History In the 1980s, the New Zealand Electricity Department (NZED) (a government department) controlled and operated almost all New Zealand electricity generation and operated the electricity transmission grid. The first phase of deregulation saw the New Zealand Government corporatisze the NZED and form the state-owned enterprise Electricity Corporation of New Zealand (ECNZ). In 1994 Mercury NZ Limited was formed by the Auckland Energy Consumer Trust to own and operate the electricity supply business previously operated by the community-owned local authority, Auckland Electric Power Board (AEPB). Also in 1994, Transpower New Zealand was separated from ECNZ and created as a State Owned Enterprise (SOE) to own and operate the national grid. In 1996, ECNZ split into two SOEs, ECNZ and Contact Energy. In 1998, law changes obligated AEPB to sell the electricity retailing and generation part of the business. On 1 April 1999, ECNZ was split into three – Genesis Energy, Meridian Energy and Mighty River Power. Mercury's electricity retailing division was sold to Mighty River Power, who continued the trading name Mercury
