Meanwhile, its South American operations continue to be impacted by flooding in Uruguay earlier this year.
"While it remains early in the 2017 financial year, we have observed that the trading environment for agricultural inputs and services has become marginally more difficult in New Zealand," chief executive Mark Dewdney said.
"Additionally, we note the full effect of the flooding experienced earlier this year in South America still remains to be seen. For these reasons, we believe that 2017 will be a tougher trading environment than 2016.
"On the other side of the ledger, confidence in the horticulture and viticulture markets remains high and we see the diversification of our business as a real strength."
Dewdney said the company is currently tracking according to plan, but noted that the first quarter of the financial year is typically a quiet period.
