Horticulture and packhouse safety: managing seasonal peaks safely

What makes packhouse safety uniquely challenging

A packhouse shares many features with a warehouse or manufacturing facility, but it operates under conditions that amplify the risk in ways specific to horticulture.

The seasonal surge

The defining challenge of packhouse safety is the speed at which operations scale up and down. A kiwifruit packhouse in the Bay of Plenty might run a skeleton crew for months, then ramp to hundreds of workers within weeks when harvest begins. That sudden scaling brings more forklifts, more pedestrians, more product movement, and more pressure, all at once.

WorkSafe has explicitly noted that harvest season brings heightened risks from more product movement, less space to work, and more people in close quarters. The volume of fruit or vegetables flowing through the facility during peak season means forklifts are constantly moving bins between receival, grading, packing, coolstore, and dispatch. The physical space doesn't change, but the intensity of activity within it increases dramatically.

Forklifts in a fast-changing environment

Forklifts are the workhorses of any packhouse operation. They move bulk bins from the orchard to receival, shift pallets between processing stages, and load trucks for dispatch. During peak season, forklift movements multiply, and the areas where vehicles and pedestrians interact become more congested.

The consequences can be severe. In recent years, a worker at a major Bay of Plenty kiwifruit packhouse lost his lower leg after being struck by a reversing forklift. The incident led to an enforceable undertaking with WorkSafe worth more than $500,000, including fitting AI pedestrian detection systems to the packhouse's forklift fleet and collaborating with the wider kiwifruit industry to improve safety technology uptake.

WorkSafe's response underscored the point: the risk isn't theoretical. When forklifts and pedestrians share space in a busy packhouse, serious injuries happen.

Machinery and processing lines

Packhouse processing equipment, including grading lines, conveyors, sorting tables, bin tippers, and balers, involves moving parts that can cause serious harm. WorkSafe's 2025 horticulture assessments found significant gaps in machine guarding across the sector, and the regulator has noted that machinery accidents are a common cause of acute harm in manufacturing environments, which includes packhouses.

In late 2025, a worker at a Bay of Plenty kiwifruit packhouse was critically injured while cleaning a conveyor system. WorkSafe's investigation found poor safeguarding and inadequate risk assessment, and issued a prohibition notice requiring safety improvements before the equipment could be used again.

These incidents highlight a pattern: the most serious machinery injuries often occur during non-routine tasks like cleaning, maintenance, and changeovers, the moments when guards may be removed or bypassed and workers interact directly with equipment.

The seasonal workforce challenge

Packhouses rely heavily on seasonal and temporary workers, many of whom may be new to the site, unfamiliar with the specific equipment, or working in New Zealand for the first time. WorkSafe has specifically stated that seasonal workers are just as entitled to health and safety protection as year-round staff, and that they are at greater risk of workplace harm.

Language barriers can compound the problem. When safety training, signage, and on-the-job communication aren't accessible to workers with limited English, the gap between what procedures require and what actually happens on the floor widens.

Hazardous substances

Packhouses use a range of chemicals for post-harvest treatment, sanitation, and pest management. WorkSafe's 2025 assessments found chemical management to be one of the areas where the sector most needs improvement, including issues with incompatible chemical storage, signage, and compliance with the Health and Safety at Work (Hazardous Substances) Regulations 2017.

Where traditional safety approaches struggle during peak

Most packhouse operators have safety management systems: inductions, toolbox talks, PPE requirements, traffic management plans, and machine guarding. These work reasonably well during the off-season when the permanent team is smaller and operations are less intense.

The challenge is maintaining the same level of compliance when the operation scales up for harvest. Suddenly there are three times as many people on site, many of them new. Forklifts are running longer hours. Processing lines are at full capacity. The loading dock is busier than it's been all year. And the supervisors who managed safety effectively with a smaller team are now stretched across a much larger, faster operation.

Near misses, the leading indicators that predict future incidents, are least likely to be reported during the busiest period, precisely when they're most likely to occur.

How computer vision AI helps manage peak season safely

Computer vision AI uses your existing CCTV cameras to continuously monitor the packhouse during the periods when risk is highest and traditional oversight is most stretched.

What it detects

In a packhouse, the most critical detections include pedestrian-forklift near misses across receival, processing, coolstore, and dispatch zones, exclusion zone breaches near processing equipment, bin tippers, and restricted areas, vehicle speed violations during peak throughput periods, and patterns in how people and vehicles move through the facility as the operation scales up.

The system focuses on your highest-risk zones rather than requiring coverage of every camera on site. In a packhouse, those zones are typically the receival area where bins arrive from the orchard, the main forklift thoroughfares between processing stages, the dispatch dock, and the intersections where vehicle and pedestrian traffic cross.

Seeing how peak season changes your risk profile

The heatmap and reporting tools aggregate safety events over time, showing exactly how your risk profile changes as the operation scales up. You might discover that near-miss rates at the receival dock triple in the first week of harvest as forklift movements increase. Or that a particular intersection near the coolstore becomes significantly more dangerous during the afternoon shift when dispatch activity peaks. Or that a pedestrian route that's safe during the off-season becomes a high-risk zone when seasonal workers take a shortcut to avoid a longer walk around the processing area.

These patterns are invisible without continuous monitoring, but once you can see them, you can act on them: adjust a traffic route, add a temporary barrier, stagger a receival schedule, or brief the team on a specific risk zone during toolbox talks.

From detection to coaching

Every captured safety event becomes the starting point for a coaching conversation. Video clips with faces blurred for privacy are shared with the team: what happened, what could have gone wrong, and what should change.

In a packhouse with a large seasonal workforce, this coaching approach is especially valuable. New workers learn from real events that happened on their actual site, not abstract training scenarios from a generic induction video. The visual nature of the coaching also helps bridge language barriers, because you can see what happened regardless of the language you speak.

inviol customers typically see an average 67% reduction in risk and a 42% reduction in incidents across their sites.

Compliance and your obligations

Under New Zealand's Health and Safety at Work Act (HSWA), PCBUs must eliminate or minimise risks so far as is reasonably practicable. WorkSafe has made clear that this duty applies equally during peak season, and that seasonal workers deserve the same level of protection as permanent staff. A system that continuously monitors your highest-risk zones and documents how safety events are identified, coached, and resolved provides strong evidence of meeting your duty of care, particularly during the periods when your operation is at its most intense.

In Australia, Safe Work Australia reports that agriculture, forestry and fishing has the highest fatality rate of any industry at 13.7 per 100,000 workers, and the model WHS laws require the same standard of risk management during seasonal peaks as at any other time.

Getting started

If you operate a packhouse, the best time to implement continuous monitoring is before your next peak season begins. Start by identifying the zones where forklift and pedestrian traffic will most intensely overlap when operations scale up. Computer vision AI works with your existing CCTV cameras, processes data on-premise for privacy, and gives your safety team the visibility they need during the periods when risk is highest.

Frequently Asked Questions

What are the biggest safety risks in a packhouse?

The biggest risks include forklift-pedestrian interactions during peak season when vehicle movements multiply, machinery injuries from processing equipment like conveyors, graders, and bin tippers (especially during cleaning and maintenance), hazardous substance exposure from post-harvest chemicals, and the additional risk created by seasonal workers who may be unfamiliar with the site.

Why is peak season more dangerous in a packhouse?

During harvest, packhouses scale up rapidly: more workers, more forklifts, more product movement, and more time pressure. The physical space doesn't change but the intensity of activity increases dramatically. Near misses are most likely to occur during peak season and least likely to be reported, because everyone is busy.

How does AI help manage safety during seasonal peaks?

Computer vision AI uses existing CCTV cameras to continuously monitor high-risk zones during the exact periods when traditional oversight is most stretched. It captures forklift-pedestrian near misses, exclusion zone breaches, and speed violations across every shift, and generates heatmaps showing how the risk profile changes as operations scale up.

Are packhouse operators responsible for seasonal worker safety?

Yes. Under HSWA, PCBUs must ensure the health and safety of all workers, including seasonal and temporary staff. WorkSafe has explicitly stated that seasonal workers are just as entitled to safety protection as permanent staff, and has taken enforcement action against packhouse operators who fail to meet this standard.

Does coaching help with language barriers in a diverse seasonal workforce?

Yes. The coaching approach uses video clips of real safety events captured on site, with faces blurred for privacy. Because the events are visual, workers can understand what happened and discuss how to prevent it regardless of their language background. This makes the coaching more effective than text-based training materials for a diverse workforce.
