New Zealand farmers have more than two years to prepare for two Approved Codes of Practice (ACOPs) that come into effect on 1 April 2027, alongside amendments to the Health and Safety at Work Act that take force on the same date.

Workplace Relations and Safety Minister Brooke van Velden launched the codes this week. The first, Roles and Responsibilities in Agriculture, targets the messy reality of farm work where multiple parties hold overlapping health and safety duties. It sets out who does what among farmers, managers, workers, contractors and suppliers.

The second, Safe Farm Vehicle Operation, tackles vehicle-related risks — a persistent killer on New Zealand farms. It covers choosing the right vehicle for the job, checking conditions before work begins, reassessing risks when circumstances change, and keeping people clear of moving machinery.

Why the timing matters

The 1 April 2027 date is not arbitrary. The same day brings into force amendments to the Health and Safety at Work Act that clarify responsibilities for recreational activities on farm land, sharpen duties for directors, and reduce the compliance burden on small businesses. Launching the ACOPs now gives the agriculture sector a runway to understand and apply the guidance before the legislative changes bite.

For farm businesses, the practical value lies in the safe-harbour provision. After 1 April 2027, WorkSafe may grant the ACOPs safe-harbour status, meaning a business that follows the codes' recommended actions has sufficient evidence it has met its legal duty. That status is not automatic — the Minister for Workplace Relations and Safety would need to reapprove each ACOP following consultation before it applies.

Until then, the codes function as a recognised compliance standard rather than a mandate. Compliance with an ACOP remains voluntary.

What the codes cover in practice

Van Velden stressed the codes create no new legal duties. Instead, they clarify existing ones — who needs to do what, where responsibilities overlap, and how serious risks should be managed.

"Farm work often happens in changing environments, with different people and businesses working together," the Minister said. "Developed with input from the agriculture sector, the ACOPs use practical examples that reflect how farms operate day to day, including before work starts, when bringing contractors onto farm, when choosing or using farm vehicles, and when conditions change."

That sector input matters for implementation. The examples track real decision points: a contractor arriving on farm, a vehicle choice for a particular task, a change in weather or ground conditions mid-job. Farmers who build these checkpoints into routine planning will find the codes workable rather than bureaucratic.

WorkSafe will work with industry to help businesses understand and apply the ACOPs in day-to-day operations, the Minister confirmed.

What farmers should watch

The immediate task for farm owners and managers is straightforward: read both codes, map them against current on-farm practice, and identify gaps — particularly around contractor inductions and vehicle selection. Businesses that already run documented vehicle checks and contractor briefings will find much of the ground familiar.

The bigger question is the safe-harbour decision. A consultation on reapproving the ACOPs for safe-harbour status will follow before the April 2027 commencement, and the outcome determines whether following the codes amounts to full legal protection or simply good practice. Farmers and industry bodies should watch for that consultation and the final WorkSafe guidance on how inspectors will treat ACOP compliance after the new law takes effect.

Both codes are available now on the WorkSafe website: Roles and responsibilities in agriculture and Safe farm vehicle operation.
