- road network inspections and field validation of proposed programmes
- legalisation of existing road reserves
- management of the stock of bailey bridges (NZTA only)
- special road maintenance or renewal-related studies.
Legalisation of existing road reserves

Road asset management systems
As a condition of receiving funding assistance for maintenance and renewal of roads, the NZTA requires the use of a road asset management system for treatment selection.
Inventory data
The road asset management system must include an inventory of the road assets, and a record of maintenance renewal and improvement activities. The inventory data must include the following:
| Traffic features | Road condition | Road features | Other |
|---|---|---|---|
Traffic volumes Traffic facilities Traffic loadings |
Surfacing and rehabilitation profile Condition rating Roughness |
Carriageway Shoulders Pavement layers Drainage facilities Structures Street lights |
Asset age Features Design lives Costs Treatment history |
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 500 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 RCA 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, accepted by the NZTA, 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
- intervention criteria related to the above agreed with the NZTA.
