DairyNZ’s latest contract milking insights were shared with farmers at recent joint events with Federated Farmers and FMG, providing useful context for the research.
Nine years of DairyNZ data show how contract milkers’ income and costs have changed over time. As farm owners lifted contract rates to match rising costs and inflation, both revenue and expenses increased. Even so, operating profit has remained steady, showing contract milkers have largely held their ground over the past decade (see graph 1).
Equity growth is strong too. After tax, farm costs and drawing a salary, the 100 contract milkers who enter their accounts into DairyBase grew their equity by an average of $42,900 during 2023/24.
“Contract milking is a simple structure, easy to understand and to budget for, and is a good introduction to business,” says DairyNZ business specialist Sarah Brown.
A DairyNZ study found five key factors determine whether a contract milker will be successful.
Firstly, a contract-milking agreement must be financially viable for both the contract milker and the farm owner.
“Contract milking is a business partnership — not an employment arrangement. Both the farm owner and the contract milker need to benefit from the agreement for it to be successful,” explains DairyNZ senior business specialist Paul Bird.
“And because of the extra pressure, responsibility and risk they take on, the contract must also be profitable for the contract milker.”
It’s also crucial that the contract’s requirements are fully understood, with each party completing their due diligence and seeking independent legal advice.
“Every clause in the contract needs to be carefully reviewed to ensure it’s practical and achievable,” says Paul.
It’s also vital for the contract milker and farm owner to share and understand each other’s goals and farm philosophies. For example, if the farm owner follows a low-input philosophy, but the contract milker is passionate about supplementing feed to boost production, the two philosophies are likely to clash.
Paul says a successful contract milker needs a well-rounded skill set combining strong grazing and feed management with solid financial and people management skills.
"Building equity matters, focussing on profit, managing drawings, and steadily improving the business are important factors that contribute to a successful contract milking business.”

And ultimately, both parties must want the other one to succeed; they must have a win-win mindset.
Farms performing in the top 25% for equity growth have a combination of higher profit per kg milksolid and lower drawings from the business. Limiting drawings supports equity growth by allowing consistent reinvestment of profits, alongside careful management of farm working expenses.
Contract milking remains a valuable pathway for farmers, particularly when paired with the right skills, a robust contract, and strong financial management.
Even smaller herds – under 300 cows – can deliver strong equity growth when contracts are well structured and expenses are carefully managed, Sarah points out.
“There are tools, courses and support available to make contract milking a viable pathway to advance and build wealth in New Zealand,” says Sarah.

“The contract milking calculator allows both farm owner and contract milker to sit down together to discuss actual cash and non-cash costs and ensure our contract milkers are earning a premium over and above what a manager should earn for the same job.”
