The call comes after Bodo Lang, a University of Auckland marketing professor, slammed milk pricing in New Zealand as "astoundingly high".
Federated Farmers dairy chairman Chris Lewis told The New Zealand Herald he avoids the supermarket altogether when buying milk for his family.
Instead he buys two 2-litre bottles of milk for $6 from his local Waikato dairy.
Mr Lewis questions what goes on between the product leaving the farm and entering the supermarket for the prices to be quite as high as they are at present. He said farmers got about 60c per litre of milk sold.
A Foodstuffs spokeswoman said retail prices took into account the wholesale cost from suppliers, which could change according to the price they could achieve on the global market.
"Then we add our own costs, which include but are not limited to wages, salaries, transport, refrigeration, taxes etc," she said.
"We aim to be competitive and try to ensure this fridge staple is as affordable as possible for New Zealand households."
Dr Lang referred to a recent trip to Europe and the shocking price comparisons on dairy products there.
In Germany for instance, he discovered that a litre of fresh milk was selling for the equivalent of $1.51, compared with $2.37 in New Zealand.
When the Herald looked at prices of a 2-litre bottle of milk at the big supermarket chains on Monday, the range was between $3.45 and $6.79.
Foodstuffs said economies of scale, population size, subsidies, different production methods, welfare standards, tariffs, wage rates and employment conditions, exchange rates and GST equivalents needed to be taken into account when looking at prices overseas.
The majority of shoppers questioned said milk was too expensive.
Daniella Vega said it was becoming harder to afford.
"And I’m a mum as well, so I need to consume a lot of milk. I spend about $30 to $50 per week on milk."
Diana Strom said she bought the cheapest milk on offer, the Fonterra-owned Dairy Dale brand.
Others like Holly Mills have made switches between types of milk purely on price.
"Trim is probably the cheapest, I think. I used to buy Calci-trim for more calcium but it’s really expensive. It’s about $5 I think."
Some other shoppers thought the price "is what it is", did not buy milk or preferred plant-milk alternatives.Angela Doran said the issue was not just about milk at all.
"I’ve just been overseas and their milk is much cheaper, as are all of their groceries."
Helen Paddon, however, reminisced about the "good old days".
"I’d like to go back to how it used to be when I was a kid, and they would drink the milk straight out of a cow."
