Three Waters Reform

The Government is considering how best to regulate and deliver the three waters - drinking water, wastewater and stormwater services - across New Zealand.

At the moment 67 different councils, including Porirua, own and operate the majority of the country’s water services. However, councils face a number of challenges to deliver these in an affordable way into the future, including ageing infrastructure, growth and the impacts of climate change.

The Government’s reform proposes putting all water services into four larger public entities. Porirua would be in entity C with 22 other councils from the top of the South Island, the Wellington region and the east coast of the North Island.

This is a big issue for all Councils and one we are taking very seriously to ensure a good outcome for Porirua. It is clear things cannot continue as they are, but the way forward has not been decided yet.

Changes will not come into place until 2024 and in the meantime, we will continue to deliver water services through Wellington Water, the region’s joint Council controlled organisation. Porirua, Wellington, Hutt, Upper Hutt, Greater Wellington and South Wairarapa Councils are all owners in Wellington Water

It’s early days and there is a lot to work though. We will keep this page updated as things evolve, and there is extensive information on the Department of Internal Affairs’ website and on the Local Government New Zealand website.

  • In 2016, Havelock North's water became contaminated and many people in the township fell ill, with a number of deaths. This sparked the Government to examine the regulatory and delivery environment for "three waters" services (drinking water, wastewater and stormwater).
  • The government subsequently established Taumata Arowai, a new water services regulator, to administer and enforce a new drinking water regulatory system. Once Taumata Arowai is fully functional, it will oversee and administer an expanded and strengthened drinking water regulatory system and oversee the environmental performance of wastewater and stormwater networks.
  • The Government has also looked at the way water services are delivered across the country (around 85% of the country has drinking water delivered by Councils. The rest are on private supplies).
  • Through this process, the Government commissioned a analysis from Water Industry Commission for Scotland (WICS) which estimates New Zealand would need to invest between $120 billion to $185 billion in its three waters infrastructure over the next 30 years to meet drinking water and environmental standards and provide for future population growth.

  • Last year, Porirua City Council (along with every other Council in the country) signed a Memorandum of Understanding (MOU), agreeing to work with the Government on water reform. That didn’t require Porirua city to agree to opt into the reform.
  • In exchange, we received what the Government has called fiscal stimulus money. In our case this was $59m for our region. This money went into our water services (mainly renewals of our pipes). There is a requirement to spend this stimulus by 30 March next year.
  • Since the latest round of announcements (in July), the Government has given Councils until the end of September to analyse the WICS data and information provided by the DIA and consider the implications for the Council, the city and the people who live and work here. No decisions are required. Following feedback from councils, we then expect the Government will make decisions on its next steps in the process.

  • We are working through the extensive information provided by the Department of Internal Affairs (DIA) to better understand how the proposals would affect the Council and the community. Through this process we will also consider alternatives to the proposals and identify issues of local concern to allow the Government to consider ways of addressing these.
  • Under the Government's proposal, Porirua would be part of "Entity C" along with 22 other councils from the top of the South Island, the Wellington region and the east coast of the North Island.
  • The proposal indicates the entities would have an independent board which would deliver the needs of Councils through a yet-to-be finalised governance structure. Councils would not hold a financial shareholding interest in these new entities.
  • The assets (including pipes, pump stations and the wastewater treatment plant) would be transferred to the new entity who would be the new owner of these assets.
  • The costs of water services that are currently paid by everyone in their rates will be removed and billed separately by the water entity - just as you receive a bill for electricity supply.
  • It is intended that the entities have the scale, capacity and capability to improve delivery at an affordable cost. The proposals also mention a suite of mechanisms to protect Māori/iwi rights and interests and prevent privatisation, and an economic regulator would be appointed to protect consumer interests and provide strong incentives for performance.
