A cliff-backed coastal reserve where 1.75 million years of volcanic geology, a living endemic plant, a marine protected area, and active iwi co-management converge in one place.
Back Beach is not a classic sandy dune beach. It is a cliff-backed coastal reserve where the standard DCI transect must be adapted — and that adaptation is itself a valuable learning exercise. The cliffs expose a readable geological record spanning 1.75 million years. The beach is dark volcanic sand. And directly offshore, the Sugar Loaf Islands form one of New Zealand's most accessible marine protected areas.
The reserve is managed under a 2023 Integrated Co-Management Plan between NPDC, DOC, Ngā Mahanga a Tairi, and Ngāti Te Whiti — making it one of the few sites in Taranaki where students can see kaitiakitanga operating as a formal, legal framework alongside scientific monitoring.
The Herekawe Stream discharges directly onto the beach and is subject to TRC resource consent monitoring due to stormwater inputs from the adjacent Omata Tank Farm. This connects the DCI's "buffering" and "water quality" indicators to a real, active regulatory process.
