Structures is a point dataset representing Transpower owned high voltage transmission structures. Construction types include; poles, towers (pylons), gantries and termination points. The location of each structure is the ground centre point of the structure. The structures dataset is updated ad-hocly. (Caveat - not all structures comprising New Zealand's...

Transpower NZ Transmission Line Spans. This includes all overhead transmission lines. It is representational only of the centerline between each tower, pole or termination. Transpower owns and operates the National Grid - the high voltage transmission network connecting areas of generation with towns and cities across New Zealand. The National Grid is...

Transpower sites which include AC stations, DC Stations and Tees. Transpower owns and operates the National Grid - the high voltage transmission network connecting areas of generation with towns and cities across New Zealand. The National Grid is made up of over 12,000 km of transmission lines and more than 170 substations. Electricity is transmitted over...

Transmission Lines is a polyline dataset representing the power lines that are used to transmit electric power across NZ, usually from a power generating station to main substations that make up the National Grid. They are comprised of overhead and underground conducting lines of either copper or aluminium. In NZ these High Voltage (HV) transmission lines...

The Cook Strait Cable Protection Zone (CPZ) protects vital submarine electricity and telecommunication cable links between the North and South Islands. The protected HVDC power cables between Fighting Bay in the South Island and Oteranga Bay in the North Island are part of the High Voltage Direct Current (HVDC) cables that transmit power between Benmore...
