Tree Information x

Identifier: AR/0963
Tree Type: Single
Registered By: Smillie, M.J.
Registration Category: Notable tree – International interest
General Notes:
A fine specimen located near the old Brook Haven homestead, now part of Awhitu Regional Park. The tree has been referred to as the largest macrocarpa in New Zealand, and is the largest single-stemmed tree in the world. Many other trees quote as being larger are clearly multi-stemmed specimens. Another large NZ single-stemmed tree is located in Brooklands Park, New Plymouth - see TR/0763.

The Awhitu tree is located at the edge of a paddock close to the old homestead, approximately 60 metres from the harbour's edge. The homestead was built in 1878 by John and Sarah Brook, and it is likely the tree dates from around this time.

The land was sold to the Auckland Regional Council in 1971, and Awhitu Regional Park was subsequently opened in 1975.

Kevin Barker has been re-measuring the tree on a regular basis. The height and spread have not changed much, but girth increases by 10 to 12 cm per year, most recently measured at 15.3 m. (Smillie, 2024)
