Stantec // Oceana Gold NZ Ltd // Waihi North Project Transportation Assessment 39 Hauraki District Plan Section 5.1 Rural Zone Rural Permitted Activity Performance Standard Comments network, especially the regionally significant roading infrastructure. Effects on Willows Road, Baxter Road and points of access to state highway network have been assessed herein. 9 Summary and Conclusion The current Waihi life of mine plan, authorised by existing consents including Project Martha, ceases production at the end of 2030. The Waihi North Project (WNP), as proposed by OGNZL, seeks to extend the life of the mine operation through to 2038 with rehabilitation in ensuing years. The WNP includes a new underground mine (WUG) to be located on farmland at Willows Road and with underground access to the existing Processing Plant at Waihi; a new open pit (GOP) near the existing Processing Plant; and the upgrading of Processing Plant and associated facilities. WNP will operate concurrently with the existing consented operations including Project Martha including the Martha Underground, Rex Underground and the MOP4. Traffic movements generated by the activity have been assessed based on a proposed work schedule for the period 2023 to 2039. The effects of development traffic on the local roads and their points of access to the arterial state highway network have been examined and recommendations have been made to mitigate any potential adverse effects including: • Upgrade of section of Willows Road and its intersection with SH25. • At Baxter Road access, ensure the day shift time associated with construction workers is well dispersed. • Monitor the workforce travel patterns and associated effect on the adjacent road network and adapt management of traffic to suit, where identified as required. • Provide adequate parking within the site(s). • Prepare and implement a PTMP. In summary, based on the recommendations and associated mitigation measures described herein, it is assessed that the potential adverse transportation-related effects of vehicular access and traffic movement associated with the project, during construction and over the longer term, will be avoided or mitigated to an acceptable level.
