What health and safety duties does the owner of a tiling business have in New Zealand?

What health and safety duties does the owner of a tiling business have in New Zealand?

New Zealand's main work health and safety law is the Health and Safety at Work Act 2015, usually called HSWA. WorkSafe is “the main regulator responsible for administering and enforcing HSWA,” according to its Working at height in New Zealand page. A tiler running a business, whether alone, with subbies, or with a crew, is what the Act calls a PCBU, a person conducting a business or undertaking, a status that covers sole traders through to companies, the same page says. That status brings the primary duty of care: “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,” says WorkSafe's introduction to HSWA guide.

For a tiler, that duty sits inside the ordinary run of a job: the adhesive and membrane carried on the van, the waterproofing in a wet area, the grout and screed underfoot, the ladder used to reach a splashback above a kitchen bench. None of that is separate from the business; it is the business.

Why does this apply even to a one person tiling business or a subbie on someone else's site?

A sole trader tiler working alone still carries the duty. The Act itself says “a PCBU who is a self-employed person must ensure, so far as is reasonably practicable, his or her own health and safety while at work,” according to the Health and Safety at Work Act 2015.

Most tiling work does not happen alone, though. A tiler is usually subcontracting to a builder or renovator, laying tile over someone else's floor preparation and screed, waiting on a plumber's rough in before waterproofing a bathroom, or sharing a site with an electrician fitting a heated floor mat under a shower recess. Where duties overlap across different trades on the same site, WorkSafe's guidance says “a PCBU must manage work health and safety risks,” and sets out that businesses sharing a site need to work together on those risks rather than leaving it to whoever happens to be on site that day, according to its guide to PCBU duties. A tiler cannot treat the builder's site as the builder's problem alone; the duty travels with the work.

What does a tiler's own trained eye already have to do with this?

You already walk a bathroom or wet area before you quote it, checking falls to the floor waste, the shower recess, and where the membrane needs to run before tiling starts. That same scanning habit, pointed at hazards instead of pricing, covers most of what the primary duty of care asks for. You are not starting from nothing on health and safety; you are starting from a habit the trade already trained into you.

Point that habit at the things that hurt people rather than the things that affect the quote. A levelling clip or spacer left lying on a wet floor is a trip hazard before it is rubbish to sweep up. An unguarded step down to a shower recess or wet area is a fall risk before it is a finishing detail waiting on grout. Cutting large format tiles indoors without ventilation builds up dust, and WorkSafe says “as a PCBU, you have a duty to eliminate, or use controls to minimise worker exposure to the hazard of, and risks from, RCS dust,” arising when tiles and similar materials are cut, ground, drilled, sanded or polished, according to its silica dust guide. Adhesive and sealer fumes in a closed up bathroom on a cold renovation day sit in the same category.

The same primary duty covers making sure anyone on site, including an apprentice or a subbie brought in for a bigger renovation, has the information and instruction needed to work safely, and that workers get a reasonable say in health and safety matters that affect them directly, according to WorkSafe's guide to HSWA.

What happens if someone gets hurt on a tiling job?

A business must notify WorkSafe when a serious injury, illness or incident happens to anyone carrying out work it is responsible for, or as a result of that work; “this is a requirement under the Health and Safety at Work Act 2015 (HSWA),” says WorkSafe's notification page. That applies whether the injury happens to an employee, a subbie on the same renovation, or a client walking through an unfinished wet area.

Workers carry duties too. In most cases the business must provide the protective equipment needed to keep a worker safe, such as eye and breathing protection for cutting tile, and “the business you work for cannot charge you for PPE,” according to WorkSafe's factsheet on rights and responsibilities. A worker may supply their own gear, but it has to be checked and approved by the business first, the same factsheet says.

How do AI agents and data first change how a tiler keeps on top of this?

An AI agent is software that does a job the way you would do it yourself, using your own prices, your own wording and your own rules, rather than a generic form filled in once and never looked at again. For health and safety paperwork, that means site inductions, PPE checks and incident records that match how your own tiling business runs, not a template built for a different trade.

Picture a tiler running a small crew across several renovation sites at once, where site inductions, incident forms and new starter paperwork were scattered across emails, a folder on the laptop in the ute, and whatever the last apprentice remembered, while team messages ran through a separate app again. The owner built his own app for the crew instead. It pulls in each job's own information and brings the forms, the site specific induction, an incident register and new starter onboarding together in one place, shaped around how his jobs actually run.

This is data first thinking: the record of who was inducted, what hazards were noted on a site, and what PPE was issued sits with the job itself, rather than living in someone's memory until an incident forces a search for it later. AI agents can carry that paperwork without pulling you away from the tools, freeing time for your crew and your customers instead of the admin.

How does Data First Coaching approach this?

Data First Coaching starts by looking at your own job and site records through the Trade Business Intelligence, not a generic safety checklist copied from a government page. Greg looks at where incidents, near misses or missed inductions actually sit in your business, whether that is a pattern of jobs with no written induction, subbies brought on without a record, or hazards noted but never followed up, because that is usually where the real problem starts rather than on the surface. Greg says the point of this work is that “we want to protect you and your team,” alongside protecting the business itself. The how, built around your own jobs and crew, is worked through inside the Academy, with members, because the Trade Business Intelligence is powered by every member who joins open minded, innovative and willing to share.
