Supporting Technical Assessments

WSP 1 1 INTRODUCTION OceanaGold New Zealand Limited (OceanaGold) propose the expansion of the Waihi Gold Mine, known as the Waihi North Project (WNP). This project will extend the life of mining in Waihi to 2038 and consists of the following main components: — Wharekirauponga Underground Mine: a new underground mine 10km north of Waihi and associated surface infrastructure to support this activity located on land at the end of Willows Road, approximately 5km north of Waihi. — Gladstone Open Pit: mining of a new open pit located south of the existing Waihi operations, which on completion of mining will be converted to a tailings storage facility. — Tailings Storage Facility 3 (TSF3): increasing existing tailings storage through the construction of a third tailings storage facility (TSF3). — Northern Rock Stack: a new rock stockpile facility to the north of the current tailing storage facilities — Water Treatment Plant (WTP) upgrade: to double the current treatment capacity of the existing WTP. — Processing Plant Upgrade: increased throughput capacity at OceanaGold’s existing Processing Plant. WSP New Zealand Limited (WSP) has been appointed to undertake an independent Social Impact Assessment (SIA) to inform the Resource Management Act, 1991 resource consent requirements. The purpose of the SIA is to identify and fully consider the potential positive and negative impacts of the proposed WNP on the local and regional social environment. The development of an understanding of the social context in which the proposed project will take place, through the collection and analysis of baseline data, is an important component of the SIA study. The following document is the baseline assessment of various measurable attributes that will be used to inform the SIA study. It is most likely that some of these attributes will be identified as relevant for future assessment in respect of monitoring the social impacts of the WNP on the Waihi Town and greater local area. This baseline covers the following attributes over a defined area of interest: — Demographics — Economics — Employment — Property — Community Infrastructure
