In the 19th century Te Ahumairangi (Tinakori Hill) was cleared of native forest and converted to pasture. During the depression of the 1930s, the eastern side of the hill was planted in radiata pine and other exotic species to provide work for the unemployed. But in 2004, many of these trees were toppled by a storm. After the debris was cleared, the area was planted with northern rātā. Storms in 2013 felled more trees.
