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.

Summary of heavy trucks and trailers first registered in March
This information is put together from information provided by the NZ Transport Agency statistical analysis team and through the Open Data Portal.

Vehicle type
This summary includes data from two heavy truck classes and one heavy trailer class.
A goods vehicle is a motor vehicle that:
(a) is constructed primarily for the carriage of goods;
(b) either:
(i) has at least four wheels; or
(ii) has three wheels and a gross vehicle mass exceeding one tonne.

Note: vehicle classes are not the same as RUC vehicle types or driver licence classes.

RUC purchases March 2020 for selected types

The red dots represent the cost of RUC purchased for that RUC type for the year to date March 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.
