The company had been harvesting beetroot for about six weeks, longer than previous seasons, and would continue until the end of April, Angland said.
The huge extra volume was for the Australian market.
"As it happens, we've had very favourable conditions for this crop in the Bay this year, with occasional rain but no prolonged heavy downpours," he said.
"We have an excellent quality crop, including baby beets and the big retail and food service varieties."
The beetroot line at Hastings had been upgraded at a cost of $5 million to cater for the increased volume.
Wattie's said it had purchased two new beetroot harvesters from Denmark to harvest the larger crop.
