"The puriri trees are impressive, with some more than 1.6m tall and boasting trunks bigger than the old 50 cent coins," land management officer Ben Banks said.
"The tanekaha trees have been the slowest to take off, but this was expected, with most nurseries reporting that they are one of the more difficult species to establish."
Over the next three years the project will focus on ensuring the kikuyu grass doesn't smother any of the smaller trees, and on encouraging the trees to grow tall and straight.
"It is exciting to see the trees' growth rates," Mr Banks said.
"Hopefully people will see that our native trees are an option as an alternative land use."
