How to manage contractor compliance on New Zealand worksites

Managing contractors on a busy worksite is one of the most demanding health and safety challenges NZ businesses face. Unlike direct employees, contractors come with their own employers, their own habits, and varying levels of familiarity with your site. Making sure they're compliant before they start work — and staying compliant while they're there — requires a system.

This guide covers the practical steps for managing contractor compliance on New Zealand worksites, from pre-registration to daily check-in.

Why contractor compliance matters

Under the Health and Safety at Work Act 2015, your duty of care extends to contractors on your site. If a contractor is injured because they weren't properly inducted, or because a hazard wasn't communicated to them, you can be held liable — even if they're not your employee.

WorkSafe New Zealand takes contractor management seriously. During incident investigations, one of the first things inspectors ask for is evidence of induction records and compliance checks. Businesses that can't produce this documentation face significantly more scrutiny.

Step 1: Pre-register contractors before they arrive

Contractor compliance starts before a person sets foot on your site. Pre-registration lets you collect essential information — company details, certifications, emergency contacts — and verify it before work begins.

At a minimum, your pre-registration process should capture:

• Full name and contact details
• Employing company
• Type of work being performed
• Required licences or certifications (trade licences, Site Safe card, etc.)
• Emergency contact

Pre-registration also gives you the opportunity to send induction materials in advance — so contractors arrive on day one already prepared, rather than spending the first hour of your (expensive) job time sitting through an induction.

Step 2: Require induction completion before site access

A site induction ensures every contractor understands the specific hazards and emergency procedures for your site. Unlike generic H&S training, a site induction is location-specific — it covers your layout, your emergency exits, your specific risks, and your rules.

The challenge with paper-based induction systems is enforcement. If someone slips through without completing their induction, there's no mechanism to catch it — until something goes wrong.

Step 3: Verify certifications and licences

Depending on your industry, contractors may be required to hold current certifications — a Site Safe card on construction sites, a Dangerous Goods licence in logistics, electrical registration for electrical work, and so on.

Common certifications to verify for NZ worksites:

• Site Safe passport — required or recommended on most NZ construction sites
• Electrical Worker registration — licensed electrical work under the Electricity Act
• Gasfitting licence — licensed gasfitting work
• Forklift operator licence (F endorsement) — required for forklift operation
• Scaffolding certificate — for scaffolding work above certain heights
• Confined Space entry training — for work in confined spaces

Step 4: Use a compliance gate at check-in

Manual compliance checks at the gate are inconsistent. On a busy site, the person responsible for checking induction records may be pulled away for other tasks. Under time pressure, checks get skipped.

A compliance gate in your site access system checks each person's status automatically when they check in with their QR pass. If their induction isn't complete, or a required certification has expired, they're flagged at the point of entry — not discovered after the fact.

Step 5: Maintain a live site occupancy record

At any point during the working day, you should be able to answer: who is on site right now? This matters for safety planning, for managing overlapping trades, and critically — for emergency evacuations.

A live occupancy record also provides an automatic audit trail. If WorkSafe asks when a particular contractor was on site, and what their compliance status was at the time, a digital system can produce that information instantly.

Step 6: Set re-induction rules

Compliance isn't a one-time event. Sites change, hazards evolve, and contractors who haven't been on site for an extended period may need refreshing. Common re-induction triggers include:

• More than 12 months since last visit
• Significant changes to site layout or hazard profile
• Contractor working in a new area of the site not covered by their original induction
• Following a near-miss or incident

Digital systems make re-induction easy to enforce — you can set an expiry period on induction records, so they automatically lapse after a defined time and require renewal before the contractor can check in again.
