Abstract

Seismic vulnerability is a major threat to New Zealand's winery industry. Many studies have assessed the vulnerability of New Zealand wineries, especially in high seismic regions. However, few studies have been conducted to assess the earthquake susceptibility of wineries in low seismic regions, such as Auckland. This study investigated the earthquake vulnerability of wineries in the Auckland region by (i) creating an inventory of the elements at risk in the wineries and (ii) assessing the level of vulnerability of these elements. As case studies, twenty-one wineries from various parts of the Auckland region were chosen. The research findings identified key elements at risk of seismic hazard in Auckland wineries using a field survey, including buildings, storage tanks, catwalks, and barrel racks. Furthermore, the findings revealed that at-risk elements are vulnerable to moderate to high levels, emphasising the need for resilience strategies to reduce potential earthquake losses. This study concluded that low seismic risk does not imply low vulnerability and that Auckland winery owners should reconsider their views on seismic risk mitigation. The study's findings benefit both winery owners and industry professionals by providing insights into the Auckland winery's vulnerability level and recommending approaches to improving the winery's organisational resilience.
