We have outlined the effects management for each component of WNP, but we note that the effects management is realised for the project as a whole and integrated accordingly. In this section we collect and summarise all of the effects management for the project, and in the following section (section 23) we outline the additional positive enhancements proposed for WNP. 22.2 Stream reclamation and diversions 22.2.1 Loss of watercourses The impact on some watercourses within the footprint of works is unavoidable. The quantum of stream loss resulting from WNP at Willows Farm and at Waihi is summarised in Table 47. A total of 3,944 m length of stream will be lost or diverted. Application of the effects management hierarchy means that: • There shall be no net loss of freshwater ecological function. • There will be no permanent loss of extent (length) of streams. • A combination of ecologically functioning diversion channels and existing stream channel restoration are to be undertaken as offset for the temporary loss of stream habitat.
