An independent study completed by agribusiness analysts Nimmo-Bell & Company Ltd has estimated that NDDT and NARF have contributed over $300 million to the Northland economy. Six projects were assessed including the Split Calving trial conducted in the late 1990s, the Endophyte, Mastitis, Nitrogen and Stand Off Pad trials, and the recently completed Kikuyu trial.

The total net benefit from increased productivity after allowing for the costs of the research is $315.1 million. This represents a net benefit ratio of $76 for every dollar spent and an average return of $162 per ha per year across Northland dairy farms.

The benefits were only assessed north of Auckland however the impact of the split calving and kikuyu work in particular further south has also been significant and is not included in these figures.
