Nomination statement
Maungawhau / Mount Eden is a wāhi tapu and one of the most culturally, historically and visually significant ancestral maunga in Tāmaki Makaurau. With over one million visitors annually prior to COVID 19, years of unmanaged access had resulted in severe erosion, damage to archaeological features, and degradation of the mauri of the tihi (summit). Commissioned by the Tūpuna Maunga Authority, the Maungawhau Tihi Boardwalk project was conceived as a carefully considered, low impact landscape intervention capable of protecting and healing the maunga while maintaining public access and enhancing understanding of this sacred place. Delivered across two stages between 2020 and 2024, Stage 2 completes the boardwalk circuit around the crater rim and upper tihi, building on the proof of concept established in Stage 1. The project is grounded in Te Ao Māori values and guided by close partnership with mana whenua. The design employs a restrained and reversible “kit of parts” boardwalk system, lifting visitors above the ground plane to protect archaeological features, halt erosion, and allow the landscape to recover. Materials were selected for longevity, reversibility and visual recessiveness, ensuring the landform remains the dominant presence. The boardwalk choreographs a sequence of movement and pause, revealing layered views across the volcanic field, harbours and city while reinforcing Maungawhau’s role as both an ancestral landmark and shared civic space. Through light infrastructure, ecological restoration and cultural humility, the project demonstrates how landscape architecture can support regeneration, manaaki people, and restore the mana and wairua of a living ancestral landscape.
Judges' citation
Stage 2 of the Maungawhau Tihi Boardwalk is an exquisitely detailed and remarkably light-footed intervention within one of Tāmaki Makaurau’s most significant cultural landscapes. With quiet assurance, the structure traces a considered route around the volcanic cone, creating a connected sequence of paths and carefully positioned pause points from which visitors can appreciate the landform, wider urban landscape and the significance of the maunga itself.
Elevated above previously vulnerable ground, the boardwalk protects the cone from erosion from heavy foot traffic and unmanaged movement, while site-stability planting repairs disturbed areas. Historic terraces and pits remain undisturbed, and the walkway supports the landscape’s ongoing regeneration. Its refined palette and restrained detailing allow the structure to recede, honouring the maunga and ensuring that the cultural and natural qualities of the place remain pre-eminent.
Developed for the Tūpuna Maunga Authority by Isthmus, with engineering support from Stellar Projects and delivery by HEB Construction, the project builds on Stage 1 to complete the circuit around the cone, bringing cultural values, landscape architecture and engineering together with exceptional care. Stage 2 transforms the tihi from an open, loosely defined recreational space into a more intentional and respectful experience, one that guides movement, protects wāhi tapu and the volcanic form, and fosters a deeper connection with the natural environment. The result is an exemplary expression of design restraint, restoring the mana and mauri of Maungawhau while enabling people to encounter this ancestral landscape with clarity, care and respect.
