OVERSEER: great farming backed by science 

OVERSEER is New Zealand software that enables farmers and growers to improve nutrient use on farms, delivering better environmental outcomes and better farm profitability. 
First developed in the 1980s, OVERSEER is now an essential farming tool, founded on decades of scientific investment.

Some of these photos were supplied by the Fertiliser Association of New Zealand and AgResearch Limited.

What's New

New Overseer FM software to be launched soon

Our new Overseer Farm Modelling (Overseer FM) is on track for release in the next few weeks. The new software is much more user friendly, and will deliver results that are more useful for both farmers and regulators.
We've made the changes following extensive consultation with the sector, with the ambition to ensure Overseer meets your changing needs and can continue to support great farming decisions grounded in science. More information soon.

OVERSEER version 6.3.0 has been released, providing performance, modelling and data entry improvements and the addition of Outdoor Pigs.
