You quoted on a council earthworks package, submitted everything on time, and then got told you weren’t shortlisted. Not because of your price. Because your SiteWise score had lapsed. That single admin gap cost you the job before anyone even looked at your rates.

Understanding SiteWise prequalification NZ contractors rely on is now a baseline requirement — not a nice-to-have — if you want access to government, council, and tier-one principal work across New Zealand.
What Is SiteWise and How Does the NZ Contractor Score Actually Work?
When you’re back in the site office at 4pm finishing a daily diary, the last thing you want to think about is compliance admin. But SiteWise is exactly the kind of system that catches contractors off guard when they’re heads-down on delivery.
SiteWise is a third-party health and safety prequalification system operated by SiteSafe New Zealand. It assesses contractors against a standardised set of criteria and produces a score from 0 to 100. That score is used by principals — including NZTA, Kainga Ora, local councils, and large private developers — to decide which subcontractors they’ll let on site.
The scoring model evaluates your business across several dimensions: your health and safety management system documentation, incident history, worker competency records, and evidence of ongoing H&S activity. You submit documentation through the SiteWise portal, an assessor reviews it, and you receive a rating.
The four rating tiers work like this:
| Rating | Score Range | What It Means |
|---|---|---|
| Green | 60–74 | Meets baseline requirements for most work |
| Gold | 75–89 | Demonstrates a mature H&S system |
| Gold Plus | 90–100 | High-performance, used as differentiator on major contracts |
| No Rating / Lapsed | Below 60 or expired | Locked out of prequalified work |
Most principal contractors and councils set a minimum of Green. NZTA-funded work often requires Gold or above. If you’re sitting at 58 with an expired assessment, you’re not getting on the tender list — regardless of how good your track record actually is.

During Friday’s progress meeting with your foreman and site engineer, nobody’s talking about prequalification. But behind the scenes, the person who decides whether your company gets invited to quote next month’s package absolutely is.
SiteWise assesses contractors across five main categories. Knowing what these are lets you focus your effort where the points actually come from.
Step 1: Confirm your H&S policy is current and signed — assessors check that your policy is dated within the last 12 months and signed by a director or senior manager. An outdated signature is an instant deduction.
Step 2: Compile your hazard and risk register — this needs to reflect your actual trade work (excavation, concrete pours, crane lifts, confined space). Generic templates copied from the internet score poorly. Make it site-specific.
Step 3: Pull together your incident and near-miss records — SiteWise looks at your reporting culture, not just your stats. Showing a near-miss register with follow-up actions scores better than a blank sheet.
Step 4: Gather worker training and competency evidence — certifications (first aid, elevated work platform, traffic management supervisor), toolbox talk records, and induction logs all count here.
Step 5: Document your H&S monitoring activity — site inspection records, SWMS reviews, and management walkthroughs demonstrate that your system is live, not just a folder on a shelf.
Step 6: Submit through the portal and respond to assessor queries promptly — delays in responding to information requests can push your renewal past expiry, triggering a gap in your rating.
The categories aren’t equally weighted. Documentation quality and incident management carry the most points. Contractors who invest in structured SWMS templates and consistent induction records tend to score 10–15 points higher than those doing the same physical work with ad hoc paperwork.
Contractor Prequalification NZ: Why Principals Use SiteWise to Gate Tender Lists
At the 7am toolbox talk on a busy roading project, the principal’s H&S rep isn’t checking every subcontractor’s paperwork from scratch. They’ve already done that — weeks earlier, when they built the approved subcontractor register using SiteWise data.
From the principal’s side, SiteWise removes the burden of individually assessing every subbies’ H&S system. It’s outsourced verification. That’s why adoption has accelerated — it’s efficient for the buyer, and it shifts the compliance burden onto you.
Here’s the practical consequence: if your score lapses, you don’t get a phone call asking you to sort it out before the tender closes. You simply don’t appear on the shortlist. The project manager who’s worked with you for five years might not even know, because the tender portal filters automatically by prequalification status.
The sectors where this is now standard practice in New Zealand:
- NZTA and Waka Kotahi projects — Gold rating commonly required
- Kainga Ora and social housing — Green minimum, Gold preferred
- Local council civil works — Auckland Transport, Wellington City Council, Christchurch City Council all reference SiteWise
- Tier-one principals (Fletcher Construction, Fulton Hogan, Downer, HEB) — approved subcontractor registers tied to SiteWise status

The pricing to maintain your SiteWise registration sits around $400–$700 + GST per year depending on contractor size and trade category. Missing a renewal cycle because you were too busy on site to sort the paperwork is one of the most expensive admin mistakes a subcontractor can make.
SiteWise Green Gold Rating: What Separates a 68 From an 85
Halfway through a busy concrete pour on a commercial foundation package, your site supervisor isn’t thinking about the 17-point gap between your current Green rating and the Gold rating you need for that upcoming NZTA maintenance contract. You need to be thinking about it now, during the quiet periods between pours.
The difference between a Green and Gold SiteWise score isn’t usually a massive overhaul of your system. It’s typically three or four specific gaps in how you document what you’re already doing.
Common reasons contractors sit at Green instead of Gold:
- Toolbox talks are happening but aren’t being signed off and filed
- SWMS documents are generic, not task and site specific
- No documented management review of the H&S system in the past 12 months
- Incident investigations exist but don’t show corrective action closeout
- Worker competency records are incomplete or scattered across email threads
Use this template to audit your own scoring gaps before you engage an assessor:
SiteWise Self-Audit Checklist — [COMPANY NAME] | Trade: [CIVIL / CONCRETE / DRAINAGE / OTHER] | Date: [DD/MM/YYYY]
- H&S Policy — signed by director within last 12 months? Y / N
- Hazard register — trade-specific and reviewed in last 6 months? Y / N
- Incident register — includes near misses with corrective actions? Y / N
- Training records — all workers, certs current and filed? Y / N
- Toolbox talks — signed attendance sheets, last 3 months? Y / N
- SWMS — task-specific, not generic? Y / N
- Management H&S review — documented in last 12 months? Y / N
Score: Count your Y answers. 5–6: likely Green. 7: likely Gold territory. Under 5: renewal at risk.
If you’re using a tool like Donesafe (from ~$NZD 15/user/month — best for contractors with 10+ workers needing a full digital H&S platform) or Safety Champion (free tier available for up to 5 users — suited to small subcontractors getting started with digital H&S records), you can pull most of this evidence from your existing system without building new documents from scratch.
Health and Safety Prequalification Construction NZ: Keeping Your Rating Active Year-Round
When you get back to the site office at 4pm on a Monday after a site inspection, that’s the right moment to log your inspection record — not Friday afternoon when you’re trying to wrap up the week’s paperwork all at once.
The biggest threat to your SiteWise score isn’t a single bad incident. It’s drift. Gradual deterioration in the consistency of your H&S records until renewal comes around and you’re scrambling to reconstruct three months of toolbox talks from memory.
Here’s a structured approach to keeping your rating active without it becoming a full-time job:
SITEWISE MAINTENANCE SCHEDULE — [COMPANY NAME]
================================================
WEEKLY:
→ Toolbox talk completed + signed attendance filed
→ Near-miss log reviewed and updated
MONTHLY:
→ Site inspection completed + report filed
→ Incident register reviewed, corrective actions checked
→ Worker training register checked for expiring certs
QUARTERLY:
→ SWMS reviewed for current work types
→ Subcontractor H&S records audited
→ SiteWise portal checked — renewal date confirmed
ANNUALLY:
→ H&S Policy reviewed + re-signed by director
→ Full management review documented
→ SiteWise renewal submitted minimum 4 weeks before expiry
→ Competency register updated for all workers
Treat SiteWise like a compliance programme, not a one-off certificate. The contractors who consistently score Gold and above aren’t doing dramatically more than the Green-rated ones — they’re just doing it consistently and keeping the records to prove it.
Frequently Asked Questions
How much does SiteWise cost for NZ contractors?
SiteWise registration fees vary by contractor size and trade category, but most small to medium subcontractors pay between $400 and $700 + GST per year. There’s an initial assessment fee when you first register and an annual renewal fee. Some principal contractors will pay for or subsidise your SiteWise registration as part of their approved subcontractor onboarding — worth asking before you pay out of pocket.
How long does it take to get a SiteWise score in NZ?
From submitting your documentation to receiving your score, allow 2–4 weeks. If the assessor comes back with queries and you’re slow to respond, it can stretch to 6–8 weeks. Don’t start the process the week before a tender closes. Set a renewal reminder 8 weeks before your expiry date.
What happens if my SiteWise score lapses?
Your rating shows as expired in the SiteWise database, which is publicly searchable by principals. You’ll be filtered out of prequalified tender lists automatically. You can renew at any time, but there’s no grace period that keeps your old rating visible. Treat expiry as a hard stop — you’ll need to go through the full renewal process before you can be included in prequalified work again.
Can I improve my SiteWise score after an assessment?
Yes. You can request a reassessment once you’ve addressed the gaps an assessor identified. There’s typically a fee for reassessment. The most effective approach is to do a self-audit before your initial submission (use the checklist template above), so you’re submitting strong documentation the first time rather than patching gaps after a poor result.
What to Do Now
Your SiteWise score is a gatekeeper. It doesn’t matter how good your work is on site — if your rating is lapsed, under the minimum, or sitting at Green when the contract requires Gold, you won’t get the call.
The three things worth doing this week:
- Log into the SiteWise portal and check your current score and expiry date. If it’s within 8 weeks, start your renewal now.
- Run the self-audit checklist from this article. Identify which documentation gaps are dragging your score below where it should be.
- Set up a monthly maintenance routine — even 30 minutes a month filing toolbox talks and checking training records will keep your documentation in shape for renewal.
SiteWise isn’t complicated. It rewards contractors who do the basics consistently and keep the paperwork to prove it.
