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. In this first report we look back at the 2019 numbers.

Month-on-month purchase of RUC during 2019

The greatest RUC purchases made during 2019 were for type 1 vehicles, powered vehicles with two axles (except type 2 or type 299 vehicles). Vehicles in this type include vans, light trucks, SUVs and utes, and light cranes. Type 1 purchases were: 11,503,966,413 kilometres that cost $812,973,322.

RUC purchases for the top eight RUC types
The top eight RUC type purchases, other than type 1, for 2019 in descending order were:

RUC Type Description
2 Powered vehicles with one single-tyred spaced axle and one twin-tyred spaced axle
6 Powered vehicles with three axles (except type 308, 309, 311, 399 or 413 vehicles)
43 Unpowered vehicles with four axles
14 Powered vehicles with four axles (except type 408, 414 or type 499 vehicles)
951 Unpowered vehicles with five or more axles
H94 Towing vehicle that is part of an overweight combination vehicle consisting of a type 14 RUC vehicle towing a type 951 RUC vehicle with a permit weight of not more than 50,000kg.
33 Unpowered vehicles with three twin-tyred, or single large-tyred, close axles (except vehicle type 939)
408 Towing vehicles with four axles that are part of a combination vehicle with a total of at least 8 axles

The red dots represent the cost of the RUC purchased for that RUC type for all of 2019 only, thus for RUC type 6 vehicles, powered vehicles with three axles (except type 308, 309, 311, 399 or 413 vehicles), the higher cost results from the high cost of RUC for these type vehicles above 12 tonne.
