About One Tree Hill / Maungakiekie
Maungakiekie was one of the largest and most heavily fortified pā sites in pre-European Tāmaki Makaurau. Visible terracing and earthworks on the slopes record centuries of occupation by iwi including Wai-o-hua and later Ngāti Whātua. The name refers to the kiekie vine that once grew on the maunga.
The original sacred tōtara on the summit was felled in the 19th century. A Monterey pine stood there for much of the 20th century until it was removed in 2000. In 2016 the Tūpuna Maunga Authority replanted native trees including tōtara and pōhutukawa on the tihi.
The obelisk at the summit honours Sir John Logan Campbell, who gifted the land for Cornwall Park. Campbell is buried at its base. The monument stands approximately 30.8 metres tall and was formally unveiled in 1948.
Cornwall Park operates under the Cornwall Park Trust Board and functions as a working farm with year-round sheep grazing. It also contains one of New Zealand’s oldest olive groves and Acacia Cottage, Auckland’s oldest surviving residential building, constructed in 1841.
Walking Tracks
Multiple tracks wind through Cornwall Park and up Maungakiekie. A new summit track connection completed in May 2026 provides a direct route from Cornwall Park with boardwalks, stairs and views of Rangitoto, Maungawhau and the Waitākere Ranges.
Tracks protect archaeological features while offering varied gradients suitable for different fitness levels. The council’s Maungakiekie / One Tree Hill Path, 3 km from 672 Manukau Road, takes about 50 minutes; allow longer to explore the park.
Playground and Family Facilities
One Tree Hill Domain features a well-maintained playground near the Manukau Road entrance. Facilities include slides, swings, a tall wooden climbing structure, a miniature red train ride and a nearby skate bowl. The area is popular with families and connects directly to walking paths and open grass for picnics.
