NZ contractor evidence guide

What health & safety evidence should an NZ contractor be able to produce?

Clients do not all ask for exactly the same documents. But there are recurring evidence areas worth keeping organised so you are not starting from scratch every time you tender or onboard with a new client.

The principle: evidence should match the work and its risks. WorkSafe says the amount of information requested from a contractor should be proportionate to the size, complexity and risk of the work.

Core evidence areas

1. Risk and hazard management

Records identifying significant work risks, the controls used, and job- or site-specific planning where appropriate.

2. Training and competency

Relevant qualifications, licences, certificates, training, experience or competency records for people carrying out the work.

3. Worker information and engagement

Induction records, toolbox talks, meeting notes, consultation records or other evidence showing how workers receive information and participate in H&S.

4. Incident and near-miss management

Incident records, investigations where appropriate, lessons learned and evidence that corrective or preventive actions are followed through.

5. Inspections and monitoring

Completed workplace, plant or equipment checks relevant to your operation, plus evidence that issues identified are dealt with.

6. Plant, equipment and substances

Where relevant, maintenance, inspection, certification, safety data sheets or other records supporting safe use.

7. Subcontractor and PCBU coordination

If you work alongside or engage other businesses, keep practical evidence showing how risks, responsibilities and changes are communicated and coordinated.

8. Evidence organisation

An index showing what evidence exists, where it is stored, who owns it and when it was last reviewed can save considerable time when a client asks for information.

Current evidence matters

Do not assume an old document is useful simply because it exists. Some assessment schemes have explicit currency requirements. SiteWise's current Contractor NZ guidance, for example, states that evidence submitted for its assessment generally needs to be less than 12 months old. Always use the requirements of the actual client or scheme you are dealing with.

Don't confuse evidence readiness with certification

Having organised records does not certify a business, guarantee legal compliance or guarantee acceptance by a client or prequalification provider. It simply puts you in a better position to respond accurately when information is requested.
