On April 15, 2016 Associate Minister of Transport, Craig Foss, amended the VDAM Rule to provide bus and coach operators with access to heavier axle mass limits or weight, through permits.
The amendment extends the October 2015 amendment, which allowed increased axle mass for high-capacity urban buses. Now all buses or passenger service vehicles, irrespective of capacity or type will be able to apply for a permit.
Changes to the Vehicle Dimension and Mass Rule (2002) enable modern, safer buses, able to carry more passengers between regions. These changes, which came into effect on 15 April 2016, increase the allowable axle loads on buses to be similar to levels for HPMV trucks.
The NZ Transport Agency pavements staff carried out an analysis of the relative pavement loadings for these buses compared to loadings on standard buses.
