Dairy farmers are celebrating - as the sector delivers a record year. 

Data from Dairy NZ's annual state of the dairy nation report, shows farmers produced an unprecedented 21 billion litres of milk in the 2024/2025 season. 

It's also brought the highest ever export earnings worth 27.1 billion dollars. 

Federated Farmers Dairy Chair Karl Dean told Ryan Bridge a lot of it comes down to herd testing to ensure Kiwi cows have the best genetics. 

He says as performance and profitability continue to increase - the Government gets more tax revenue.
