Mrs Harris (29), retired from the sport after the 2006 Winter Olympics to set up her own personal training business.
Now mother to 2-year-old Hugo and 8-month-old Tilly, Mrs Harris said her new job was a good fit with her career as a mum.
"[The job] is quite different from the sporting things, but I did a lot of my own fundraising while I was ski racing.
"It's been quite a steep learning curve over the last month or so ... [working with] the different branches in Dunedin, Southland, North Otago and Central Otago ... and trying to make as much money as we can."
Mrs Harris took up the position in February, ahead of the Child Cancer Appeal month, which is March.
This year, the foundation aims to raise $1 million to support families of children with cancer.
However, this year it was particularly difficult given recent events in Christchurch and Japan.
The foundation did not receive any government funding and all the money raised during the appeal month would go directly to the families in areas where the need was greatest.
"Right now, we've got families in Christchurch with cancer.
"They have been hit doubly hard. Their kids have got cancer and they're trying to deal with an earthquake.
"A lot travel to Christchurch for treatment, some have had to go home and interrupt their treatments.
"It's really tough fundraising at the moment, but we're still asking people to dig deep and support this."
Mrs Harris said the annual Beads of Courage collection would be held in Dunedin today and in Queenstown today and tomorrow.
Volunteers to help collect money were still needed.
"If people can do an hour or two hours it would be great.
"Two hours out of their day is not [much] and every single bit of that counts. Every hour spent collecting money makes life a little bit easier for families living with child cancer."
