New Zealand Trucking shows you how the economy is travelling via key metrics from the road transport industry. From time to time we‘ll be asking experts their opinion on what the numbers mean.

Rolling trend month-on-month purchase of RUC during 2019 – 2020

RUC purchases year to date (end of February 2020) for selected RUC types.

RUC class RUC value ($) RUC Distance (Km) Cents/km
2 $29,794,401 201,889,775 $0.15
6 $44,318,200 109,059,281 $0.41
43 $19,630,981 86,656,581 $0.23

33 $6,331 ,018 35,961 ‘168 $0.18
408 $8,687,209 22,909,656 $0.38
Total Year to Date $167,538,101

The red dots represent the cost of RUC purchased for that RUC type for the year to date (end of February 2020) only, thus for RUC type 6 vehicles, powered vehicles with three axles, (except type 308, 309, 311, 399 or 413 vehicles), the higher value results from the high cost of RUC for these type vehicles above 12 tonne.
