Technical & Operations

The NTU Technical portfolio is made up of the Asset Management, Operations and Stormwater (AMOS) workstreams.  The AMOS teams work closely with water services experts from 67 councils, iwi/Māori, regulators, and the wider water sector to be able to move areas of three waters management and service delivery to 10 publicly owned Water Service Entities (WSEs) from 1 July 2024.


The three AMOS workstreams - Asset Management, Operations, and Stormwater - work collaboratively to manage interdependencies.  

Asset Management

The Asset Management team focuses on ensuring that each WSE has an Asset Management Plan (AMP) covering drinking water, wastewater, and stormwater in place from 1 July 2024. These plans will include managing performance and risk, capital and operational investment planning and asset management practices and improvements. 

Additionally, the team is responsible for maintaining infrastructure investment through transition, developing a National Code of Practice, and National Growth and Land Development Transition Guidelines.


Operations focuses on continuing delivery of the three water services and a smooth transfer of all operational functions from councils to the WSEs. The work will identify any non-standard operations so risks and liabilities can be proactively managed.  

A key project includes the development of Day 1 regulatory expectations, including those for Health and Safety and Resource Consents.


The stormwater workstream will define the plan for the transfer of stormwater assets and management of stormwater systems and infrastructure.  This includes managing the interface between the roles and functions of the proposed WSEs, local authorities, mana whenua, transport providers, and regional councils to work together to manage stormwater systems and functions.

Key projects include developing an approach and timeframe for transferring the responsibility for managing stormwater from local authorities to the WSEs and identifying stormwater roles and responsibilities to support the development of relationship arrangements and service level agreements.
