The Asset Management Data Standard (AMDS) was established to support the complete asset management lifecycle, whereas many traditional data standards have been developed from a maintenance management perspective.

When comparing to a traditional data standard, a common difference is the AMDS has been designed to support methods or processes on the network rather than at the asset level. This model enables us to reflect the activities that occur around the assets rather than capturing information against the asset itself. 

Supporting the complete Asset Management Lifecycle enables us to monitor trends in impacts, service performance or asset condition targeting the right intervention in the right place and the right time by providing better consistent data. This will help Waka Kotahi NZ Transport Agency improve understanding of when and why maintenance renewal and improvement activities are needed, what different roadworks can achieve and cost, and how they should be designed and scoped to address all service defects and outcomes together for least disruption.

AMDS is intended to support current and future multimodal networks and reflect the planning and design activities around that for asset management.

Examples include:

  • By supporting a pedestrian network model where significant parts of that network have no infrastructure (eg intersections, rail crossings), this improves forecasting and measurement of pedestrian traffic which could be used to resolve defects which make cause injury.
  • When road usage changes from 2 to 3 lanes carrying greater traffic through put, the collection of demand is based on the infrastructure rather than fixed to the pavement asset.
  • Outside lanes of a road are re-allocated for use as a cycleway, not for general traffic use. The function and demand is linked to the network rather than a particular asset. This could assist in route ability of people cycling.

Collaborating with the sector

The success of the AMDS programme to develop and deliver a national, shared standard for roading asset management relies on a collaborative effort between Waka Kotahi and the wider local government and transport sector.


  • In collaboration with SMEs from maintenance contractors and professional services consultants including Fulton Hogan, Downer, Higgins and WSP along with representatives from Road Controlling Authorities (RCAs).
  • Developing inventory assets and the management of the asset over its lifecycle (eg faults, conditions, observations, controls) enabling key performance measures to be captured.
  • The published standard is publicly available for Asset Management Solution (AMS) technology providers to use in their AMS systems.
  • Understanding the type and level of support RCAs need to implement the standard, and working with RCA data experts, maintenance contractors and professional services to facilitate rollout of the standard.
