Hamilton mother of two Dianne Firth said she wanted to try raw milk and was encouraged when her daughter's eczema cleared after three months.

"It doesn't happen quickly, it is a progressive thing that happens over time," she said. "The only difference was we'd gone off having store-bought milk."

At $5 for two litres or $2.50 for one, the price is not much different to that of silver top milk at $5.70, the closest product to raw milk in the supermarket, Dianne said.
