Bay of Plenty farmers and horticulture growers may be able to get rid of chemicals for free through Agrecovery's Rural Recycling upcoming collection.
Jason Richards from Agrecovery said it was able to provide the service largely free of charge, due to the financial support of its 64 manufacturers and distributors.
"While we can't guarantee all booked chemicals will be free or subsidised, our funding tends to cover the majority of bookings."
In 2014-15 financial year, more than 1500 kilograms of agrichemicals were collected from Bay of Plenty, making up about 10 per cent of the national volume, he said.
"Despite the large volumes collected over the years, we know there are still properties with unwanted chemicals.
