Hundreds of kilograms of blueberries stolen from a Hawke's Bay orchard will likely be sold at street markets across the country.

Workers at Bay Blueberries, just south of Hastings, arrived at work last week to find their berry bushes bare and thousands of dollars worth of produce stolen.

Owner Marian Hirst says the thieves would have needed vehicles, equipment, crates and some lights. She says at least a dozen people, from pickers to gate staff, will now not get paid.

Hawke's Bay Grower's Association president Brydon Nesbit says petty theft of fruit around harvesting season happens every year.

"People go in there and take bags of apples, some bags of fruit, maybe sweetcorn which still isn't good - it's stealing from growers. But it's not common to have that amount of produce stolen all at once," he says.

"It seems like a pretty organised outfit who's gone in there. They've got a purpose to steal all that fruit and I imagine they have taken that to market."

He says it's likely the blueberries have been dispersed around the country, mainly in the north.

"These grower markets or street markets where people sell produce. Those kinds of places.

"No one will know. The people selling them won't know, the people buying them won't know that they have been stolen. It's really unfortunate."

Nesbit says the loss of an entire season's produce could put orchards in the region still recovering from Cyclone Gabrielle out of business.

"Many growers have gone through a huge amount of turmoil and have spent a lot of money to get their crops back up and running. Some growers have even pulled out because it's been too much for them.

"For them to work so hard to spend so much money to get a crop and then to have it whipped out beneath them is absolutely devasting. My heart goes out to the company. It's an appalling thing to have happen."

Nesbit says it's not the first time a theft of this magnitude has taken place.

"There's been growers of apples that have had trucks and forklifts come into their blocks at night. Organised groups picked 20 or 30 bins of fruit - containing 2000 to 2500 apples.

"They've picked all that fruit at night, under light, put it on trucks and stolen it. That has happened down here. It's something they contend with all the time."
