Planning is underway for the construction of an International Logistics Hub and Offshore Supply Base to support the oil industry in the southern part of New Zealand. This would allow for easy development into a major industrial cluster and logistics centre. 1 CBD Supply base area Engineering cluster Wharf area Key Features: A land area of more than 200,000m2 25 km from Dunedin International Airport It is fully serviced for all utilities 10 km from the associated deep water Port Chalmers Container Terminal 24 hours a day, seven days a week operation is a permitted activity Within the proposed area there is provision for a tank farm Commercial shipping of up to 8.0 metres draft and 32.2 Commercial terminal and Stevedore services metres beam catered for at the Dunedin wharf system Provision for bulk cargo, warehousing and storage facilities

  • COCKLES (COC 3) Otago Peninsula (Austrovenus Stutchburyi) Tuaki
    COCKLES (COC 3) COCKLES (COC 3) Otago Peninsula (Austrovenus stutchburyi) Tuaki Waitati Inlet Purakunui Otago Harbour Papanui Inlet 1. FISHERY SUMMARY COC 3 was introduced into the Quota Management System in October 2002 with a TAC of 1500 t; comprising of a customary allowance of 10 t, a recreational allowance of 10 t, an allowance for other fishing related mortality of 10 t, and a TACC of 1470 t. Historical catch limits can be seen in Table 1. 1.1 Commercial fisheries Cockles are present at various locations around the Otago Peninsula but are only commercially fished from Papanui Inlet, Waitati Inlet, and Otago Harbour (under a current special permit). Commercial fishing in Papanui and Waitati Inlets began in 1983. A limit of 104 t was in effect for Papanui and Waitati Inlets combined from 1986–87 until 1991–92. From 1992–93 to 1998–99, the catch limits were 90 t for Papanui Inlet and 252 t for Waitati Inlet. In April 2000, the catch limits were increased to 427 t for Papanui Inlet and 746 t for Waitati Inlet. In 2002 when cockles entered the QMS spatial restrictions upon harvest within COC 3 were removed. Commercial landings from Papanui and Waitati Inlets are shown in Table 1. Since August 2009 cockles have been taken from Otago Harbour under a special permit in order to investigate the ecosystem effects of commercial cockle harvesting in this location. This permit stated no explicit limit to the tonnage able to be taken buts delimited the area where harvest would be taken and expired on January 31st 2017.
