The Wattie's Cans Film Festival helps provide food cans to the Salvation Army to stock up its foodbanks and help those in need during the busy Christmas period.
From 29 October, New Zealanders can head to their local participating movie theatre and start swapping their cans of food for movie tickets ahead of the event on November 7.
Wattie's then matches each can donation with a can of its own.
Moviegoers need to get in early, as tickets often sell out in advance.
Salvation Army Secretary for Social Services Major Pam Waugh said without the Wattie's Cans Film Festival, the service would struggle to keep up with the need for food parcels at Christmas.
"What better way to help out? For the price of a can of food people can see a movie and feel good about it,'' she said.
A list of participating cinemas is set to be announced later this month.
