A dramatic rise in the popularity of farmers markets has left a shortage of producers.
The chairman of Farmers' Markets New Zealand, Chris Fortune, says the number of farmers markets has grown from 21 to 42 in the past three years.
Another six markets are set to open shortly.
Mr Fortune says that has created a problem of too many markets and not enough producers.
He hopes a project to authenticate all 42 of the country's farmers markets over the next 18 months will attract more producers keen to sell in a high-quality market.
