Health and Safety at Work Act 2015: Plant, structures, and hazardous work

In May 2021 changes were proposed to the regulations that sit under the Health and Safety at Work Act 2015.

This work is currently on hold

The Minister for Workplace Relations and Safety has recently announced a public consultation on the wider work health and safety regulatory system.

Have your say: Work health and safety

Further work on the Plant and Structures regulations is therefore currently on hold, pending the outcome of the public consultation on the wider work health and safety system. The next steps for the Plant and Structures work will be informed by the feedback received during the public consultation on the wider system.

May 2021 policy decisions

In May 2021 the Government agreed to policy reforms following public consultation in 2019 on options for effectively managing risks to work involving plant, structures, and hazardous work at height and on excavations. These changes aim to provide more clarity and certainty for businesses, and better health and safety for workers.

This isn’t about creating cumbersome new requirements; it’s about ensuring better regulations to keep workers safe. In the last decade, an average of 54 people died at work each year from injuries involving plant (such as workplace machinery, vehicles and equipment) and structures (such as scaffolding and excavations).

The existing regulations are outdated and full of gaps. They are being modernised to ensure they are clear, effective, proportionate, and durable. By updating the regulations, businesses will be supported to better manage the risks in their workplaces and reduce work-related harm and fatalities.

The improved regulations will bring New Zealand up to international health and safety standards. New Zealand’s work-related injury fatality rate is comparatively high, approximately twice that of Australia and 4 times the rate of the United Kingdom.

The proposals for improvements included:

  • Appropriate guarding for dangerous workplace machinery.
  • Mobile plant, such as quad bikes and side-by-side vehicles, will need to have a suitable combination of devices to protect the operator, such as roll-over and crush protection, helmets, and seatbelts as appropriate.
  • High-risk plant such as cranes and boilers will continue to be regularly inspected but will also need to be registered with WorkSafe New Zealand.
  • More types of plant, such as steep-slope forestry equipment, will undergo design checks and be required to be regularly inspected to ensure they’re in a safe condition.
  • Managing risks across the supply chain by clarifying existing requirements of designers, manufacturers, importers, and suppliers of plant.
  • Clearer and stronger rules for working at heights, with the right level of protection based on the level of risk involved.
  • Clearer requirements for managing the risks of excavation work, including a “check before you dig” requirement for underground services.
  • Offences for breaching the regulations that are proportionate to the risk of harm.

This is part of the regulatory reform programme to continue implementing the Health and Safety at Work Act 2015.

July 2019 plant and structures consultation process

In July 2019, the Government released a discussion paper that sought feedback on how to improve protections for people working with plant, structures, and hazardous work.

The discussion paper covered:

  • Plant
  • Mobile plant
  • Design, manufacture, supply, import and installation of plant or structures
  • High-risk plant
