Kirsty Brennan from the Lyttelton Reserves Committee told 1News the free trees help spread the Christmas cheer.
Clearing the pest pines also benefits the environment as they make way for more native trees to be planted.
"What we've noticed is that the pine trees, the juveniles, they grow in clusters and so there must be some light getting to that area," Brennan told 1News.
"What we'll do in the next planting season is we'll put some natives in there and start expanding the native planting in the reserve."
