Trans-Tasman Resources Ltd | Draft Recreation and Tourism AEE October 2013 2 Rob Greenaway & Associates 1 Introduction and executive summary Trans-Tasman Resources Ltd (TTR) is proposing an iron sand mining operation in the coastal and offshore South Taranaki Bight area as shown in Figure 1. This report identifies the recreation and tourism activities which occur in the area that is potentially affected by this activity, defined as the coastal and offshore area extending 25 nautical miles (nm) (46.4 km) out to sea from mean high water springs (MHWS), between Hawera and Whanganui. Ohawe Beach has been defined as the northern-most extent of the ‘study area’ for recreation and tourism purposes. Figure 1: Study area Hawera Key Mining activity area Study area 25 nm Patea Whanganui The regionally important coastal marine recreation settings in the study area are based at the main public access and activity points: Ohawe Beach, Waihi Beach, the mouths of the Tangahoe and Manawapou Rivers, Patea, Waipipi, Waiinu, Kai Iwi and Castlecliff, and the fishing and cray-fishing resource up to 20 km offshore. The level of shellfish gathering along the coast is unclear but is a locally important activity. The section of coast extending from Patea north to Cape Egmont is relatively lightly fished in comparison with the coast south of Patea and in North Taranaki. Very little recreational fishing occurs more than 20 km offshore along the entire west coast of the North Island. Tourism activity in the study area is largely limited to the six beach camp sites and three fishing charter operations – two operating from Patea and one from Whanganui. Trans-Tasman Resources Ltd | Draft Recreation and Tourism AEE October 2013 3 Rob Greenaway & Associates Potential effects of the sand mining proposal of interest to the recreation and tourism community are, as identified from concerns expressed at public meetings and interviewees contacted for this report, and review of technical data prepared for TTR: . Turbidity effects (underwater visibility and smothering of biota) and the location of the sediment plume and sediment effects on onshore and offshore reef systems. Resuspension of returned sand during storm events or other wave action and the potential for long-term turbidity issues, . Recolonisation rates for biota in the mined area, . Toxicity of returned sand and effects on biota throughout the study area, . Changes to coastal wave patterns affecting surfing opportunities, . ‘Sand budget’ effects on the replenishment of beaches and sand bars (also an issue for surfing), . Exclusive use of the marine area in the mining area and interference with navigation routes for recreation craft, and . Effects on the environmental (‘clean green’) reputation of NZ. Review of relevant technical reports indicates the following potential scales of effect: Potential adverse effect on recreation and tourism due to changes to water clarity are:
