CGE is a Western Australian organisation aimed at promoting gender equity.
It currently has 37 WA CEO members, including Kerr, Independence Group's Peter Bradford, Fortescue Metals Group's Elizabeth Gaines, BHP Iron Ore asset president Edgar Basto, KPMG WA chairman Gary Smith, Alcoa Australia's Michael Parker, Deloitte managing partner Michael McNulty, and CME chief Paul Everingham.
Kerr said it was his belief that success relied on having a team made up of the best people with broad perspectives and experiences.
"The benefits that result from a diverse workforce, and gender equity in particular, are largely about the diversity of thought and experience that these differences bring," he said.
"Creating a workforce that is as vibrant and diverse as the demographics of the countries and communities where we operate and live, contributes to a high performing and inclusive culture."
Kerr said it was his role as a leader to drive the required changes from the top.
"I will champion a culture of inclusion to ensure we create diverse teams to bring different perspectives and we focus on accessing the complete talent pool in the communities where we operate," he said.
"I have put in place measurable objectives to ensure more balanced gender representations at all levels of our organisation and I will actively track our progress."
The CGE team has also recently moved into South32's Perth head office after Kerr offered them office space.
CGE is aiming to get 125 CEO members by 2021.
