The grid is owned, operated and maintained by Transpower New Zealand, a state-owned enterprise, although some lines are owned by local distribution companies and leased to Transpower. In total, the national grid contains 11,803 kilometres (7,334 mi) of high-voltage lines and 178 substations.Much of New Zealand’s electricity generation is hydroelectric, the majority of which is from power stations on lakes and rivers in the lower half of the South Island, while most of the electricity demand is in the North Island, in particular, the Auckland region. Consequently, large amounts of electricity need to be transmitted long distances from power stations to electricity users, including transmission across Cook Strait through the HVDC Inter-Island link. Investments in new transmission are regulated by the Electricity Commission and the Commerce Commission.In a news release in January 2012, the Commerce Commission reported that Transpower was planning to invest $5 billion over the next 10 years in upgrades of critical infrastructure.

At Oteranga Bay, the HVDC line converts back to overhead lines to cover the last 35 km, with the line terminating and connecting to the North Island's 220 kV grid atin . The main reason for a power system connection between the two islands is due to New Zealand's geography and demographics. The South Island has a large number of rivers suitable for hydroelectricity generation, however 75% of New Zealand's population lives in the North Island. HVDC was chosen for the inter-island connection because it is a more practical and economical solution for long distance transmission, particularly where significant lengths of cable are required.
