in staff engagement, customer satisfaction, and infrastructure delivery, alongside the development of Selwyn’s intergenerational strategic vision.
Her previous experience includes serving as Chief Executive of Buller District Council, where she transformed the organisation into a high-performing council and secured major economic growth funding.
She has also held senior executive roles in health governance across New Zealand and Tasmania and began her career as a British Army officer in the Queen Alexandra Royal Army Nursing Corps—bringing a unique perspective on leadership, discipline, and service.
Deputy Mayor Michael Fisher has welcomed the appointment.
“Sharon’s proven ability to lead complex organisations through change and her commitment to collaboration and innovation make her an outstanding choice for our community. We look forward to working with her to deliver on our strategic priorities and create a thriving future for the City of Onkaparinga,” he says.
“The Council is confident that Sharon’s diverse experience and inclusive leadership style will help shape a strong, sustainable future for the region,” he said.
Ms Mason has expressed her enthusiasm for the role and her excitement about moving to the Onkaparinga region.
“I am thrilled to join the City of Onkaparinga and work alongside Mayor Moira Were, councillors, and the dedicated staff to deliver on the Community Vision 2034.
“This is an exciting opportunity to be part of a progressive and strategic council that places community at the heart of everything it does.
“I’m committed to fostering strong engagement with residents and stakeholders, ensuring that together we create sustainable outcomes for the region.
“I also look forward to working in partnership with First Nations people in the City of Onkaparinga to support the transition of the Reconciliation Action Plan from reflection to innovation.
“My family and I are looking forward to making Onkaparinga our home and building meaningful connections within this vibrant community,” she says.
