The Peters have been helped through Jamie's ordeal by Auckland-based charity Kidney Kids.
The charity has provided financial, emotional and physical support to the family, but a lack of resources has until now limited the amount of support Kidney Kids could provide the Peters and families like them.
However, thanks to the gift of a car by the New Zealand Toy Distributors Association, Kidney Kids' support staff will now be able to travel the country to offer support to people like Mr Peters.
Courtanay Gray from Kidney Kids national support said the new car was a major boost to the charity.
"It's huge. It means we can actually go to families instead of just calling them."
Despite having had the car for less than a month, Ms Gray had already been to Tauranga and Whakatane to visit patients and their families. The charity planned to visit all the major cities in New Zealand next year.
