...minimum flow by 10% and establish a unique minimum flow cut-off for Waka Kotahi. As explained, in my opinion, such an approach is complicated and problematic. However, to avoid effectively addressing any small environmental effects twice when regulating Waka Kotahi, once by the raised minimum flow and again by the reduced rate of abstraction, the potential abstraction by Waka Kotahi would then need to increase from the proposed 9% to 10% of the flow. 58. When deciding the ‘bes...
