Standards for heavy vehicles

Updated: 28 January 2010

Heavy vehicles include heavy buses, trucks and trailers. With their large mass, these vehicles have added challenges in braking effectively and within safe stopping distances. That's why heavy buses and trucks first registered in New Zealand after 1 July 2008 have to meet an approved heavy brake standard. Additionally, most heavy trucks used to tow heavy trailers need to be fitted with ABS, ESV or LSV. This section sets out the specific requirements the different classes of heavy vehicles must meet.

Many heavy vehicles need modification to meet additional New Zealand requirements. These include:

  • load anchorage standards
  • drawbeam/drawbar standards
  • logging bolster attachments
  • chassis modifications
  • stability and rollover.

You can make these modifications once you've imported your vehicle to New Zealand. In most cases, a heavy vehicle specialist certifier must certify the vehicle before it can be registered for use on the road. Find out more about heavy vehicle modifications.

Before you can register your heavy vehicle

It must have a chassis rating. Contact an entry certifier for the chassis rating application forms and procedure.

Heavy vehicles and road safety

Any injuries or loss of life on New Zealand roads is unacceptable. Through road safety strategies, we're working to improve the safety of travelling on our roads. These strategies include interventions such as regulations, education and safety promotion - activities all aimed at getting New Zealand's road toll down.

You can improve your safety on the road by ensuring any heavy vehicles you use meet the requirements of the Heavy Vehicle Brakes Rule and the static roll threshold.

In making your heavy vehicle purchase decision you need to weigh factors of economy and efficiency. You also need to consider the benefits of investing in vehicles that feature crash prevention advances such as electronic stability control. Such engineering advances are a component of the latest road safety strategy Road Safety to 2020 (external link).
