Dr Aumua joins the Foundation in January 2021 from The Pacific Community's Suva office, where she has been Deputy Director-General.
"The reputation of the Foundation [Fred Hollows] is of course incredibly well known throughout the Pacific and New Zealand, and they are a fabulous organisation and do fantastic work," she said.
"I haven't been in a sector like this before, and I'm looking forward to what I might learn and also being part of the charitable community of the region, and of course New Zealand."
