Distribution of electricity from the grid exit points to the end consumers' premises is the responsibility of about 30 distributors, also known as lines companies, who have monopoly control of the lines services on their networks. Ownership of distributors is through trust-owned companies, such as Auckland Energy Consumer Trust, and public companies. Some major industrial users are directly connected to the grid, such as New Zealand Steel and the Tiwai Point Aluminium Smelter.
