Mr McArthur and his wife, Kaye, are right in the middle of the raspberry harvesting ''flush'', which began shortly after Christmas.
And they are employing more than 70 young people to help them with various parts of their business - about 60 involved in intensive raspberry picking.
Others help with other facets of the business, including in the packing house, and at the farm's sizeable roadside stall where products are sold direct to the public.
''It gives them a job''- in some cases their first work experience, Mr McArthur said of the young people.
And the raspberries urgently had to be picked.
Best picking conditions were when the sky remained a little cloudy, because on a scorching hot day it was sometimes too hot for picking to continue.
That was because the fruit became too soft and jam-like and workers sometimes had to stop work for health and safety reasons, he said.
Mr McArthur had several outlets for the latest raspberry crop, but the Otago Farmers Market remained a key place to sell his produce, he said.
He enjoyed selling through the Farmers Market, and liked the close connection he had built up with his customers over the years.
''It's good interaction, because they get to know the person who's growing it,'' he said.
He also enjoyed the banter with customers, and customers also liked hearing tips about how to prepare certain foods, he said.
