From 1 July 2025, IAWAI – Flowing Waters will be officially incorporated. Over the next 12 months, both councils will transfer the responsibility to build, manage and maintain drinking water and waste water services to the company.
Stormwater services will be provided to each council under a contract to IAWAI – Flowing Waters. From 1 July 2026, the company will be fully operational and responsible for managing 90,700 drinking water and wastewater connections across our fast-growing city and district.
We will have transferred staff, assets, liabilities, consents, contracts and land. The water assets of both councils (such as plants and equipment) as well as water-related debt will also be transferred to the company. Over the next decade IAWAI – Flowing Waters will be responsible for investing around $3.3 billion on critical water infrastructure.
The Establishment Board
Three independent Directors have been appointed to govern IAWAI – Flowing Waters. The Directors are Kevin Lavery, Tim Manukau (Tainui Waka) and Dave Chambers. Kevin Lavery has been appointed as the Executive Chair and will act as a chief executive of IAWAI – Flowing Waters until a chief executive is appointed. That is unlikely to be until late – 2025.
IAWAI – Flowing Waters welcomes the public to attend our monthly board meetings.

Shareholding arrangements
IAWAI – Flowing Waters is owned by Hamilton City Council and Waikato District Council. There are no other shareholders. Both councils have equal (50:50) voting rights.
Both councils have three representatives each on the IAWAI – Flowing Waters Forum, alongside three representatives from Waikato-Tainui. It is this Forum which makes Board appointments, Waikato-Tainui has voting rights for Board appointments only.
Councils provide strong direction to the IAWAI – Flowing Waters through a range of means including the formal Shareholders Agreement and Company Constitution.
A Water Services Delivery Plan was approved in June 2025 and is now with the government for approval. The plan outlines how the company will ensure there is sufficient revenue, sufficient investment and sufficient debt to meet water services needs across the city and district.
Our customers
Initially, customers will not see a lot of change.
Ratepayers in the Waikato district will still receive water meter bills, twice yearly. Industrial and commercial water users in Hamilton will also continue to get water meter bills.
But there will be a change for residential water users in Hamilton. From 1 July 2025, two things will change to ensure more transparency around the cost of water services.
Hamilton residential water customers will see a difference on their rates bills. They will see three separately itemised rates for waters services – drinking water, wastewater, stormwater – depending on what water services the property receives. That change will be in place for 12 months.
