Abstract: This report presents the results of the geotechnical and the engineering geological assessment of Sector 3 of the proposed Huntly to Marsden Power Station gas pipeline. The proposed gas pipeline is a welded steel pipe, approximately 500 mm diameter and buried a minimum of 1 m below the ground surface. The investigation consisted of a detailed office study of existing information and field reconnaissance of the proposed route. The pipeline route in Sector 3 extends from Silverdale to Marsden Point, traversing the eastern side of the Northland Peninsula. Prepared for Electricity Corporation of New Zealand Limited. (auth/DG)
