Dorothy Brown's Cinema and Bar announced on Friday it would present director Gerard Smyth's feature length and intimate documentary about the Garden City disaster at 6.30pm.
Manager Samantha Relph said, as the festive season approached, "We thought it might be an opportunity to remember the people of Christchurch and I have been in touch with the Salvation Army for advice on how best we can help."
"We are inviting people booking for Monday's screening to bring along a present for boys and girls aged 11 to 15. The gift should be unused and can be wrapped and labelled indicating the gender and age for whom it is suitable."
Miss Relph said Dorothy Brown's will reduce the ticket price for the screening to $12.50 as a thank you.
Community worker Blair McKenzie will attend to collect the gifts on behalf of the Salvation Army.
The documentary will be screened in the boutique cinema intermittently over the next few weeks.
"We are pleased to be screening this important documentary about Cantabrians, made by Cantabrians, and hope that the gifts received will be a reminder of our continued support to the people of Christchurch," Miss Relph said.
