Through Project Crimson, a Department of Conservation initiative, the Dunedin school won 25 pohutukawa and rata trees to plant on site, principal Mike Darracott said.
The project aimed to raise awareness of tree protection and conservation.
Blueskin Nurseries provided plastic tags for the school's 90 pupils to write their names on and mark their trees.
They would be expected to trim grass around the trees, feed them and, if necessary, stake them.
Pupil Jack Tuwhangai-Herd said he was proud his school cared about the environment and "loved" the opportunity to plant native trees.
Teacher Anne Swan said the planting was one of many steps the school had taken over the past few years.
These included other tree plantings and establishing an edible garden.
