This work category provides for the general management and control of the road network and management of road assets. Funding assistance is subject to the condition of funding set out below.

The following details apply to the 2018–21 NLTP.

Qualifying activities

The work category includes a range of qualifying activities.

  • Examples of qualifying activities

    Examples of qualifying activities

    Examples of qualifying activities include, but may not be limited to:

    • management of the road network
    • promotion and information activities (Network user information – see below) which maximise the efficiency of the road network in support of the activity management plan.
    • implementation and operation of road asset management systems
    • regular, routine updates to the activity management plan
    • roughness and condition rating surveys
    • traffic count surveys, including pedestrian and cycle counts
    • road network inspections and field validation of proposed programmes
    • routine refreshing of the asset deterioration model
    • maintenance and routine updating of transport models
    • legalisation of existing road reserves as specified below
    • management of the stock of bailey bridges (Transport Agency only)
    • special road maintenance, renewal or improvement related studies that do not fit the Transport Planning work categories' description, eg KiwiRap studies
    • professional services for road maintenance activity classes other than for operational traffic management and emergency works.

    Other potential activities that are not in the above list should be discussed with the Transport Agency for eligibility.

Applying for funding approval

Applications for funding approval should be made through the Maintenance module in Transport Investment Online(external link) (TIO).


See the Professional Services policy page for more details.

Condition of funding – road asset management system

As a condition of receiving funding assistance for road maintenance, the Transport Agency requires the use of a road asset management system for treatment selection, which will include the following inventory data:

Road conditions

Road features


Surfacing and rehabilitation profile

Condition rating




Pavement layers

Drainage Facilities


Street lights

Asset age


Design lives


 Treatment history

Classification (using the One Network Road Classification system)

Roughness and condition rating surveys

Roughness and condition rating surveys of all sealed roads must be undertaken at least every second year.

Condition rating surveys of all sealed roads carrying more than 2000 vehicles per day are to be undertaken annually.

Renewal and improvement projects

The inventory database must be updated as soon as practicable after any project that affects the network is completed.

Training certificate required

In order for road condition rating work to be eligible for funding assistance, the raters acting on behalf of the Approved Organisation are required to hold a current certificate issued by the New Zealand Institute of Highway Technology (NZIHT), following satisfactory performance at a rating training workshop.

Treatment selection

Treatment selection shall be based on a methodology, acceptable to the Transport Agency, that takes into account the following (at the very least):

  • the road structure
  • the surface type and age
  • the measured condition, including roughness
  • traffic volumes, and
  • intervention criteria related to the above agreed with the Transport Agency.

Network user information

The objective of network user information is to influence transport choices that contribute to the effectiveness and efficiency of the network through:

  • easing congestion
  • improving travel time reliability
  • making better use of existing transport capacity, and
  • advancing a resilient transport network.

Requirements for regional councils

Regional councils may apply for funding for Network user information from the Maintenance activity class through work category 151, if they meet the following requirements:

  • all regional council applications must be endorsed by the local authorities, and demonstrate that the activities have been coordinated with local interventions in order to maximise the efficiency of the transport network and the capacity and function of existing assets
  • a business case or implementation plan must support the application and detail the activities which will be undertaken, demonstrate the planning linkages, and detail how the interventions (options and alternatives) were selected
  • a benefit–cost ratio must be calculated for any activity with total cost greater than $1,000,000
  • a clear monitoring programme including targets should be included within the business case
  • reporting requirements of works completed and outcomes will be required as the equivalent physical reporting is not applicable.

Regional councils must provide additional information to support the application. You may choose to use the Road Safety Promotion activity list.
