Reliable and consistent identification of defects is vital to the proper functioning of NZ Transport Agency (NZTA),  Road Assessment and Maintenance Management system.

NZIHT trains all of this country’s road condition raters directly. Successful workshop participants receive a Practising Certificate enabling them to undertake condition rating surveys of sealed roads on NZTA funded works on State Highways and Local Authority roading networks.

NZIHT welcomes inquiries for training from anyone wishing to be trained as a condition rater. The Institute maintains a register of currently certified sealed road raters for public inspection and will on request provide details to road controlling authorities prior to acceptance of any professional services tender for road condition rating.

Two Day Course

New Raters (with less than 2 years experience) are required to:
- attend the full two day Road Condition Rating course
- attend the one day “refresher” workshop the following year.

After two consecutive years training, raters are then considered experienced and only need to attend the one day “refresher” course every second year.

One Day Course (2nd Day)
Experienced Raters are those who have attended two consecutive years training. To remain current, they must attend the one day “refresher” course every second year. i.e. if you attended a 1 day course within the last 12 months, then you are not required to attend again until 2023.
