A fundraising night and silent auction where the pair sold babysitting, ironing and other odd jobs started the ball rolling, and was soon followed by a fundraiseonline.co.nz page.
Koru Care Charitable Trust is a voluntary organisation that aims to bring joy to children who face daily struggles by taking them on trips to California and Australia's Gold Coast.
Chairwoman Ann Bain said this year's trip was the 30th, meaning more than 800 children have had the experience because of the support and generosity of the public.
"Our sole focus is to give these children a much deserved opportunity to put their everyday difficulties behind them and to be regular kids for two weeks," she said.
"Grace has had major operations and stuff since when she was a baby," said Molly, "and I have had smaller issues but they are still issues. We are the only friends we know with stuff like this, so it's hard for us to be able to meet other kids who have gone through what we have gone through."
