Paying the dairy sector's share of the biosecurity readiness and response costs.

In October and November 2025, DairyNZ levy payers voted in support of a proposal to expand the Biosecurity (Response - Milksolids Levy) Order 2019 to include biosecurity readiness activities, as well as response.

This will help strengthen on farm protection by preparing for major biosecurity threats before they occur and support DairyNZ’s commitments under the Government Industry Agreement (GIA). This change represents a step towards consolidating the multiple biosecurity levies that dairy farmers pay and creating an integrated, science-based, sustainably funded biosecurity system.

The application to amend the levy has been approved by the Minister and changes are being drafted. They are expected to take effect in early 2027.

Mycoplasma bovis (M. bovis) response funding held in reserve will be unlocked so it can be used to fund biosecurity readiness as well as for response, making use of the investment farmers have already made.  

Investment in biosecurity readiness will be capped at 82% of the M. bovis response reserves to reflect the proportion of levy payers who did not oppose using the reserve funding to strengthen the sector’s biosecurity preparedness for a large response like FMD.

The Biosecurity Response Levy rate is currently 0 cents /kg milksolids and the new levy will remain the same.

On 1 January 2025 the Biosecurity Response Levy (which previously paid for the M. bovis response) was reduced from 0.8 cents to 0 cents per kilogram of milksolids. This reflects the progress made to eradicate M. bovis as it transitioned to a National Pest Management Plan (NPMP).

The Biosecurity Response Levy rate is set each year and is communicated to farmers in writing in advance of the effective date.

The levy collection is administered by milk supply companies, which is passed on to DairyNZ for supporting response and soon to be readiness activities.

History of the Biosecurity Response Levy

In February 2019, we consulted with farmers about the establishment of the Biosecurity Response Levy to fund the dairy farmer’s share of biosecurity responses like FMD and the M. bovis programme before it transitioned to pest management.

Farmers told us they wanted the levy to be managed by DairyNZ and supported the cap (maximum rate) being set at 3.9 cents per kilogram of Milksolids per year.

With DairyNZ managing the Biosecurity Response Levy on your behalf, it gives dairy farmers a voice, and DairyNZ a seat at the decision-making table for biosecurity preparedness and responses to help your voice be heard.

Questions and answers about the Biosecurity Response Levy

Could the Biosecurity Response Levy rate increase again?

Yes, but only in the event of a future biosecurity response that significantly impacts on the dairy industry and farmers and uses up all the reserves. Farmers will be notified of any future change.

Is the biosecurity response levy separate to the DairyNZ Milksolids levy?

Yes this is a separate levy, managed by DairyNZ to fund dairy industry biosecurity commitments under the Government Industry Agreement (GIA).

The change to the Biosecurity Response Levy will “free up” some commodity levy funding to support other strategic DairyNZ priorities, while reducing the need for farmers to invest in another levy in the short term.

What assurance can you provide that the biosecurity levy will be put towards readiness and response and not used up in ‘admin’ expenses?

The levy will be used to pay dairy farmer’s share of readiness activities and response costs after they are incurred. By DairyNZ managing the levy, farmers get more assurance that it will be spent on effective readiness and response activities, as by signing up to GIA we have a seat at the decision-making table on what is invested in biosecurity readiness and response. We will let farmers know each year what the levy will be and what it has been spent on.

Questions and answers about the Government Industry Agreement (GIA)

Why did DairyNZ sign us up to GIA in the first place?

There is always the risk of unwanted pests and diseases making their way into New Zealand and significantly affecting dairy farming. The GIA commits industry and government to work together in partnership to jointly improve readiness for future biosecurity events and respond effectively to future outbreaks. By working together, we can be better prepared at immediately finding new arrivals, responding fast, and as such reduce the damage from incursions.

DairyNZ has leveraged significant Government funding in this partnership, with Government funding 68% of the M. bovis response programme. Through the GIA we can get agreed contributions from Government taxpayer money to fund biosecurity response activities.

In June 2025, DairyNZ signed the Foot and Mouth Disease Operational Agreement (FMDOA), formalising our co-leadership in national readiness for FMD. This milestone strengthens New Zealand’s biosecurity system and highlights the importance of funding readiness activities for threats like FMD, avian influenza, and lumpy skin disease. Biosecurity is a key priority for DairyNZ as it helps to power more adaptable and resilient farms – with dairy farmers the biggest sector investors in the biosecurity system.

By signing up to GIA we have a seat at the decision-making table in setting biosecurity priorities. Non-GIA signatory beneficiaries are going to still be required to pay, but they won’t have any decision-making rights.

Could non-signatories to GIA walk away from a response and not have to pay anything?

There are currently 26 GIA signatories including MPI, and all the significant animal and horticulture sectors have joined. MPI is looking at the policy and regulatory framework needed so that non-GIA signatory beneficiaries will be paying their share, but they won’t have any decision-making rights.

The bottom line is industry will need to contribute to biosecurity responses, either by MPI requiring those that haven't signed up to GIA to pay their share if they benefit from the response or through negotiation of crown/industry funding proportion through a GIA operational agreement. Industry stands to get a better deal through the GIA route and better opportunities to influence a positive outcome of the response.

Is the DairyNZ Board entering into commitments where there could be liability issues because we can’t pay? If we can’t pay does GIA fall over?

The DairyNZ Board has and will be prudent in only entering into commitments that can be funded within the levy maximum set under regulation. DairyNZ on your behalf, decides what we will sign up for and whether we are beneficiaries of any response. We then negotiate with Government and other sector beneficiaries on fair and equitable cost shares specific to the response. The DairyNZ Board makes sure that liability is limited before we sign up to any funding commitment.

Questions and answers about the Mycoplasma bovis Response

Why is there a funding reserve from M. bovis and how much is it?

Prior to the transition of the M. bovis response to pest management, a significant amount of compensation was expected to be claimed for projected losses as a result of response activities. At the time DairyNZ collected levy funds in the event we were liable to pay for the dairy industry share of these compensation claims, some of which are still being resolved. This resulted in the collection of a funding reserve, which is now deemed unlikely to be fully needed to cover significant outstanding compensation claims. As of 31 May 2025, the balance of the reserve available for future compensation payments was $15,178,551.

Any funds not needed for M. bovis compensation claims can only be used in the event of a future biosecurity response that impacts the dairy industry. Under the current Biosecurity Levy Order, it is not possible for DairyNZ to simply repurpose these funds without consulting farmers.

Why is money still collected for M. bovis if there is a funding reserve?

With transition of the M. bovis response to a national pest management plan, a new levy was required to fund the remainder of the eradication programme. With the progression of the programme out of the response phase and into pest management, legally the Biosecurity Response Levy could no longer be used. This is an example of why biosecurity levies from M. bovis, TB and NAIT should be reviewed. From 1 January 2025, the remainder of the dairy industry share of the M. bovis programme is paid for by the M. bovis NPMP levy, which was set at 0.4c/kg MS from 1 October 2025.
