While the suppliers keep secrets, the farmers talk politics.
Farmers deny they are making a lot of money on milk. They point the finger of blame away from the farmgate and towards the shops.
One of the local farmers Carly Gibbs spoke to claims the public should not focus on the price of milk in the shops, but the benefit we get from high overseas milk profits. He admits it's hard for the public to get our heads around.
It certainly is. Parliament's commerce committee inquiry into the price of milk must challenge every stage in the milk chain.
New Zealand consumers have a right to know if this is a fair market or a monopoly which is creaming us.
