Alatana said the school organised the students' visits and several had kept going, realising family may be unable to.
Last term, with Year 6 students Nathan Ballissie and Seni Iasona, Alatana raised money for the dementia unit because they wanted to see residents happier and having more to do.
"One day we were at Kandahar reading, and we asked one of the ladies what do you do around here for fun?"
When Alatana heard they walked, sat in the garden and played bowls, she thought of what pupils did for fun: "We make art, play around and draw on iPads. We couldn't buy them iPads, but we wanted them to do art and crafts."
The team raised $144.75 by holding sausage sizzles and bought a cuttlebug machine used for craft activities.
Alatana was nominated by office manager Lynne McCartney, who told organisers of her "genuine compassion, kindness and empathy towards our older generation".
