The Green Party hopes that this bill delivers on its purpose of ensuring that drinking-water suppliers provide people and communities with safe drinking water and that they protect the sources of drinking water. Taumata Arowai was established as the water services regulator through new legislation last year, which set out the objectives, functions, operating principles, and its governance arrangements. It's got an external board. It's got a Māori advisory group to give advice on how to best enable mātauranga Māori, tikanga Māori, and kaitiakitanga to be exercised, and this bill sets out the regulatory regime that Taumata Arowai will administer, its specific responsibilities and powers, and the duties of drinking-water suppliers and local authorities.
