There will be homework tasks to complete about each country.
And some of the financial support they received will be donated to the Nga Manu Nature Reserve.
"We are teaching our moko it is great to give," Dot said.
While the focus is on the upcoming swimathon, various other fundraisers have been completed, including selling homemade lemon honey, gardening within the community, busking at a local market, hosting two pop-up restaurants, mowing lawns, a garage sale and selling a painting.
"We would just like to thank everybody who has supported us all the way through.
"The support has been amazing."
Dot said the children had learnt it took hard work to achieve goals.
"A question I asked the children at the onset and throughout was 'how hungry are you for this?
"Would you like an entree, just the main course, or only dessert, or are you starving?
"To sit and eat a feast takes hard work.
"The enjoyment is to savour every morsel of your hard work."
