Most businesses that use container unloading services end up at the same arrangement. They find a provider, agree on an hourly rate, and assume that is the sensible way to buy the service. The hours go in, the container gets cleared, the invoice arrives.
The logic seems sound. It is also costing more than it should.
When you pay by the hour, you are paying for time. That much is obvious. What is less obvious is that you are also paying for a model where slowing down is financially rational for the worker.
A container unloading crew that clears a container in three hours takes home three hours of pay. A crew that stretches the same job to five hours earns nearly double. There is no malice in this. The structure produces the outcome whether anyone intends it or not.
This is the incentive misalignment at the heart of most casual devanning arrangements in New Zealand and Australia. The worker is paid for attendance, not output. The business absorbs the cost.
And the cost is not just the extra labour. If your container sits at the dock longer than planned, transport detention charges apply, typically $80 to $120 per hour in the Australian market. Carrier storage fees can add another $100 to $250 per container per day once free time expires. A container unloading job that runs from three hours to five and a half does not just cost two and a half hours of extra crew time. It can cost several times that once the downstream charges land.
Paying a fixed rate per container changes the structure of the incentive.
When the price is set in advance, fast, clean work is in the crew's direct interest. Every unnecessary hour is time they are not earning on the next job. The model rewards the outcome, not the time spent on site.
The effect is clearer still when a fixed-rate contract is paired with a piece-rate crew incentive system. The crew earn more when the job is done well and done quickly. The business pays a known amount and gets a predictable result.

A well-run three-person container unloading crew, working to a fixed-rate model, will consistently clear a standard 40-foot container loaded with 2,500 cartons in around three hours. Two workers in the box, one on the forklift, five SKUs or fewer, no unusual staging requirements.
The same job contracted on a casual hourly basis at Australian labour hire charge-out rates of $38 to $58 per hour commonly runs to five and a half hours or more. That gap, across one job, is $76 to $145 in direct labour cost before any detention or dock downtime is counted. Across a year of regular container unloading, that differential compounds quickly.
The numbers are similar in New Zealand, where warehouse labour hire on-costs follow the same structure even if the base rates differ.
Container unloading pricing in New Zealand is often presented as a fixed rate when it is not. Some providers offer a nominal container rate with hourly variations built in for wait time, cargo weight, SKU count, or crew size adjustments. These are not fixed rates. They are hourly models with a fixed-looking wrapper.
The question to ask any devanning provider is straightforward: what is the total price for this container, and under what conditions does that price change?
A provider who can answer that clearly and specifically, without a list of conditions, is running a genuine fixed-rate model. A provider who gives you several caveats is, in practice, billing by the hour.
Oak Tree pioneered the fixed-rate-per-container model in New Zealand in 2002. At the time, most container devanning was contracted on hourly rates. That model is still how we operate today, across Christchurch, Auckland, and Australia.
Around 80 per cent of our crew face real barriers to steady employment. The incentive model is part of why they stay, show up, and take the work seriously.
