A 4.9 Mkm2 region of the southwest Pacific Ocean is made up of continental crust. The region has elevated bathymetry relative to surrounding oceanic crust, diverse and silica-rich rocks, and relatively thick and low-velocity crustal structure. Its isolation from Australia and large area support its definition as a continent—Zealandia. Zealandia was formerly part of Gondwana. Today it is 94% submerged, mainly as a result of widespread Late Cretaceous crustal thinning preceding supercontinent breakup and consequent isostatic balance. The identification of Zealandia as a geological continent, rather than a collection of continental islands, fragments, and slices, more correctly represents the geology of this part of Earth. Zealandia provides a fresh context in which to investigate processes of continental rifting, thinning, and breakup.
The North Otago region of the South Island of New Zealand is well known for its volcanic deposits, including, the Boatmans Harbour Pillow Lava and the Kakanui Mineral Breccia which have had notable interest from geologists since the late 1800’s.

Abstract: The Waitaki Whitestone Geopark aspires to be New Zealand’s first UNESCO Global Geopark. Many Geoparks around the world include ‘geotrails’ that integrate the different attractions and activities in an area. The proposed Waitaki Whitestone Geopark has been focusing on establishing a ‘Geogastronomy trail’ that will invite visitors to engage with the Geopark through experiencing its food and drink. This research sought to explore the perspectives of stakeholders on the proposed Geopark and its associated geogastronomy trail. This document primarily reports on the data collected through 17 interviews with 20 representatives of the Waitaki geogastronomy sector.
