What is Local Water Done Well? 

In December 2023 the Central Government announced a new direction for water services (drinking water, wastewater and stormwater services) called Local Water Done Well.   

Water reform in the greater Wellington metro area is a collaboration of five councils:

  • Hutt City 
  • Upper Hutt City
  • Porirua City
  • Wellington City
  • Greater Wellington

And two iwi groups:

  •  Ngāti Toa Rangatira
  • Taranaki Whānui ki Te Upoko o Te Ika 

Together we are developing a new multi-council-owned organisation that will take ownership of public drinking water and wastewater networks.

The Kaitoke Pipe Bridge Project is part of efforts to ensure a resilient connection for the region’s primary water supply, transporting water from Te Awa Kairangi | the Hutt River to Te Mārua Water Treatment Plant.

The new organisation, with the interim name Metro Water, is due to take over from Wellington Water Ltd on 1 July 2026. Water infrastructure will remain publicly owned and managed on behalf of ratepayers and the community.

What is the Water Services Delivery Plan?

The five councils have delivered a joint Water Services Delivery Plan - a road map for delivering safe, reliable and environmentally and financially sustainable water services.  

This plan has been provided to the Department of Internal Affairs as a requirement of the Government’s Local Water Done Well policy.

You can read an overview of the water services delivery plan below:

Greater Wellington's role 

Greater Wellington has a unique position, being the only regional council in Aotearoa New Zealand with a dual role in water services delivery.

It also has a unique role for a regional council in providing drinking water to city councils for them to distribute to houses and businesses (also called ‘bulk drinking water supply’).
