"There's a lot of stops and starts, so it's probably about four hours all up."
The Agria potatoes, which were left with a contact phone number, were well received.
Collins estimated they received about 70 thank-you texts and 50 phone calls.
As far as he is concerned, it is just something the family can do for their community - and a couple of tonnes of Agria potatoes out of a yield of about 1000 tonnes does not make too much of a dent.
Pareora born and bred, Collins went to school in the township before making a start in farming as a young man.
"I started off growing spuds. I was only a kid, with no money, so I went around farmers and asked for their roadsides. That's where I started, and now we own 1000ha. We've bought out the valley."
A big part of the Dalmore Farm operation is now a 1200-head herd of dairy cows, but Collins says he is not ready to give up the potatoes completely - 100ha is now about 20ha but he is not sure there will come a day there are none on the property.
"I've just about finished growing spuds, but it's a bit of a disease with me. I've grown them for 60 years."
