"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."
"I haven't been in New Zealand for nearly 20 years, and I'm looking forward to being back in New Zealand, being home and being with the family," she said.
