Utilities of New Zealand
The Electricity Authority oversees the liberalised electricity market, with the national grid remaining in state hands under Transpower. The electricity sector was opened to competition in the late 1980s, with some electricity suppliers remaining state owned, such as Genesis Energy, and others being privately owned.
New Zealand’s water supply system is managed by Territorial Local Authorities, which are public-sector organisations. They are also responsible for trunk sewerages and sewage treatment. There is little private sector involvement.
