"We started the programme with 18 brands that recognised their responsibility to provide a long-term solution for their products' packaging when the farmer or contractor had finished with it," she said.
"Not only has that number grown to 65 brands, but we've also added large drum recovery and chemical collection."

Ms Wilcox said a buried 20-litre container would take more than 400 years to break down, while burning it released harmful dioxins and furans into the air and soil.
Recycling it saved energy equivalent to two litres of petrol.
"It's a bit of no brainer, as some of our recyclers like to say," she said, adding that what was acceptable practice in the past would not be acceptable in the future: "We have to find ethical ways of dealing with farm waste that line up with the demands of our export markets, and with farmers' desire to be good stewards of their land."
- Canterbury was leading the way, with 325,574 containers and 22,600 litres of chemicals surrendered to Agrecovery over the last 10 years. Northland ranked 13th out of 15 regions, with 22,443 containers and 890 litres.
