Between 1984 and 1994, 250,000 - 300,000 trees were planted by volunteers.  The island is now 60% re-vegetated, the other 40% being left as grassland for such species as takahe , for views and to protect archaeological remains.

The trees planted were, in most cases, raised on Tiritiri Matangi from seeds collected on the island or nearby so as to maintain genetic purity.

The wattle trees in Wattle Valley were encouraged as they provide shade for seedlings and are also an excellent source of food in winter for such species as the honeyeaters.

A number of plants, not originally believed to have existed on Tiritiri Matangi, have been introduced because of their scientific importance (eg New Zealand Bignonia (Tecomanthe speciosa) and Kaka Beak (Clianthus puniceus).
