Ms Hadley said an important part of the role would be engaging with the local community and building relationships.
"I’ve never been afraid to ask important questions and get things moving. My time in local and unitary government has taught me that everything starts with getting to know one another and focusing on shared visions."
She applauded the group for everything it was doing to support the community.
"I’m excited to be part of that, making a real difference at a grassroots level. We’re entering interesting and challenging times for the future of water across New Zealand and I hope to play my part in that conversation with the MCG."
Group co-chairwoman Anna Gillespie said the recruitment process for the position was extensive.
"We’re thrilled to have Clare join us, bringing her significant experience and mana to the role. We’re confident she will excel in the challenges ahead."
Group co-chairman Andrew Paterson said the group’s vision was for a thriving community united in creating a sustainable, healthy and balanced environment.
The group would fulfil its vision by leading through example, being action-orientated, and collaborating closely with the community and partners.
"Clare will be a driving force to help us achieve our vision and will serve as an important central point of contact."
Ms Hadley has spent the past 15 years in three chief executive roles at Rangitikei District Council, Nelson City and Invercargill city councils.
