Site Health & Safety

Health & Safety compliance

Your installer is required UNDER LAW to comply with the requirements of the Health & Safety in Employment Act and Regulations.  Protection of workers when working at height is mandatory under the Act and essential for their personal safety and safety of others on the site.

Government's Labour Group guidelines set out the safety requirements required -

  1. DoL best Practice Guidelines for the Prevention of Falls in New Zealand;  and
  2. DoL Best Practice Guidelines for Working on Roofs

These guidelines can be viewed or downloaded from the Ministry of Business Innovation & Employment website:

Installation of health & safety protection equipment is a cost to the property owner which may include (but not limited to) edge protection or scaffolding. The installation company should advise you of what health & safety equipment is required for your particular job.  This information and the cost should be clearly detailed on the written quotation/contract.

Safety steps should be outlined in your contract

If work on your building involves work at height, contractors need to ensure the right safety steps are in place before the work starts. If you can’t see them, ask your contractor for them.

The Ministry of Business, Innovation and Employment is running a programme to reduce the number of injuries and deaths that result from falls from height in New Zealand construction.

More than half the falls reported to the Ministry’s Labour Group from the construction sector occur from less than three metres, and most of these falls are from ladders and roofs. The cost is estimated at $24 million each year.

Everyone must ensure that they are safe when working at height. This includes selecting the right equipment for working safely at height, for example edge protection, scaffolding, using a mobile elevating work platform (MEWP), or a total restraint system.

The Labour Group has made it clear to the construction sector that doing nothing is not an option.

You should expect to see an explanation of how safety will be achieved when engaging a contractor for work that will be carried out at height. This may include quotes and method statements which set out safe work procedures and details of safety equipment.

Contractors who choose to work unsafely are at risk of seriously injuring themselves and their workers. Health and safety inspectors will stop any work at height until they are satisfied that it can be achieved safely. This may impact on work on your building, so make sure the contractor is doing the right thing at the beginning.

For further information about working safely at height and the Labour Group’s enforcement approach for preventing falls from height: or call 0800 20 90 20.

If you observe unsafe work practices on your building, call the Labour Group on 0800 20 90 20.

Ensure work on your building is safe.
