While the farm was not organic, the majority of the growing process was done the use of chemicals.
"This is not a spray-and-pray operation. There is no guessing for us — we know exactly what the chemistry of our soil is and people can see how passionate and authentic we are about what we do".
Grown on peat, the bushes were managed year-round by horticulture experts and seven frost-fighting fans to keep temperatures stable for optimal growth.
Owned and operated by the Furniss Family, Blueberry Country was established about 30 years ago in Ohaupo, Waikato, with two farms in Ohaupo and Ngatea.
The family then bought the Southland land where the farm is now located 15 years ago.
The Otautau farm employed 70-80 commercial pickers each season — the majority from overseas on seasonal work visas Bardon said.
"A lot of people don't know we exist here in Southland.
"We can have blueberries picked, processed, packaged and delivered to supermarkets in 36 hours during the season".
In the on-site grading house, each berry is tested for colour, size, texture and blemishes by state-of-the-art technology before being packaged.
Bushes which were not hand-picked this season, would be machine harvested and frozen for sale.
Although the company was New Zealand's largest blueberry grower in production, the Southland orchard was still expanding, he said.
"It's a developmental orchard, we still have 40 per cent of our acreage in grass, but it's grass in production".
While it was "a very long way off" being a fully productive unit, he was optimistic about its future.
