OceanaGold | Waihi North Project | Recreation and tourism assessment 33 although operational noise would be clearly audible, noise levels would be only just above what would occur without the project in place. Landscape: Boffa Miskell (2022b) note that intervening vegetation covers the majority of Ngāti Koi Domain and limits the areas from which views out towards GOP are available from the top. Where visible at lower elevations, GOP will extend a local area of mining activity seen in association with the existing Processing Plant and Favona Portal. At completion, the potential for adverse effects will be remedied as rural land use is re-established in this context. Similarly for the NRS any change in view will remain in the context of the existing mining activity and surrounding rounded hills to represent no detrimental reduction in visual amenity. Boffa Miskell (2022b) also note that views are similarly concealed by vegetation within Union Hill, with no existing recreation tracks currently formed on the eastern slopes in the direction of Gladstone Hill. Vibration: Heilig & Partners Pty Ltd (2022) consider the effects of blasting and subsequent vibration, overpressure and flyrock effects from the GOP. Figure 21 shows the potential flyrock zone around the GOP, which includes public tracks leading to and within Ngāti Koi Domain, and beside the Ohinemuri River. During blast events, closure of these tracks will be required for public safety, as was the case with the Martha Pit Rim Walkway during past blasting activity there. The duration and frequency of necessary temporary closures has not yet been determined, but are expected to be short in duration, and to not occur on Sundays as per the proposed consent conditions. The required Vibration Management Plan will establish trail closure protocols in agreement with the landowner (Hauraki District Council).
