The new contractor “gateway test” (in force from 21 February 2026) is designed to give more certainty when the arrangement clearly looks and behaves like contracting from the start. If the arrangement doesn’t meet the gateway criteria, it doesn’t automatically become employment — it just means you fall back on the usual “real nature of the relationship” assessment.
DOES A TYPICAL NEW ZEALAND CONTRACT MILKING AGREEMENT STACK IP AS A GENUINE CONTRACTOR ARRANGEMENT?
Generally: yes — contract milking usually has strong contractor features (it’s a self-employed, performance-based model where the contractor runs labour and carries business costs/risk).
But whether it really stacks up legally depends on two things:
What the contract says, and
What actually happens day to day on farm (this is the big one).
HOW CONTRACT MILKING IN NEW ZEALAND MEASURES UP AGAINS THE KEY CONTRACTOR INDICATORS:
A written contractor agreement
Most contract milking arrangements do have a clear written agreement stating it is contracting, not employment. That’s a strong start.
Tip: a signed agreement helps, but it won’t save you if the reality looks like employment.
Control over how and when the work is done
This is often mixed.
Contract milkers usually have autonomy over:
staffing and rostering
day-to-day decisions and priorities
how work is organised to meet farm outcomes
Where it can get wobbly is when the farm owner starts running the contractor like an employee, for example:
dictating daily hours/finish times
approving “leave” and/or “suitable replacements” in the contractor’s absence
directing step-by-step methods for routine tasks
requiring timesheets like wages
constant day-to-day instruction rather than outcome expectations
Best practice: owners set outcomes, standards and compliance requirements (animal welfare, milk quality, health & safety, reporting), but avoid “employee-style” direction and control.
Ability to work for other clients
This is the hardest gateway-test factor for contract milking in the real world. In practice, many contract milkers:
are effectively tied to one farm for the season, and/or
have terms (or expectations) that discourage outside work
Even if a contractor wouldn’t realistically do other work, it helps if the agreement and behaviour don’t treat them as exclusive “staff”.
Best practice: allow outside work unless there’s a genuine issue (fatigue/safety, conflict of interest, confidentiality, performance).
Supplying tools/equipment
This is usually partly yes. Contract milkers typically provide some of their own business tools (vehicles/phones/admin systems, sometimes bikes or gear), and they cover certain operating costs. But the farm owner supplies the core assets (farm, cows, plant) — that’s normal in dairy.
Best practice: clearly define who supplies what, and make sure real life matches that.
Business risk and invoicing
This is one of the strongest contractor signals for contract milking.
Common contractor features include:
payment linked to performance (e.g., $/kgMS)
contractor paying defined operating costs
contractor invoicing (and often GST registered where appropriate)
contractor carrying business insurances/ACC obligations
contractor employing or engaging staff themselves and carrying those obligations
The more “real business risk” the contractor carries, the stronger the contractor positioning tends to be.
The two biggest risk areas are control and exclusivity. A contract milking arrangement can start to look less like contracting, and more like employment, if the owner begins setting hours, approving leave, rostering shifts, or directing routine work too closely. Exclusivity can also weaken the contractor position if the milker is effectively treated as unable to do other work.
For contract milking to remain a genuine contractor model, it needs to operate like one in practice. That means real autonomy, clear commercial responsibilities, and an owner focus on standards and outcomes rather than employee-style management. Any restrictions on outside work should be reasonable and linked to genuine business concerns. In the end, what happens day to day on farm matters most.
