Supporting Technical Assessments

82 Oct 2021 OceanaGold WNP Project, Waihi - Archaeological / Heritage Assessment possibility of additional subsurface remains in relation to past mining activities cannot be ruled out and would also be destroyed by the proposal. There are no known pre-European Maori sites within the NRS Pouhere Taonga Act 2014 with regards to archaeology. Archaeological survey, recording and investigation of any subsurface archaeological features uncovered during earthworks for the NRS and related infrastructure. The feasibility of this would need to be on a case by case basis. Positive effects for the NRS project Any information gained through archaeological investigation and recording of any subsurface archaeological features will potentially aid our understanding of the history of the area. General Mitigation of Heritage Effects It is recommended that the following historic heritage mitigation measures are adopted for the NRS project: • Include accidental discovery protocols, as a condition of resource consent, advising OGNZL of their obligations under the Heritage New Zealand Pouhere Taonga Act 2014 with regards to archaeology. Overall Effects The capping / infilling of the Queen of Waihi Shaft (T13/971) and the unlikely destruction of subsurface remains associated with early mining workings is a minor adverse effect but will not cause significant, unacceptable adverse impacts on historic heritage if appropriately mitigated through archaeological recording. Overall the effects on historic heritage after recommended mitigation are likely to be less than minor in relation to the proposed NRS.
