Asked why he donated the food, Tonkin said it was simple.
"When I first found out about it, I did the normal human thing and ran straight to the supermarket to see what to grab. I got home and was having a beer and a ciggie and I thought, 'I don't actually need any of this'."
Tonkin said he looked up some community organisations and came across Family Works.
"I thought 'right, I'll go find a community service that can use it to benefit a family', and ended up knocking on the door here," Tonkin said.
"I've got everything I need. I don't need any more."
Family Works Whanganui manager Raewyn Anderson said she was thrilled with Tonkin's generosity.
"It's fantastic. We've got a lot of families struggling at the moment. To see this is really heartwarming."
Elizabeth, the recipient of one of the food parcels, said the support will go a long way to helping her get back on her feet.
"When you've had a year like we've had, and you've made that hard choice to make your life better, it isn't easy. You just do it and try and make a better life," the mother said.
"Having someone do something so kind just reminds you that there is still kindness out there."
