This year people had mainly got test pots to help with house colour schemes or for art projects.
Major Paul Jarvis, of The Salvation Army's Whanganui Corps, said the campaign made a big difference to the community.
"It gives us a real boost, especially heading towards winter," Jarvis said.
"We will use some of the cans to help with transitioning people into housing and we're working in conjunction with the City Mission. This is a boost for the City Mission food bank."
Jarvis said the campaign was also a significant contribution by Resene, with the test pots normally costing $4.60 or $5.60 each.
There had been a steady increase in the number of Whanganui people needing food parcels, he said.
In 2018, The Salvation Army provided more than 60,000 food parcels to people throughout New Zealand who were struggling to put food on the table.
