GHD | Oceana Gold (New Zealand) Ltd | 12552081 | Waihi North 12 . – TSF2 is consented to 1,160.7 mRL. The current TSF2 stage has been rehabilitated to 1,156 mRL. The final crest raise and final rehabilitation timing is yet to be determined, being based on conclusion of mining activities and any requirements for potential future tailings disposal. TSF3 and the existing TSFs will receive tailings generated in the processing of ore from Gladstone, MUG, MOP4 and the WUG. Similarly, the NRS may store rock from Gladstone, MOP4 and the WUG. A water management report prepared by GHD (2022a) as part of the WNP assesses the cumulative effects of the both the existing mine activities and the proposed WNP on the Ohinemuri River (refer to Table 1.1).
