Introduction to the Health and Safety at Work Act 2015 - special guide (PDF 640 KB)

This quick reference guide summarises the key components of HSWA including the roles and responsibilities of PCBUs, officers, workers and others in managing workplace health and safety risks.

Foreword

In 2013, the Independent Taskforce on Workplace Health and Safety reported that New Zealand’s work health and safety system was failing. As a result, New Zealand underwent its most significant workplace health and safety reforms in 20 years resulting in the Health and Safety at Work Act 2015 (HSWA) and the formation of WorkSafe New Zealand (WorkSafe).

This guide provides a plain English explanation of key requirements under HSWA and the role of WorkSafe. It gives examples to explain certain concepts and directs readers to where they can find guidance on how to meet regulatory requirements.

As this guide will be updated regularly, please check the WorkSafe website for the latest version.

Concepts

The Health and Safety at Work Act 2015 (HSWA)

New Zealand’s key work health and safety legislation is the Health and Safety at Work Act 2015 (HSWA) and regulations made under that Act. All work and workplaces are covered by HSWA unless specifically excluded.

WorkSafe
New Zealand (WorkSafe)

WorkSafe is the government agency that is the work health and safety regulator.

Designated agencies are government agencies other than WorkSafe designated to carry out health and safety functions for certain sectors.

The regulator means WorkSafe or a relevant designated agency.

Duty holders under HSWA

A duty holder is a person who has a duty under HSWA. There are four types of duty holders – PCBUs, officers, workers and other persons at workplaces.

A PCBU is a ‘person conducting a business or undertaking’. A PCBU may be an individual person or an organisation.

This does not include workers or officers of PCBUs, volunteer associations, or home occupiers that employ or engage a tradesperson to carry out residential work.

A PCBU must ensure, so far as is reasonably practicable, the health and safety of workers, and that other persons are not put at risk by its work. This is called the ‘primary duty of care’.

See Sections 2-3 of this guide for more information about PCBUs.

An officer is a person who occupies a specified position or who occupies a position that allows them to exercise significant influence over the management of the business or undertaking. This includes, for example, company directors and chief executives.

Officers must exercise due diligence to ensure the PCBU meets its health and safety obligations.

See Section 5 of this guide for more information about officers.

A worker is an individual who carries out work in any capacity for a PCBU. A worker may be an employee, a contractor or sub-contractor, an employee of a contractor or sub-contractor, an employee of a labour hire company, an outworker (including a homeworker), an apprentice or a trainee, a person gaining work experience or on a work trial, or a volunteer worker. Workers can be at any level (eg managers are workers too).

Workers have their own health and safety duty to take reasonable care to keep themselves and others healthy and safe when carrying out work.

See Section 6 of this guide for more information about workers.

Other person at workplace

Examples of other persons at workplaces include workplace visitors and casual volunteers at workplaces.

Other persons have their own health and safety duty to take reasonable care to keep themselves and others safe at a workplace.

See Section 7 of this guide for more information about other persons at workplaces.

1. About the Health and Safety at Work Act 2015

1.1 What the Health and Safety at Work Act 2015 (HSWA) sets out to do

The Health and Safety at Work Act 2015 (HSWA) is largely based on the Australian work health and safety law but with changes to reflect the differences between the New Zealand and Australian working environments.

It recognises that a well-functioning health and safety system relies on participation, leadership, and accountability by government, business and workers.

Purpose of HSWA

A guiding principle of HSWA is that workers and other persons should be given the highest level of protection against harm to their health, safety, and welfare from work risks as is reasonably practicable.

The main purpose of HSWA is to provide for a balanced framework to secure the health and safety of workers and workplaces by:

HSWA is flexible and workable for all businesses and undertakings

The legislation is designed to be flexible and workable for both small and large businesses and undertakings without imposing unnecessary compliance costs.

The work health and safety legislation:

Work health and safety regulator

WorkSafe is the work health and safety regulator.

In addition, other government agencies (called designated agencies) can be designated to carry out health and safety regulatory functions for certain work, for example:

In this guide, the term ‘regulator’ means WorkSafe or the relevant designated agency.

1.2 Key concepts in HSWA

Coverage is broad

HSWA applies to nearly all work in New Zealand.

However, there are exceptions. For example, HSWA does not apply to:

Business and working relationships covered

All types of modern business and working relationships are covered under HSWA (eg the relationship between franchisors and franchisees).

Focus on work

Most duties under HSWA relate to the conduct of work. However, while the focus is on the work being carried out and how it can affect workers and others, there are certain duties that relate to the physical workplace.

A workplace is a place where a worker goes or is likely to be while at work, or where work is being carried out or is customarily carried out. It includes a vehicle, vessel, aircraft, ship or other mobile structure, and any waters and any installation on land, on the bed of any waters, or floating on any waters.

Focus on both work-related illnesses and injuries

Whoever creates the risk manages the risk. HSWA requires health and safety work risks to be managed. This means consideration of the potential work-related health conditions as well as the injuries that could occur. Health conditions include both physical and psychological acute and long-term illnesses.

Four types of duty holders

There are four types of duty holders that have work health and safety duties:

These duties are discussed later.

A person may have more than one duty (eg a person can be a PCBU and a worker). More than one person may have the same duty (eg different PCBUs may have the same duty towards the same worker).

Duties are not transferable or able to be contracted out of, but reasonable arrangements can be entered to ensure duties are met.

HSWA special guide fig 1

1.3 So far as is reasonably practicable (section 22 of HSWA)

The primary duty of care requires a PCBU to ensure health and safety ‘so far as is reasonably practicable’. When used in this context, something is reasonably practicable if it is reasonably able to be done to ensure health and safety, having weighed up and considered all relevant matters, including:

Lastly weigh up the cost:

For worker engagement and participation duties, the above definition does not apply.

1.4 How HSWA, regulations, safe work instruments, Approved Codes of Practice, and guidance work together

HSWA, regulations, safe work instruments (SWIs) and WorkSafe information, guidance and advice work together to improve work health and safety.

The work health and safety legislation

HSWA is the key work health and safety law. It sets out the health and safety duties that must be complied with.

Health and safety regulations sit under HSWA, and prescribe certain requirements to be met for certain duties under HSWA (see Appendix 2 of this guide for a list of the health and safety regulations). For example, there are regulations about what workplace facilities are required.

SWIs set out further technical rules in relation to matters covered by regulations (eg variations to control measures for specific substances).

Other legislation may affect work health and safety (eg the Gas Act 1992 and the Building Act 2004). Where two pieces of legislation apply, the duty holder needs to follow both. HSWA addresses such overlaps by providing that other legislative requirements can be considered when deciding if health and safety duties are being met. However, duty holders may need to do more than what other legislation requires to meet HSWA duties.

Example

An architect that designs a building has duties under HSWA to ensure health and safety, and must also ensure the design complies with the Building Act. Under HSWA the requirements of the Building Act will be taken into account in determining what is required to comply with the architect’s HSWA duties.

There is other legislation that applies to work, such as the Employment Relations Act 2000.

WorkSafe guidance and information

WorkSafe produces a range of information and guidance to help people comply with their health and safety duties.

Figure 2 shows the relationship between the law and WorkSafe guidance and information.

WorkSafe produces a range of products including:

Other publicly available items include:

Figure 2 explains what these are.

Guidance has been produced on the work health and safety duties under HSWA and regulations.

Other guidance is referred to as appropriate in this guide.

In addition to WorkSafe guidance, there may be industry-directed health and safety guidance available.

2. What is a PCBU?

2.1 The meaning of a PCBU (section 17 of HSWA)

A PCBU is a ‘person conducting a business or undertaking’. While a PCBU may be an individual person (eg a sole trader) or an organisation, in most cases the PCBU will be an organisation (eg a business entity such as a company).

While the terms ‘business’ and ‘undertaking’ are not defined in HSWA, the usual meanings of these terms are:

2.2 Examples of PCBUs

Individuals or organisations can be PCBUs. A PCBU will usually be a legal entity, but HSWA also makes it clear that it could be a body of persons. Examples of PCBUs are:

2.3 People and organisations that are not PCBUs

The following are not PCBUs:

Example

Kitchen Construction Limited (KCL) operates a small business which specialises in building and renovating kitchens. Simon is KCL’s sole director. KCL employs several full-time staff and regularly contracts Jill, a self-employed electrician, to do electrical work for KCL’s projects.

Volunteer associations

Volunteer groups that meet the definition of ‘volunteer associations’ are not PCBUs.

A volunteer association is a group of volunteers working together for one or more community purpose, where none of the volunteers, nor the association as a whole, employs anyone to carry out work for them. Community purposes could include the promotion of art, culture, science, religion, education, medicine, or for charity, sport or recreation purposes.

Volunteer groups that only engage contractors (eg instead of having employees) are not classed as PCBUs. Contractors are PCBUs in their own right.

Example

Monica, a nurse at the local hospital, set up a group of keen knitters to knit clothing for babies (Knitting for Babies) two years ago. At first the knitting was only donated to the hospital, where it was used for premature babies. Recently the group has grown substantially and now also knits jumpers and other clothes for older babies. These jumpers are given to Plunket and the Salvation Army to distribute more widely in the community to those in need.

Example

The demand for knitted baby clothes became so great that there is not enough donated wool. Knitting for Babies decided to raise money by selling a wider range of knitting at community fairs and on the group’s newly established website. The group became an incorporated society, Knitting for Babies Incorporated, and employed Roger on a part-time basis to take care of all administration and accounting matters.

Example

Happier Homes is a charity organisation that finds homes for abandoned pets. It is run by volunteers. Happier Homes contracts an IT specialist to create a website to promote their cause.

Example

Happier Homes has now expanded and needs someone to manage the administration of the organisation.

Home occupiers

A home occupier who employs or engages another person to only do residential work (domestic work done in the home, or other work on the home itself) is not a PCBU. However, a home occupier is a PCBU if they operate a business from their home.

Example

Mary owns a small lifestyle block and wants to keep chickens and plant a large garden to provide fresh eggs and vegetables for her family of eight. The property is not connected to the town water supply. Mary has engaged Maximum Plumbing Limited (MPL) to upgrade the house’s plumbing and secondary water tank to make sure there is enough water for the animals, garden and her family. Three plumbers from MPL will be working in and around Mary’s home for several days to finish the upgrade.

Example

Peter, a self-employed chef, has started his own business to provide healthy, home-cooked meals to people. Peter runs the business from his home and contracts a local courier company (who employs a driver called Sandy) to deliver the pre-cooked meals to customers. Peter purchased a larger oven to put in his kitchen and engaged Todd, a self-employed electrician, to install the oven and complete some necessary upgrades to his house’s wiring to accommodate the larger oven.

3. PCBU duties

3.1 Primary duty of care (section 36 of HSWA)

A PCBU must ensure, so far as is reasonably practicable, the health and safety of workers, and that other people are not put at risk by its work. This is called the ‘primary duty of care’.

This means ensuring, so far as is reasonably practicable:

A PCBU who is a self-employed person must also ensure, so far as is reasonably practicable, his or her own health and safety while at work.

The primary duty of care is a broad overarching duty. It includes, but is not limited to, so far as is reasonably practicable:

PCBUs must also maintain any worker accommodation that is owned or managed by the PCBU and provided because other accommodation is not reasonably available. The PCBU must, so far as is reasonably practicable, maintain the accommodation so the worker is not exposed to health and safety risks arising from the accommodation.

PCBUs cannot contract out of their duties, but can enter reasonable agreements with other PCBUs to meet their duties.

These duties are explained below.

Providing and maintaining a work environment that is without risks to health and safety

PCBUs must, so far as is reasonably practicable, provide and maintain a work environment that is without health and safety risks.

The work environment includes:

The health and safety regulations that sit under HSWA cover duties to manage certain work risks.

Providing and maintaining safe plant and structures

PCBUs must, so far as is reasonably practicable, provide safe plant and structures, and maintain them in good condition.

‘Structure’ means anything that is constructed. It can be fixed, movable, temporary or permanent, and includes any component or part of a structure. The following are examples of structures:

Providing and maintaining safe systems of work

PCBUs must, so far as is reasonably practicable, provide and maintain safe systems of work (eg work processes).

Developing a safe system of work is a formal procedure carried out by a person with sufficient knowledge and experience. It involves:

The development of safe systems of work can involve looking at the physical layout of the workplace and its access and egress, tools, plant, procedures and people (eg instruction, information, training).

For risky work, safe work methods can be formalised using a permit-to-work system.

Systems of work should be reviewed on a regular basis and updated as appropriate.

Ensuring the safe use, handling and storage of plant, structures, and substances

PCBUs must, so far as is reasonably practicable, make sure that plant, structures, and substances are safely used, handled and stored.

Providing adequate facilities for the welfare at work of workers in carrying out work for the business or undertaking, including ensuring access to those facilities

PCBUs must, so far as is reasonably practicable, provide adequate facilities (that are clean, safe, accessible, in good working order and maintained to stay that way) for the welfare of workers.

Providing any information, training, instruction, or supervision that is necessary to protect all persons from risks to their health and safety arising from work carried out as part of the conduct of the business or undertaking

PCBUs must, so far as is reasonably practicable, make sure its workers and others are provided training, information, instruction or supervision to protect them from risks to health and safety.

The type of training, instruction or supervision required will depend on the nature of the work carried out and the experience of the workers, and the risk that workers and others, such as clients and customers, are exposed to.

Monitoring the health of workers and the conditions at the workplace for the purpose of preventing injury or illness of workers arising from the conduct of the business or undertaking

Exposure to certain hazards can injure workers or make them ill. This can include exposure to:

A PCBU must, so far as is reasonably practicable, monitor its workers’ health and the workplace conditions. Monitoring is not a control measure to manage risk and does not replace the need for control measures to reduce exposure. Results from monitoring should be used to improve control measures where needed.

Workplace monitoring

Workplace monitoring can involve measuring a hazard (eg a substance, fumes, noise or vibrations arising from the work). The purpose of the monitoring is to assess the effectiveness of controls being used to minimise the risk of workers developing a work-related condition or getting injured on an ongoing basis.

Health monitoring

Health monitoring involves specific and targeted testing of the health of workers to identify potential signs of potential harm to their health and any changes on an ongoing basis. As well as identifying the development of work-related conditions, the purpose of monitoring is to assess the effectiveness of control measures designed to minimise potential harm to worker health on an ongoing basis.

Providing healthy and safe worker accommodation

In some situations a PCBU provides its workers with accommodation that it owns, or manages or controls, where this is necessary because other accommodation is not reasonably available.

If this is the case, a PCBU must, so far as is reasonably practicable, maintain the worker accommodation so that workers are not exposed to health and safety risks arising from the accommodation.

3.2 Duties of PCBUs with volunteers

Certain volunteers are classed as volunteer workers. A volunteer is a ‘volunteer worker’ when:
