Leadership Team

Tracey-Leigh Peters, CEO

Tunumafono Tracey-Leigh Peters has a background in education and human resources. She began her career at Iosis in 2008, as Executive Administrator. She became Operations Manager in 2013, and was Acting CEO for 10 months before her official appointment as CEO on 1 September 2015. Tunumafono is a matai (chiefly) title from her Samoan family line.

To give a voice to our most vulnerable and give them the opportunity to make the changes needed to have a good family life is the heartbeat of what we do. To see that transformation happen through the support that we can give is priceless.
