NZ's apprentice problem looks less like too few assessors and more like too few employers hosting apprentices, which starves learners of workplace practice and evidence. Simulated practicals can close part of that gap. But under current Waihanga Ara Rau guidance they belong on the training and practice side, not final assessment.
What is happening to NZ apprenticeship numbers?
They're falling, and fast. RNZ reported on 3 September 2026 that apprenticeship numbers had hit a 15-year low. Engineering and related technologies enrolments were down a third to 29,870. Architecture and Building was down 29% to 28,650. B2B News put the total at 108,315.
A Skills Group white paper, citing Ministry of Education figures, adds the completion picture:
- Total apprenticeships fell 14% between 2024 and 2025.
- New enrolments fell 24%.
- Only 40% of apprentices who started in 2021 completed within five years, against 54% of the 2016 cohort.
The paper calls for an overhaul, including degree apprenticeships and access to student loans and allowances.
Is assessment really the bottleneck?
Honest answer: nobody has shown that. We couldn't find an NZQA, TEC or Industry Skills Board source that names an "assessment bottleneck", or one that evaluates simulated practicals. Treat the phrase as an argument, not a finding.
There are indirect signals that physical practical assessment capacity is tight. Skills Trades' EWRB practical assessment listings show fixed campus intakes, and Stage 1 in Wellington on 2 November 2026 had three places left. EarnLearn requires at least 80% attendance from 2026 before a learner is eligible for assessment.
Both are provider signals, not independent studies. They show how assessment is scheduled, not that assessors are the scarce resource.
Why do fewer employers mean less evidence?
The stronger evidence points upstream. NEWS WIRE (September 2026) quotes BCITO's chief executive saying the shortage is of employers confident enough to sign apprentices up, with about 600 people ready to start. Q1 2026 enrolments were 11% below the same period a year earlier.
The sector gaps are large. B2B News, collating RNZ and industry quotes (check the originals before citing), reports:
- Master Electricians says 3,000–4,000 apprentices need to start each year, but only about 1,200 entered in 2025.
- Only 17% of plumbing businesses take on apprentices.
- The figure is 10–15% across construction.
The logic follows. Assessment needs evidence. Evidence comes from doing real work. Fewer hosts means fewer chances to do it, and that squeezes completion before an assessor ever turns up.
What do the rules say about simulation?
The guardrails are clear. Waihanga Ara Rau's June 2025 short course training and assessment guidance sets them out:
- A simulated environment must replicate the real workplace's environment, equipment and time or productivity pressures.
- Learners must be assessed in at least two different situations.
- Per its 26 June 2025 Q&A, a simulator is for training and practice, not assessment.
- Standard 25045 requires assessment in an actual workplace.
So a trade apprentice assessment simulation in NZ can't replace the workplace sign-off. It can change how prepared a learner is when they get there.
Where do simulated practicals fit?
There's precedent for flexibility. After COVID-19 and reform delays left more apprentices over duration, workplace assessment became a valid summative method in the plumbing, gasfitting and drainlaying model. Block courses also expanded from assessment only to teaching and practice. Waihanga Ara Rau's BCATS information for schools accepts skills achieved in school workshops and simulated workplace settings.
That points to a sensible division of labour:
- Before placement: build confidence and baseline competence, so an employer's first weeks with an apprentice are less of a gamble.
- Alongside placement: give apprentices repeated, coached practice on situations their job doesn't throw at them often, such as fault diagnosis, safety conversations and difficult customers.
- Between jobs: keep skills moving when work dries up or a host can't offer the full range.
- At assessment time: leave sign-off where Standard 25045 puts it, in the real workplace.
The fidelity test matters most. If a simulation can't reproduce the equipment, environment and time pressure of the real site, it fails the guidance. Scenario-based and coached formats, including AI-generated role plays, are strongest on the decision-making, communication and procedure side of trade work. They don't replace hands-on tool time.
Who can shape this next?
The audience for this argument is changing. Per the Ministry of Education, legislation passed in October 2025, and 10 regional polytechnics and 8 Industry Skills Boards became operational on 1 January 2026. Over two years, each Industry Skills Board will work out a future for apprenticeships and traineeships.
That's an opening. PTEs, polytechnics and employers who can show how simulated practice improved readiness have a chance to inform assessment policy while it's still open.
It's worth asking where your own bottleneck sits: in the assessor diary, or in the weeks before an apprentice has enough real practice to be assessed at all.
Key takeaways
- NZ apprenticeship numbers are at a 15-year low, and completion rates are declining.
- The best-supported constraint is employer willingness to host apprentices, not assessor numbers.
- No NZQA, TEC or Industry Skills Board source names an "assessment bottleneck", so it remains an argument.
- Under Waihanga Ara Rau guidance, simulators are for training and practice. Standard 25045 requires assessment in an actual workplace.
- Fidelity is the test: environment, equipment and time pressure must match the real workplace.
Our take
The sector is tempted to pitch simulation as a fix for assessment capacity. We think that's the wrong claim, and it won't survive scrutiny. The stronger case is that simulated practicals widen the supply of safe, repeated practice while workplaces are scarce, which should make each placement more productive for employer and apprentice. Providers who stay inside the guidance and measure readiness will be the ones the new Industry Skills Boards listen to.
FAQ
Can simulated practicals replace workplace assessment for NZ apprentices?
No. Waihanga Ara Rau's 26 June 2025 Q&A says a simulator is for training and practice, not assessment. It also says Standard 25045 requires assessment in an actual workplace.
What makes a simulated environment acceptable?
Per Waihanga Ara Rau's June 2025 guidance, it must replicate the real workplace's environment, equipment and time or productivity pressures. Learners must also be assessed in at least two different situations.
Is there an assessment bottleneck in NZ apprenticeships?
It isn't established. Provider listings suggest tight practical assessment places in some trades, but no NZQA, TEC or Industry Skills Board source we found names a bottleneck. The better-evidenced constraint is too few employers taking on apprentices.
Who decides future apprenticeship and assessment settings?
From 1 January 2026, 8 Industry Skills Boards and 10 regional polytechnics are operational. Over two years, each Industry Skills Board will work out a future for apprenticeships and traineeships in its industry.
