The tallest known tree in New Zealand is an Australian mountain ash (Eucalyptus regnans), recently measured at 80.5 metres. It is one of a stand of tall trees of this species Orokonui Ecosanctuary in Waitati just north of Dunedin.

Address: 600 Blueskin Road, Dunedin 9081, New Zealand Dunedin & Otago


Located just 20 km north of Dunedin City, the Orokonui Ecosanctuary comprises over 300 hectares of land, where the Otago Natural History Trust is restoring a New Zealand forest ecosystem in which native flora and fauna will thrive.
"The Rotary Club of Dunedin has generously sponsored the upgrade of the Saddleback Valley Track, which leads visitors to the tree.

The track follows Orokonui Stream, descending steadily and passing through beautiful podocarp forest and regenerating kanuka/broadleaf forest before reaching the extraordinary grove of eucalypts. The walk takes two to three hours return from the visitor centre."
