This amendment to Land Transport Rule: Vehicle Dimensions and Mass 2002 (the principal Rule) expands the limited changes that came into effect on 1 October 2015 which introduced permits for higher axle mass, but only for high capacity urban buses (such as the double-decker buses recently entering service in Auckland).
This change will allow the operators of any bus to apply for the higher mass limits set out in the principal Rule.
From 15 April 2016, road controlling authorities (including the NZ Transport Agency, city or district councils, and Auckland Transport) will be able to consider and issue permits for any bus, not just the largest vehicles in service on commuter routes.
The amendment Rule comes into force on 15 April 2016.
This amendment extends the availability of permits for higher mass limits (previously available only for double-decker urban buses), to a wider range of buses and routes. This allows for more efficient use of some larger buses on inter-city routes and is expected to also assist with the introduction of new technology for buses.
No, not all buses benefit – increased axle mass is only of benefit to larger or heavier buses.
Smaller to medium buses operate well within the current general access axle loadings. Other buses are constrained by other limits, such as the manufacturer’s rating for axle loading. Permits cannot allow a bus to exceed a design limit for the vehicle.
Permits for buses are also limited by the fit-out of existing vehicles, particularly the number of seats installed – additional capacity is not easily provided.
The increase in allowed axle mass through a permit widens the range of vehicles that can comply with our mass limits – providing options when considering which buses to purchase.
Allowing higher axle mass may assist (limited) introduction of hybrid and pure electric buses. These vehicles are generally heavier than conventional vehicles (e.g. by adding storage batteries).
Larger inter-city buses also benefit – previously some of these vehicles could not load to their full capacity without exceeding the allowed axle mass limits.
The CoL does still limit the number of passengers allowed on a bus – a permit cannot allow passenger loadings that exceed the number allowed by the CoL. However, a bus is not allowed to load to its full CoL passenger limit if this would exceed the mass limit contained in the principal Rule, either under general access or permitted limits. This amendment is designed to make this less of an issue for many heavier buses.
We expect a small safety benefit through fewer buses being required to carry the same number of passengers.
In considering permit applications, road controlling authorities (RCAs) must consider the safety of the vehicle and other road users, as well as the suitability of the intended routes for heavier axle loads.
Yes, higher axle loadings do create increased pavement wear. Therefore, before issuing a permit, the road controlling authority (RCA) should consider the impact of the additional weight on the routes that are specified in the permit application.
All RCAs have to agree to the issue of the permit if it includes roads managed by more than one authority.
Heavy vehicles used on New Zealand roads pay a proportional charge related to the estimated road wear they cause.
Vehicles operating above the standard axle limits are generally subject to higher RUC rates. A RUC rate for buses with three axles operating with a permit has already been set. New rates would be considered if permits are issued to buses with two axles.
Yes. A consultation draft of the amendment Rule, together with explanatory material, was published on the NZ Transport Agency’s website on 20 November 2015 and advertised in the five major daily newspapers. A notice of the consultation was sent to over 1400 groups and individuals, who have registered an interest in the Vehicle Dimensions and Mass Rule, inviting comments. The NZ Transport Agency received 19 submissions on the proposed change, which were taken into consideration in finalising the amendment Rule.
A copy of the amendment Rule will be available for purchase from selected bookshops that sell legislation or from Wickliffe Solutions, telephone 0800 226 440.

This is an amendment Rule, and, therefore, contains only the amending provisions. The amendment Rule should be read in conjunction with the principal Rule. The principal Rule is also available on the Transport Agency’s website. A consolidated version of this Rule, incorporating the amendment, is available on this website from 1 April 2016: http://www.nzta.govt.nz/resources/rules/vehicle-dimensions-and-mass-2002-index/(external link)
